Do-it-yourself bath roof: single-pitched and gable. We disassemble the bones, how to make a roof for a bath Mounting a roof for a bath with removal

Bath - a complex engineering structure, the construction of which with my own hands feasible, but would require engineering expertise and time. special attention and the roof requires calculation, since the greatest heat loss occurs through the coating - from 30 to 45%. The construction of a roof requires a balanced approach and an accurate idea of ​​the type, construction of the roof and the material of its coating even before construction begins.

Stages of building a roof over a bath

Work on the installation of the roof on the bath, taking into account all the standards and rules, is carried out in several stages:

  1. The choice of roofing option, coating material and load-bearing structure.
  2. Collection of loads, execution of drawings and calculations of the supporting structure, preparation of estimates and a list of necessary materials.
  3. Purchase of material, preparation of the construction site and necessary tools.
  4. Construction.

Choosing a roof option

The choice of roof structure is influenced by the coating material, the purpose of the attic space - whether it will be heated with a residential attic or cold, as well as the level of wind and snow load in the region where the construction is being carried out.

Types of pitched roofs used in individual construction:

  1. Shed. Sloped roofs with a single slope are often used to cover small structures such as bathhouses when needed to be built quickly and inexpensively.

    Shed roof has the most simple design and build very fast.

  2. Gable. If you need a larger roof slope and want to have a full-fledged attic, they construct a more complex gable roof.

    The gable roof is more difficult to install, but it allows you to get a full-fledged attic for storing bath accessories

  3. Hip and semi-hip. Such roofs have 4 slopes - instead of gables on the ends of the house, they also cover with a slope. Roofs of this type are built in climatic regions with a large wind load. The roof, in which the end slopes - hips - descend half the length of the main roofing, are called semi-hip.

    The hip roof resists strong winds well due to the installation of additional slopes instead of end gables

  4. Tent. This is a special case hip roof, which is built over houses that are square in plan, as well as over bases that fit into a circle.

    The hipped roof is arranged in the same way as the hip roof, but does not have a ridge, since all the hips converge at one point

  5. Multipliers and combined. Multi-gable roofs are used to shelter L-shaped or U-shaped buildings that are complex in terms of structures, and at the same time they can be used in coatings different types roof shapes.

    Multi-gable roofs consist of several roof structures combined into one

  6. Attic. This is a very popular type of roof for residential buildings. They are the most different shapes, but they are united by the presence of a warm living space in the attic space. There are such roofs in the baths.

    Device mansard roof allows you to get a full-fledged living space on the second floor

The easiest option for construction is a pitched roof. It is often used when the bathhouse is attached to the main house, and with small coating slopes. When building separately standing bath the most popular gable roof shape.

Roof design

Factors affecting the design of the roof:

  • snow load on the roof, which is determined based on the geographical location of the construction area;
  • normalized resistance to heat transfer, also depending on the climatic region. This parameter affects the choice of insulation thickness;
  • structure weight. It depends on the material of the roof;
  • choice between attic and attic. Insulation of the roof above the attic affects its design and gives an additional load on the rafters;
  • type of bath - an attached room or a separate building: the extension can be covered with a shed structure, while it is more economical to complete a separate building with a gable roof;
  • roof slope. His choice is influenced by the material of the roof, as well as the intended purpose of the under-roof space and the personal preferences of the owners.

Collection of loads on load-bearing elements of the roof

Snow and climatic regions are determined individually according to the maps attached to SP 50.13330.2010 "Thermal protection of buildings" SNiP 23-02-2003, updated edition. These maps are used to determine the specific snow load on the roof in winter period. The load from the weight of the coating varies from 6 kg / m 2 (Ondulin) to 55 kg / m 2 (ceramic and cement-sand tiles).

Having planned over the bath warm attic, to the weight of the roof, add the weight from the insulation, the vapor barrier layer and the interior cladding of the room - from 30 to 55 kg / m 2, depending on the type of insulation and facing material. If the attic above the bath is not heated, then only the weight of the roofing membrane is added, which can be neglected.

The weight of coniferous wood (pine, spruce, larch), from which roof structures are most often made, is determined as the product of density and volume. The density of wood is 600 kg/m 3 .

Table: specific snow load depending on the region

region number1 2 3 4 5 6 7 8
80 120 180 230 320 400 480 560

The region number is determined by the snow load distribution map issued by Roshydromet.

Each region of our country is assigned a number depending on the average snow load intensity.

The height of the passage under the roof slope is normalized and should be at least 1.6 m in order to be able to perform periodic inspection of the technical condition of the structures.

When choosing a roof slope of up to 20 o, the coating can be made of metal profiled sheets, including metal tiles, with a slope of 20 to 40 o, any roofing material can be used, except for rolled roofing bitumen-polymer materials.

Table: roof slope depending on the coating material

Structural calculation of rafters

The calculation of roof structures is carried out in accordance with SP 64.13330.2011 "Wooden structures", but tables with averaged data can be used. This method is much simpler, although the result will be slightly higher than the design minimum, since the tables are designed taking into account the maximum loads from snow and the weight of the roof. To determine the section of the rafter, it is enough to know the span of the building and set the distance between the rafters.

Table: the length and size of the section of the rafters, depending on the distance between them

Rafter length, mDistance between rafters, cmRafter section size, cm
until 3120 8 x 10
until 3180 9 x 10
up to 4100 8 x 16
up to 4140 8 x 18
up to 4180 9 x 18
until 6100 8 x 20
until 6140 10 x 20

When purchasing material, remember that the length of the rafters in this case is the size from support to support, that is, in fact, the rafters will be longer for the overhang of the roof eaves and trimming in the tong.

Lathing design

The design of the crate depends on the coating material:

  • covering of metal tiles on the eaves and ridge of the roof requires a continuous flooring to a width of 450 mm, the step of the intermediate lathing corresponds to the transverse profile of the corrugations and is assigned by the manufacturer of the material;
  • Roofing from bituminous tiles (for example, "Shingles"), tiles, small slopes of roofing from corrugated sheets (Euroslate Ondulin) require continuous flooring from boards or moisture-resistant board materials (OSB, DSP).

The Roof Rules (SNiP II-26-76) standardizes the minimum size of the lathing elements at 30x50 mm.

Execution of a set of drawings

Roof drawing set includes:

  • roofing design;
  • wiring diagrams of load-bearing elements;
  • detailed drawings of each structural element;
  • attachment points;
  • roof section with a flag, which displays the layered composition of the roof;
  • material requirements list;
  • general data on drawings with instructions for installation and requirements for materials.

The most commonly used sections of the timber truss system

When calculating the distance between the rafters, it is necessary to take into account the presence of vertical structures, for example, a chimney.

It is impossible to complete drawings without an engineering education, so individual builders draw elements by hand or print out detailing of nodes from technical literature and specialized Internet sites. However The best decision- ordering a roofing project in companies specializing in this type of work. In this way, all the requirements of current regulations will be met, which guarantees the durability of the roof structure.

On the wiring diagram of the rafters indicate all dimensions in horizontal projection The sections show the required dimensions, elevations, marked elements of the system and nodes On the drawings of the nodes, the designs for connecting elements are worked out The required dimensions, the layered composition of the roof are given on the node, individual elements are marked According to the drawings, element-by-element statements are made indicating the quantity / volume / weight

Installation of a roofing system for a bath

We will analyze the sequence of the roof device for the bath using the example of a gable roof structure.

Required Tools

To build a roof, you will need a set of measuring, cutting and carpentry tools:

  • roulettes of different lengths from 5 to 20 meters;
  • marker, pencil;
  • cord along the length of the skate;
  • hammer nail puller;
  • metal scissors;
  • roofing knife;
  • putty knife;
  • scotch;
  • a hacksaw, an electric saw, an electric drill and a screwdriver, various drills and nozzles for them;
  • horizontal and vertical level;
  • rail, ruler;
  • mounting foam and silicone sealant.

Tools must be kept in the tool bag while working on the roof.

For the safety of work, it is necessary:

  • safety belt, rope;
  • protective glasses;
  • mittens;
  • overalls set.

Step-by-step instructions for installing a gable roof

Roofing begins when the beams are mounted attic floor. Before starting work on the beams, running decks are made of boards or chipboard, DSP, OSB boards that can withstand the load from a person and the structure being mounted. All wooden roof structures are impregnated with a flame retardant, antiseptic and fungicide or a complex protection against fire, decay and fungus.

All elements of the coating are prepared for installation on the ground according to the template. Finished roof trusses are lifted to the installation site and temporarily fixed with boards.

Assembly work is carried out in the following sequence:

  1. Installation of the support beam - Mauerlat. Mauerlat, which ensures the stability of the roof and transfers the load from the roof to the walls of the house, is preferably made of dense hardwood that is resistant to decay (oak, maple, larch). The minimum size of a beam is 100x100 mm, most often a beam of 100x150 mm is used, placing it at least 5 cm from the outer edge of the wall. The beam is fixed to the wall through a gasket made of waterproofing material on the studs laid during the construction of the wall. The holes for the studs are evenly spaced along the length of the beam, not combining with the attachment points of the rafters. The holes for the studs are marked and drilled before the beam is raised to the design position.

    Mauerlat is attached to the wall with evenly spaced studs, previously embedded in the frame

  2. Assembly truss system. The assembly of a structure consisting of a pair of rafter legs and a puff is easier to perform on the ground according to a template. In this case, all roof trusses will have identical dimensions. True, the weight of the structure can be significant, and a crane is required to lift it.

    Rafter trusses are easier to assemble on the ground and then lift to the roof

  3. Installation of roof trusses. First, structures are installed at the ends of the house, temporarily fixing them with mounting boards, racks and struts. For ease of installation of subsequent elements in the ridge, a cord can be pulled between the installed trusses. Then intermediate trusses are mounted. After all the elements of the truss system are installed, they are finally fixed at all points and temporary supports are removed.

    To simplify the installation of intermediate trusses between the extreme rafters, you can pull the cord

  4. Installation of a superdiffusion membrane using a counter-lattice, installation of the main batten. With the help of a counter-lattice, we attach a superdiffusion membrane to the rafters. Depending on the selected coating material, we mount the crate - sparse or slab flooring.

    During installation roofing cake it is imperative to maintain a ventilated gap between the membrane and the roofing

  5. Cover installation. The laying of the coating material is carried out from the bottom up from the left corner. The work is carried out according to the manufacturer's instructions. Perform all necessary connections to vertical structures (for example, a chimney), The roof ridge is closed with a special ridge element.

    Sheets of metal tiles are attached to the crate with self-tapping screws with a neoprene gasket

  6. Mounting drainage system(if provided by the project). The drainage system protects the walls from excessive moisture. With a cornice height of up to 4 meters, its device is optional, but the presence gutter and pipes will increase the life of the building, and the costs will pay off handsomely. It is better to purchase a set of gutter systems at the same time as buying a roofing material, matching the color of the roof or a contrasting color, depending on the taste of the owner. The drainage system includes:
  7. Installation of building gables, filing of cornices. In buildings made of masonry material, gables are usually made of wall material. In houses made of timber or logs, the pediments are sewn up after the installation of the rafters, fixing racks and girders on the end pairs of trusses, along which they are sewn with boards or metal profiles.

    The gables of the baths are usually sewn up with siding or wooden clapboard along the crate fixed on the end truss truss

Lastly, the cornices are hemmed and spotlights are mounted in the cornice overhang.

If you do not feel able to correctly calculate the truss system, complete the drawings and build the roof - entrust this part of the work to professionals. If you decide to overcome difficulties on your own, remember that the construction of the roof will take more than one week, because all work requires accuracy and consistency.

Do-it-yourself bath roof - construction instructions

Types of roofing for a bath

In most cases, there is a gable or single-pitched roof for a bath. More complex designs are not justified due to the small area of ​​​​the bath house and the high complexity of their implementation.

The easiest option is a bath with a shed roof. It is justified if the bath is adjacent to the wall of a house or a higher building. Based on the low cost and ease of installation, most often such a roof is found on small household plots. garden plots.

Despite its relative complexity in construction, a do-it-yourself gable roof for a bath is much more popular. Under such a roof it is possible to equip cold attic for storing bath brooms and other accessories, or to equip an insulated attic where you can equip a creative workshop or summer living room.

So that the insulated attic is not damp, it must be mounted on the ceiling good waterproofing. As a heater, they use: mineral building wool, polystyrene foam, penoizol and other suitable heat insulators. It is necessary to insulate both the under-roofing plane and the attic floor.

The design of the roof of the bath and the features of its assembly

power frame all roof structure serves as a truss system. Unlike a residential building, the bath truss system is carried out according to simplified schemes. If the size of the bath building is small, then the roof trusses can be assembled directly on the ground and fed up on ropes. This method is distinguished by convenience, speed of construction and dimensional accuracy of each farm.

The second option is to assemble the "skeleton" of the roof right at the top. Upper assembly requires good experience, care and precision in work.

Attic floor installation

Given the lightweight design of the bath structure, not concrete beams, but a wooden beam, are taken to equip the attic floor. With brick, rather than wooden walls, metal channels or load-bearing profiles can be used instead of timber. The support of the ceiling and at the same time the basis of the roof is the Mauerlat or the upper beam of solid wood walls.

A well-dried timber 100x80 or 100x100 is taken for the overlap. The bearing elements of the floor are installed flush into the grooves selected for them in the body of the Mauerlat. Depth of notches not less than 70 mm. This method is called blind cutting.

Alternatively, floor beams can be laid on top of the mauerlat and serve as a support for the truss system. Thanks to this solution, it is possible to significantly increase the protrusion of the edge of the roof beyond the walls of the building.

The optimal beam span is up to 4 meters. Maximum - 6 meters. With a greater distance between the walls of the bath, you will have to use special profiled composite lumber or metal trusses.

A draft floor is stuffed over the beams. From below, a waterproofing membrane is hemmed to the beams, and a lining or other ceiling material is attached to it.

When laying the wiring in the bath, do not forget about safety

If wiring is laid in the ceiling, it must always be laid in a polymer sleeve. Connections in the floors of wooden structures are not allowed!

Do-it-yourself bath roof: construction instructions

Let's consider the simplest option, how to make a roof in a bathhouse with your own hands - when the roof trusses are assembled on the ground and fed up for installation.

The farm itself consists of the following parts:

  • two rafter legs;
  • crossbar;
  • base.

A 40x100 or 50x100 edged board is suitable for rafter legs and a crossbar. The base is used as an auxiliary element and serves for rigidity during lifting up and mounting the truss. Subsequently, the base is removed.

truss system

How to make a bath roof with your own hands and save on material? Use the option in which the truss base boards are at the same time the load-bearing beams of the attic floor. In this case, the roof trusses will have to be installed in increments, according to the design requirements for the load strength of the floor beams.

Rafter legs are attached to each other end-to-end or overlap. The crossbar is also better to overlap. Since fastening with nails loses strength over time, we recommend using threaded studs or bolts. A good option is to fasten the elements with metal plates on long screws. If the screws are very thick, we recommend drilling relief holes for them, slightly smaller than the diameter of the screw. Otherwise, thick screws can cause cracking, and the board will lose its strength. The installation height of the crossbar is chosen so that the height of the ceiling of the under-roofing room is comfortable enough.

First, extreme trusses are installed and fixed with temporary supports. Then two boards of the crate are stuffed on top, forming a ridge. The rest of the farms are brought from below these boards and are also attached to them. To control the verticality of the installation, it is most convenient to use a plumb line.

crate

In our case, the lathing serves not only as a basis for roofing, but is also part of the "skeleton" of the roof, since it acts as a truss truss structure. Therefore, for the crate, it is better to take not slats, but wide boards. The step of stuffing the crate depends on the type roofing material. The crate should protrude beyond the extreme rafters by 25-35 cm.

Under a hard sheet roof such as slate or metal tiles, boards can be stuffed with gaps of 20-30 cm. A soft roof for a bath requires a continuous crate. It is even better to use not boards for this, but waterproof plywood or similar durable sheet material. In any case, at the ends of the boards (and preferably in other places of attachment to the rafters) there should be two attachment points. The crate can be stuffed with nails, but it is better to use special notched nails for this. As practice shows, they loosen less and hold securely in wooden structures, even after many years of operation.

How to make the roof on the bath strong and durable

The higher the roof, the stronger the wind presses on it. If the rafter structure should still be further strengthened with internal jibs. They will increase the rigidity "for folding", and will protect the roof from the strongest winds.

We equip a doorway and a viewing window on the extreme roof truss

For an opening from suitable bars we knock together door frame ready door leaf. We attach the box to a crossbar or a transverse beam thrown between the rafters. The lower part of the box is attached to the puff, which for this purpose is mounted in the extreme truss truss.

At the opposite end we equip the viewing window. After that, we sheathe the gables with boards and, if desired, ennoble them with siding. To avoid the gradual distortion of the box due to the weight of the door, we reinforce the upper places with jibs.

Waterproofing is laid on top of the crate. To do this, use special vapor barrier membranes, sheet roofing material or glassine. For a hard roof, roofing material or other viscous bituminous insulation is preferable. It more reliably seals the passage of roofing screws. Under a soft coating for the roof, you can use any waterproofing material.

We lay the roof

The material depends on the desire and ability of the owner. To make the roof in the bath look beautiful - choose modern roofing materials. Installation of the selected roofing material is done according to the manufacturer's instructions. Compliance with his recommendations is the best guarantee of the durability of your roof.

Waterproofing can be laid both along and across the slopes. In practice, transverse laying protects against moisture more reliably. To do this, the first layer spreads along the lower edge of the roof slope, each next one overlaps by 15-20 cm on top of it. An effect similar to fish scales is obtained: water easily rolls down the slope and does not linger anywhere. If the waterproofing is rolled from top to bottom, then it is advisable to glue the seams with adhesive tape (for membranes) or fill it with liquid bituminous mastic (for roofing felts or roofing material).

From below, between the rafters we fix mineral wool. It is needed not only for thermal insulation, but also to reduce noise from rain and hail. Then we hem the insulation with a vapor-permeable membrane and close it with decorative trim.

Outcome

As you can see, there is nothing particularly complicated in the construction of a roof for a bath. To do this work is within the power of an ordinary summer resident. You will need the help of another person, but you can do without the expensive work of specialists. The construction instructions will tell you the sequence of work, and the skills will appear in the process of work. The experience gained during DIY construction will help you quickly fix problems associated with roof repairs many years later.

A gable roof with an attic is the best solution for creating robust design in the bath that meets all standards. It is functional and with the right approach can be a good decoration. But in order for the gable structure to meet all the tasks set, it is necessary to design it correctly.

Advantages of a roof with two slopes

In some cases, you can get away with installing a simpler roof with one slope. But if you think about it, the financial expenses do not differ so much. Moreover, in terms of functionality, a gable roof has a number of advantages:

  • the possibility of arranging a residential attic space or adapting it for bath accessories;
  • high degree of thermal insulation of the bath ceiling;
  • with the correct organization of the ramp, the structure will last as long as possible without repair and additional care;
  • decent appearance.

A simple example of a gable roof: 1 - rafters; 2 - transverse fastening; 3 - Mauerlat; 4 - ridge beam.

What will be needed at work?

You can design a gable roof on a small bath yourself, but first you need to decide on the materials. This is not only the wood used to assemble the frame, but also the coating responsible for the angle of inclination. For each type of material, its own indicators are recommended:

  • ondulin - 3-15 degrees;
  • metal tile - 27 degrees;
  • euroslate - 27 degrees;
  • seam roof - 18 degrees;
  • roofing material - 5 degrees;
  • corrugated board - 8 degrees.

The indicators are dictated not by the decorative finish, but by the weight load on the roof frame. The heavier the material, the more you need to make the angle of inclination. Gentle slopes, under the influence of precipitation (snow) and the load exerted by the coating, can break through. In addition, heavy construction will create an additional load on the foundation of the bath. This also needs to be taken into account.

When choosing a material and determining the angle of inclination, it is recommended to take into account the climatic features in the region. If the precipitation is not intensive, then the given indicators for each material can be changed.

In addition to the coating in the construction of a gable roof on a bathhouse and other structures, lumber is required:

  • mortgage beam (Mauerlat) it is made of a material with a cross section of at least 150x150 mm;
  • roof trusses are wooden beams 50x100 mm;
  • an unedged board is used as a crate.

In addition, you will need a film to isolate the steam passing from the steam room and washing department and a heater.

Stages of assembling a gable roof and truss system

The roof in any constructive plan is a frame sheathed with roofing. All work is carried out in strict sequence.

Mauerlat is installed first. To do this, a beam of 150x150 mm is laid along the upper part of the walls and fastened to the studs. They are immured in advance at the stage of laying the walls of the bath from brick or other material. There is also a wire fixing option. For this, segments of the required length are laid between the penultimate and last crown of logs, if the bath is built of wood, or in brickwork. Mauerlat must be laid evenly, both horizontally, and check the diagonal of the structure.

In the Mauerlat, grooves are cut for laying the rafter legs, at a certain distance. If a Wall panel thicker than the base of the roof, it is additionally wrapped with roofing material in several layers and laid with bricks on the outside to increase strength.

Next, you need to assemble the truss structure. This is a rigid triangular bundle of timber. To further strengthen them, a spacer is mounted across each. A crossbar is installed at the top of the corner. It is mounted after the installation of the rafters, and it is better to assemble them on the ground, having previously “removed” the dimensions.

When the required number of rafters has been collected, they must be installed on the Mauerlat. The ridge corners are mounted first. Trim and attach to the Mauerlat. Everything is ready. Of all the types of bath roofs with two slopes, the process of installing the main rafters in this system is the simplest. At the end of the work, the evenness of both structures is checked. Next, the rope is pulled along the top of the corners and the rest of the trusses are mounted relative to this landmark.

After installing all the rafters, we check the evenness of the installation and carry out a control fixation to the Mauerlat and the ridge bar. If the roof slope is more than 4.5 meters, then you need to additionally install props, so that on one side they hold rafter leg, and the other rested against the floor beam.

Finishing work according to plan

The skeleton of the roof is assembled, it remains to carry out the final work. First of all, we determine the place where the chimney exits, if it is not laid through the wall. We mount a metal adapter and isolate it with a heater.

Next, we fasten the vapor barrier layer to the rafters with staples of the stapler. On top of it we stuff a crate from an unedged board. The step is selected according to the type of roofing material. Under roll coatings, continuous sewing; for sheet materials, boards can be fixed at a distance of 15–20 cm from each other. The crate is stuffed throughout the entire truss system, with a protrusion beyond the lower edge by about 20 cm. You don’t need to do more, and if the trusses are longer, then they are sawn off at the same distance.

No need to rush to lay the cover. First, you need to give it additional strength by sewing up the end parts. For this you need a board. AT brick baths, the stone is laid out, with the sewing of the gables. If you plan to use the attic space, leave space for the installation of a window frame.

When the structure is sewn from the gables, it will be much stronger. Now you can proceed to the next step. Waterproofing is laid over the crate. In some cases, the membrane used for this purpose is laid between the rafters, under the counter-batten. This allows you to create an additional air layer for quick drying of the roof structure and additional ventilation of the bath ceiling from the attic space.

Laying roofing material

Most final stage assembly gable roof. The laying principle is the same for all types of coatings. It is necessary to start from the bottom of the cornice and gradually rise, overlapping the lower rows with the next layers. Make sure that the laying is even so that the appearance is not spoiled by curved lines. Having closed both slopes, we install the ridge bar, fixing it with self-tapping screws.

The process of assembling a gable roof is over. This is the easiest option for designing a truss system. Taking into account the advice, you can independently design a reliable roof on the bath that meets all technological requirements.

The final process in the construction of the bath box is the overlapping of the roof. After that, you can already begin to finish the bath from the outside and from the inside, as well as purchase various equipment and accessories for relaxing in the bath. In order for the bath to serve for a long time, and its ceiling does not leak during rain, it is necessary to properly mount the roof, as well as provide it with good heat, steam and waterproofing. Next, we will consider in detail the process of building a bath roof with our own hands.

Before we move on to do-it-yourself roof construction technology, you need to understand the elements of the roof frame, as well as the basic terms that roofers use.

The main purpose of the frame is to support its own weight, the weight of the roofing material, as well as the weight of snow, rain and auxiliary equipment (for example, a module or a satellite dish). That is why the strength and stability of the frame are important indicators.

The roof frame of any building consists of a mauerlat, truss truss, battens and roofing material.

It is called a wooden beam, designed to connect the base of the building box (body) with the roof frame. It is with the creation of the Mauerlat that the installation of the bath roof frame begins. If the bath is made from a log house, the uppermost crown can serve as a Mauerlat, but if the bath is made of foam block or brick, the Mauerlat is laid on the material to be welded. The Mauerlat is fastened to the walls using long anchors. Before installing the Mauerlat on the walls of the building, it is necessary to cut special holes in it for attaching the rafter structure. The main requirement for installing a Mauerlat is its ideal horizontal position, because. the quality of fastening the roof frame to the body of the building will depend on this.

The next structural element of the roof frame - roof truss. The purpose of the truss truss is to evenly distribute loads over the entire roof. There are several forms of truss truss, we will talk about them a little later. The truss truss consists of wooden beams connected to each other. The main element of the truss truss is the rafters, to which the auxiliary elements are attached. As for the latter, they include crossbars, ties, spacers and lintels, the purpose of which is to strengthen the structure of the truss truss.

Frame crate the roof of the bath is designed so that it would be possible to carry out high-quality fastening of the roofing material to the rafters. The crate is presented in the form of wooden bars and boards fastened into a grid. The number and size of the cells of this grid is calculated based on what material the roof will be covered with. For example, to cover the roof with roofing felt, there should be no empty space at all (maximum 1 centimeter slots), and in order to cover the roof of the bath with corrugated board, you can create a crate with cells 0.5 meters wide.

roofing material the roof of the bath is chosen according to the taste of the owner of the building. The most popular materials for the roof of the bath roof are corrugated board, metal tiles, slate and roofing material. Each of the listed materials has its own installation features and requirements for the angle of the roof. For example, a roof with an angle of 5 degrees is covered with roofing material, 8 with corrugated board, about 30 with metal tiles, and 20 with slate.


Most often installation gable roof for a bath is carried out if the owner is going to make an attic space in the bath.

There are two ways to install rafters when creating a gable roof:

The design of a gable roof is more popular than a single-pitched roof, because. in this case, the angle of inclination of the roof will be sharper, which will prevent the formation of snow marks on the roofing material. A gable roof is a series of isosceles triangles, identical in size and shape, installed in the same place along the entire roof. The top of the wooden triangle of their rafters is usually called the ridge, and the transverse wooden beam under the top of the triangle is called the crossbar. The crossbar is designed to strengthen the structure of a gable roof. The smaller the installation step of the truss trusses, the more stable the construction of the bath roof will be. We draw your attention to the fact that roof trusses are assembled on the earth's surface, after which they are fed to the roof. The roof trusses are fastened to the body of the bath after they are installed. ceiling beams(can be done later). To make it easier to create identical wooden triangles, master roofers use special blanks.

Installation of a gable roof is carried out as follows:

  1. Mauerlat is attached to the wall of the bath
  2. A truss truss is being created
  3. Two roof trusses are installed at opposite ends of the roof. To fasten the rafters to the Mauerlat, wood grouse screws are used.
  4. To ensure the stability of the fixed roof trusses, the structures are additionally reinforced with special struts.
  5. A rope is pulled between the extreme rafters at the level of the ridge, which will show the exact installation location of the remaining truss trusses (so that the row runs smoothly, in one line)
  6. The rest of the roof trusses are installed along the rope in the same way.

Installation of a shed roof for a bath is a less popular event, because. in this case, the angle of inclination of the roof will be more gentle, which entails the formation of snow marks on the roof of the bath. Very often, under the weight of snow, roofs begin to deform and collapse.

You can see the design of a pitched roof on this project:


As you can see, the rafter supports of different heights rest on the walls of the bath and hold the entire roof frame. The greater the difference in height between the supports, the steeper will be the angle of incidence of a shed roof for a bath. We draw your attention to the fact that the installation of a sloping roof will cost an order of magnitude cheaper than the installation of a steeply dipping one.

As in the case of a gable roof, the frame of a shed roof for a bath is mounted on a Mauerlat. Fastening must be done with metal corners as well as copper wire. The installation step of the truss trusses should be about 0.6 meters. In order to protect the outer walls of the bath from rain, it is recommended to take out the rafters outside the bath box at a distance of 0.3 to 0.5 meters.

You can see more details on the construction technology of a single-pitched and double-pitched bath roof with your own hands in the detailed video tutorials:

Construction of a gable roof bath

Do-it-yourself installation of the truss system of the bath

After the bath roof frame is mounted, it is necessary to carry out hydro, steam and thermal insulation of the roof.

Measures for waterproofing, vapor barrier and insulation of the roof of the bath

Roof steam and waterproofing


Initially, you should pay your attention to the fact that the roof frame must be made of well-dried lumber. Besides wooden bars and the boards must be manually opened, which will prevent the wood from rotting and increase its service life.

For steam and waterproofing of the roof of the bath, it is recommended to use roofing material (for waterproofing), as well as a membrane film. The roofing felt is attached to the rafters in 2 layers, this will provide a sufficiently high protection of the roof frame from atmospheric precipitation.

As for the membrane film, it is a good heat-insulating and waterproofing material. In order for the film to function properly, it must be laid on the rafters and fixed with construction tape. Strips of membrane film must not be wider than 15 cm. Each new strip must overlap the previous one. We draw your attention to the fact that it is forbidden to stretch the film on the rafters, this can lead to damage as a result of lumber deformation (expansion, narrowing) during heating and cooling (hot summer).

Bath roof insulation


Speaking about the insulation of the roof of the bath, you need to pay attention to a few important nuances this event:

  • It is recommended to insulate the bath roof with mineral wool. It does not burn, is durable and holds heat well.
  • It is not recommended to use polystyrene foam to insulate the roof of the bath with your own hands, because. this material emits harmful substances when heated.

The construction of the bath is completed with fastening roof structure, single-pitched and double-pitched roofs are possible here. The second option is the most popular. This type of roof is quite capable of building on one's own subject to accurate calculations of the angle of inclination of the slopes and the power of the truss system.

Also consider using roof space- whether an attic or an attic will be equipped. If you want to build a bath with a veranda under common roof, this also needs to be calculated in advance.

All these details affect ridge height, type of thermal and waterproofing, selection of necessary materials and the complexity of installation work. Of great importance is price structural elements and roofing material.

Benefits of a gable roof

Why when building a roof for a bath choose more often duplex building? It is related to the complex benefits:

  • thanks to the pitched structure, it is provided natural outlet snow and rainwater, so the roof does not require significant maintenance efforts in the autumn-winter season;
  • the practicality of the design allows you to equip under the roof attic, adapted for storing various equipment and drying bath brooms, or a full-fledged living quarters where guests can be accommodated;
  • with a small area, baths in the attic can be equipped technical area with the removal of heating and air conditioning systems upstairs;
  • gable roof installation not too complicated and is accessible to the non-specialist subject to careful preparation and security and during work at height;
  • ridge roof buildings very attractive, have a finished look and allow you to add variety due to the individual decor of the gables and the use of various roofing materials;
  • roof with two slopes lasts a long time and does not require expensive complex repairs;
  • gable roof construction is sufficient economical option m in comparison with the construction of more complex and large-scale roofing systems.

Gable roof device

Before purchasing materials and proceeding with installation, you must familiarize yourself with features gable roof devices. The basis of the design is rafter system, which relies directly on the erected walls if the bath is log-house or from glued beams.

In the case of using other types of wall materials (brick or foam concrete), a support bar(Mauerlat) for attaching the rafter system. Depending on the span between the supporting wall and the ridge part of the rafter, the rafters can be layered or hanging.

As additional roof reinforcements with a span of more than 3 meters install rafter legs (struts) and a rafter headstock to support the ridge run. Install along the entire length of the slope triangular trusses with a certain step.

Rafter with support on Mauerlat it is easier to mount than hanging ones, but it is necessary to take into account the spacer load on the walls and adjust the weight of the truss system. The angle of inclination of the slope is considered optimal 40-50 , therefore, with significant inter-slope spans, the height of the ridge is proportionally increased, which can improve design buildings and become the basis for the arrangement of the attic residential area.

Phased construction technology

The construction of a gable roof bath includes several main stages:

  1. structural calculations and drafting drawing or scheme with sizing;
  2. acquisition and labeling materials, tool preparation;
  3. mounting bearing beams;
  4. installation truss system, including the installation of gables of intermediate trusses;
  5. equipment ventilation pipe outlet from the stove-heater with a refractory casing to prevent the roof from catching fire;
  6. fastening battens;
  7. mounting insulating layers;
  8. flooring roofing materials;
  9. registration ridge part.

The best material for the formation of the truss system is a quality pine timber. Suitable for framing edged board. Roofing material is chosen based on style preferences, budgetary possibilities and the complexity of the flooring.

The most popular roofing material for a bath is considered to be profiled sheet due to the optimal combination of its cost, performance and ease of installation.

For waterproofing it makes sense to purchase membrane materials that are lightweight and at the same time highly effective in protecting the structure and attic space from moisture. Thermal insulation is selected taking into account material weight which is especially important in the construction big bath with several rooms, including a residential attic area.

Gable roof for a bath - construction stages


The construction of the bath is completed with the fastening of the roof structure; a single-pitched and gable roof is possible here. The second option is the most popular. It is quite possible to build this type of roof on your own, subject to accurate calculations of the angle of inclination of the slopes and the power of the truss system. It is also worth considering the use of under-roof space - whether an attic or an attic will be equipped. If you want to build a bathhouse with a veranda under a common roof, this must also be calculated in advance. All these nuances affect the height of the ridge part, the type of thermal and waterproofing, the selection of the necessary materials and the complexity of the installation work. Equally important is the cost of structural elements and roofing material.

Do-it-yourself bath roof: single-pitched and gable

Even at the planning stage of the bath, you need to think about what the roof will be. Its main functions are protective, but do not forget about the aesthetic side. For the simplest structure of the bath, you should not take complex structure roofs. The fewer bends, skates, the more practical system. For a bath, they usually use a gable or single-sided, which can be easily assembled with your own hands. If you do not know how to install a bath roof with your own hands, then this article will become a real helper. We will tell you how to do the work quickly and correctly, introduce you to some of the intricacies and tricks of installation, and help you choose a practical design.

Roof for a timber bath, gable.

Bath roof standard model

There are many roof structures for a bath, but they always take the standard of 2 elements as a basis: a truss bearing base and a roof, which is attached to a crate with waterproofing. By functionality, roofs can be divided into: with and without an attic floor. The first option is more difficult to assemble, but the bath will become functional. The presence of an attic floor does not affect the choice in any way: single-slope and gable. Of course, you can find more complex four-slope ones, but these are rarely assembled with their own hands.

Which roof is better single-pitched or double-pitched?

When choosing a roof structure, you need to build on the following factors:

  1. The location of the building on the site. In attached baths, this is, as a rule, a shed system.
  2. material possibilities. Shed is built mainly to save money.
  3. Features of the layout of the bath. For a building with an attic, it is better to choose a gable.

Scheme of a shed roof for a bath

A shed design is chosen mainly for a bath at a summer residence, when quick assembly is needed at minimal cost. Basically, pitched roofs are low, at a slight angle.

The scheme of the gable roof under the bath.

More often you can find gable structures with a high ridge. If you equip and insulate the roof, you can get additional space. It is convenient to place in such a rest room or a billiard room. Not insulated is used as an attic for storing brooms and dry herbs for a steam room.

What to consider when choosing the height of the ridge or the steepness of the slope

When choosing the height of the skate, you need to consider:

  1. Features of the climatic conditions of the region (windiness, rainfall).
  2. aesthetic aspects.
  3. Features of the construction of the bath.

The roof is gable on a bath from a bar with a slope of 45 degrees.

The angle of inclination of the roof can be from 2.5 to 60 °. A flat roof can be used in a region where the average annual rainfall is low. A steep one is made when an attic or attic room is provided in the design. But in regions with strong winds, too high a skate should not be used. For example, in the steppe regions, where the amount of precipitation is minimal in winter, a sloping roof with a maximum angle of 10 ° is used, in the northern regions large quantity snow - from 45–60 °.

The lower the roof, the less material and physical resources are spent on its installation.

Bath roof support system

The gable roof has a base of slopes that rest on floor beams or are connected to the Mauerlat strapping from above. Mauerlat is a beam that is mounted on two walls of the bath. The floor beams of the gable roof on wooden baths are fixed with the help of special sockets, which are made in the upper crown. Nests must have a strict horizontal, where the support elements are laid.

Floor beams can protrude beyond the walls of the bath. If the support beam protrudes beyond the walls by more than 1 m, then an additional support in the form of a column is installed for it.

For a bath with a shed roof, the beam system is made so that the emphasis on both sides has a different height. Rafter trusses are fixed with girders and rafter bars.

Rafter leg system

The truss truss consists of rafter legs that rest on the upper link of the wall or mauerlat. Two forces act on the rafter legs in the structure at once: compression and bending. Therefore, they need to be made from wood with a diameter of at least 120 mm or timber 60x60 mm. You can make the legs of the truss system from boards 40x150 mm or more.

With your own hands, it is easier to assemble trusses from glued or edged timber. If there are no such materials at hand, you can take boards and splice them with nails or self-tapping screws. You can mount cuts in such legs only at fulcrum.

According to the method of fastening, the rafter legs can be layered or hanging.

hanging rafters

This system consists of rafter legs that rest on top of each other. A skate is mounted at this junction. The anchor points of the hanging hasti are the outline of the roof. Hanging systems are subject to horizontal pressure, which is resisted by a special tightening. The nodal connections of the hanging rafters can be strengthened with rails, but in a lightweight design they can be omitted.

For the construction of a lightweight system from a bar of a small section, it is necessary to perform additional runs. They will strengthen the structure.

The rafter system of a hanging structure should be as rigid as possible, since heavy loads are placed on it during operation. The slope planes are connected with additional diagonal beams, this is especially true in the windy regions of the country.

Rafters

Pitched roof structures are more often used in lean-to types. The system does not use additional puffs, it is as simple as possible. The rafters rest on a power plate, which is mounted on one of the load-bearing walls. They can be fastened with knitting wire or through the Mauerlat with screws or metal studs. The step of the rafters of the layered system is calculated depending on the total load of the roof and winter precipitation. In this case, it is necessary to take into account the selected angle of the slope of the roof of the bath.

Features of the installation of a gable roof truss system

The gable roof system of the bath consists of truss trusses, which should be mounted in series. All of them must have the same dimensions and are installed in one step. The rafter system is needed for laying roofing material, hydro and thermal insulation.

The easiest way is to put together a system of trusses on the ground with your own hands, and then raise it with the help of equipment. The shape of the rafters should resemble an isosceles triangle. If the roof is complex, then the structure can be strengthened with additional overlays and screeds. To simplify the work, you can make a farm template, substitute it in the manufacture of each subsequent one.

First, it is worth installing two extreme rafters and connecting them with a regel. Regel is a transverse beam that connects the farms to each other. You can fix the regel with metal screws. To do this, you need to cut it down and drill holes for mounting.

Rafter trusses must be installed strictly vertically. To do this, they are checked with a plumb line. Deficiencies are leveled by squeezing off excess or lining that does not reach under the rafters.

A short video will help you understand the installation in more detail:

Features of the installation of the truss system of a shed roof

If the distance between bearing walls baths less than 4.5 m, then additional support is not necessary. a Mauerlat is laid on one of the walls, in which grooves are cut for the rafters. On the opposite wall, the same ones are cut in the upper link. Their size should correspond to the rafter so that it fits snugly against the cut. Do not use all possible sealing gaskets.

The rafters should be of such length that they extend 30-50 cm beyond the contour of the walls. This will make it possible to mount a cornice that will protect the walls from rain. The rafters are attached to the Mauerlat and the upper beam with iron spiers or screws.

Roof decking

Further, with any design, a crate is made. Its step must be calculated depending on the material with which the structure will be covered. If this soft roof, for example, andulin, then the crate is made of wide boards leaving a gap of 1 cm between them. For hard sheets, for example, slate or corrugated board, the crate is made of bars with a section of 50x50 mm. The fastening step can be from 15-50 m.

Installation of the crate should begin from the ridge down with a screwdriver and self-tapping screws. On the ridge, the installation of the crate begins with two boards, which should be fixed to it. Next, the roof is waterproofed and covered with the selected material. The ridge and cornices are hemmed.

For roofs with an attic, additional insulation must be performed. You can read about how to insulate the roof of the bath in the following article.

If you do not rush and do the work correctly, then the roof of the bath will serve more than one generation of your family. And its appearance and shape will delight for many years.

Do-it-yourself bath roof: installation, photo and video


Do-it-yourself roof for a bath, which roofs are easier to assemble on your own. Description of the design of a single-pitched and gable roof.

How to make the roof of the bath with your own hands

Most owners of private houses build a bathhouse on their site. Laying the foundation and erecting the walls is only part of the job. It is also necessary to properly make the roof with your own hands, since it will depend on how much the building can withstand precipitation. Only a set of correctly performed works can guarantee you a high-quality result and comfortable conditions in the bath. This can be achieved by following step by step instructions for building with your own hands.

Bath roof designs

Before proceeding with the construction of the roof in the bath, you need to choose best option. It should be as simple as possible, but reliable, as it is needed to protect the building from rain and snow.

Most often, baths are:

The design of the roof itself depends on this. It also affects the frequency of the bath. For one that will be used all year round, it is best to choose a gable with an attic, as it is warmer. There you can equip a room for relaxation.

Summer baths are usually built without an attic, but designed to install a tank of water for heating under the sun. Such a roof is easier to build.

According to their shape, roofs can be:

Shed roofs are the simplest. Usually used when attaching a bath to the main house or other building. At the same time, the rafters firmly rest on opposite walls at a certain angle of inclination.

The optimal angle of inclination is 20–30 °, but if the bath is built in areas with high levels of precipitation, then this parameter increases to 45 °.

Gable roofs are arranged on separate structures. They consist of two parts, connected to each other at an angle. For areas where a large amount of snow falls in winter, the connection angle should be quite sharp (from 45 to 80 °) so that precipitation can easily go off and not press on the roof from the outside. And in areas where frequent winds - minimum slope so that in case of strong gusts it does not fly off the bath.

Multi-pitched roofs are usually not built on small baths, as this is not entirely rational and convenient. But if a large bath complex is being built, then it will be appropriate here. It has a beautiful appearance, and allows you to arrange under your arches additional premises(rest rooms, billiard rooms, storage rooms, etc.). The disadvantage of the roof is the complexity of its construction.

That is why masters often choose this option.

How to make a gable roof scheme

The best option for a small bath is a gable roof. It is inclined and hanging. The first option for greater stability is equipped with additional wooden stops. Hanging systems rely only on Mauerlats or ceiling beams. At the top, the rafters are held on crossbars.

Installation preparation: dimensioning, drawings

For convenience, all calculations will be made for a bath with a side of 5 m. It is recommended to build it from sawn timber, and use the top row as a Mauerlat.

Before making rafters, it is necessary to make all the necessary calculations and measurements, as well as determine the angle of the roof and the dimensions of the wooden elements.

Certain loads act on the roof system:

  • the mass of rafters, lathing and the roofing material itself;
  • weight of workers;
  • the probability of natural disasters (they are not taken into account in our country, as they have a low percentage of the probability of their occurrence).

When calculating the thickness and width of the elements of the truss system, take into account the totality of all types of loads.

The lower elements of the rafters are placed on the Mauerlat, and they bear lateral and vertical loads. Horizontal ones are placed on crossbars. The ridge part of the rafters takes over the compression forces in the horizontal direction. Rafter spans are subject to the greatest degree of bending.

When calculating the load, it is necessary to use correction factors that depend on the height of the house.

There are also snow load values ​​​​depending on the climatic zone.

Belonging to a certain climatic zone can be viewed on a special map.

The choice of material for the roof

Wood used for construction roof frame, should have a minimum number of flaws (first of all, this concerns knots and cracks).

Pine or spruce boards are most often chosen for the construction of the bath roof because of the high degree of strength. This wood is easy to work with. Experts recommend using grade I lumber, well treated with antiseptic and antifungal agents. But for a small bath, grade II or III material is suitable.

You can use glued laminated timber with a high degree of strength without signs of deformation. But this material is expensive.

  • 20% (if the ceiling of the bath is completely sewn up with finishing materials from the inside);
  • 23% (if some elements of the roof will be outside, for example, a canopy over a veranda or terrace).

Timber for roofing should be dried naturally (in a dry room at a low temperature) for 2–3 years or in special chambers at the highest possible temperature.

There are a large number of materials for roofing:

most sought after and available materials are metal tiles and corrugated board, which are characterized by low price and long service life.

The corrugated board is made of galvanized steel with a special coating. Its main difference from a metal tile is the thickness of the metal. For example, profiled sheets with a thickness of more than 1 mm are not intended for roofing.

The advantages of this material:

  • high performance;
  • ease of installation (sheets are easy to pick up according to the exact size of the roof slope);
  • light weight;
  • affordable price.

There are also disadvantages, for example, low soundproofing characteristics, less attractive appearance compared to metal tiles, short service life (about 5 years).

  • high degree of resistance to corrosion;
  • excellent sound absorption, which provides multilayer material;
  • long service life (about 50 years);
  • beautiful appearance.

Despite the positive qualities, it is not suitable for the device shed roofs, since its laying is carried out only at an angle of at least 14 °. The corrugated board has no restrictions.

Ruberoid is an inexpensive, but short-lived material. It is easy to install, does not require much labor. For a budget roof covering for a bath, roofing material can be called a completely acceptable option.

Slate is an affordable roofing material that is suitable for a bath. It has a fairly long service life (about 40 years), does not require additional care. Installation of slate sheets is carried out quickly, which is very important in the final stages.

The disadvantage of this material can be called a high degree of water absorption, therefore, after 2-3 years, moss and various harmful lichens may appear on it - painting will help to avoid this. The large fragility of slate is also a significant disadvantage. Therefore, it is better to pre-drill holes into which fasteners will be driven in.

What material and tools are needed

In order to build a gable roof for a 5x5 m bath, you need:

  • boards (pine or spruce) - 50x150 mm (the distance between the rafters is recommended to be 90 cm);
  • unedged board for temporary fixation of rafters;
  • edged board - 20x100 mm (length 3 m);
  • metal corners;
  • metal plates - thickness 2 mm;
  • bars - 50x50 mm;
  • bolts with washers and self-tapping screws;
  • glued plywood, OSB or unedged board for lathing;
  • slats - 20x50 mm;
  • insulation, vapor barrier and waterproofing material;
  • metal tile or corrugated board.
  • Bulgarian;
  • electric jigsaw;
  • stapler;
  • a hammer;
  • tape measure - length not less than 10 m;
  • sharp knife;
  • electric screwdriver;
  • antiseptics and impregnations.

Construction of the roof of the bath: step by step instructions

To install the roof, you need to follow the following plan:

  1. Check the parallel arrangement of the Mauerlat (the degree of run-up is not more than 2–3 cm). Fixation dowels must be laid at the required distances.

Creation of a crate

The crate can be rack or solid.

All work takes place in several steps:

  1. Creating a crate from wooden slats depends on the selected roofing material. For the subsequent fastening of metal tiles or corrugated board, it is necessary to nail the slats to the slings in increments of about 40 cm. It is recommended to make a template to control the distance between the elements of the crate. Near the ridge, the slats must be nailed with a small step. From the side of the two gables, it is necessary to make a straight line with a special chopping rope. Cut off the excess ends of the rails with a saw.

After the installation of the crate, it is necessary to close the end sides of the roof. If you plan to create an attic, then you need to leave room for installing doors and windows.

Warming from the inside

For insulation, you can use mineral wool 10 cm thick. First, a vapor barrier material is laid on the rafter system to protect against moisture from the interior of the bath.

A heater is laid on top of it, and then a waterproofing material that will prevent the penetration of moisture through the small cracks of the roof.

Protective hydro and vapor barrier films are overlapped about 15–20 cm, then glued together with construction tape.

How to properly cover a roof

Laying roofing material is no less important part of the roof structure than its construction. If you properly cover the bath with a metal tile or metal profile, then you can protect all wooden structural elements from precipitation, which will significantly extend their service life.

For laying metal tiles you will need:

  • roulette;
  • electric screwdriver;
  • building cord;
  • special self-tapping screws (4.8x28 mm and 4x20 mm) with gaskets;
  • long rail;
  • scissors for cutting metal profiles;
  • electric jigsaw;
  • hacksaw for metal;
  • special cutting electric scissors.

Stages of installation of roofing material:

  1. The metal tile is lifted onto the roof frame using special belts. The first sheet is laid, carefully aligned along the end part and the cornice. It is fastened with self-tapping screws at the points of junction of the wave to the laths of the crate. They are screwed in a certain order.

Gable roof for a bath: technology and instructions for building your own hands

A gable roof with an attic is the best solution for creating a reliable structure in a bath that meets all standards. It is functional and with the right approach can be a good decoration. But in order for the gable structure to meet all the tasks set, it is necessary to design it correctly.

Advantages of a roof with two slopes

In some cases, you can get away with installing a simpler roof with one slope. But if you think about it, the financial expenses do not differ so much. Moreover, in terms of functionality, a gable roof has a number of advantages:

  • the possibility of arranging a residential attic space or adapting it for bath accessories;
  • high degree of thermal insulation of the bath ceiling;
  • with the correct organization of the ramp, the structure will last as long as possible without repair and additional care;
  • decent appearance.

A simple example of a gable roof: 1 - rafters; 2 - transverse fastening; 3 - Mauerlat; 4 - ridge beam.

What will be needed at work?

You can design a gable roof on a small bath yourself, but first you need to decide on the materials. This is not only the wood used to assemble the frame, but also the coating responsible for the angle of inclination. For each type of material, its own indicators are recommended:

  • ondulin - 3-15 degrees;
  • metal tile - 27 degrees;
  • euroslate - 27 degrees;
  • seam roof - 18 degrees;
  • roofing material - 5 degrees;
  • corrugated board - 8 degrees.

The indicators are dictated not by the decorative finish, but by the weight load on the roof frame. The heavier the material, the more you need to make the angle of inclination. Gentle slopes, under the influence of precipitation (snow) and the load exerted by the coating, can break through. In addition, a heavy structure will create an additional load on the foundation of the bath. This also needs to be taken into account.

When choosing a material and determining the angle of inclination, it is recommended to take into account the climatic features in the region. If the precipitation is not intensive, then the given indicators for each material can be changed.

In addition to the coating in the construction of a gable roof on a bathhouse and other structures, lumber is required:

  • mortgage beam (Mauerlat) it is made of a material with a cross section of at least 150x150 mm;
  • roof trusses are wooden beams 50x100 mm;
  • an unedged board is used as a crate.

In addition, you will need a film to isolate the steam passing from the steam room and washing compartment and a heater.

Stages of assembling a gable roof and truss system

The roof in any constructive plan is a frame sheathed with roofing. All work is carried out in strict sequence.

Mauerlat is installed first. To do this, a beam of 150x150 mm is laid along the upper part of the walls and fastened to the studs. They are immured in advance at the stage of laying the walls of the bath from brick or other material. There is also a wire fixing option. For this, segments of the required length are laid between the penultimate and last crown of logs, if the bath is built of wood, or in brickwork. Mauerlat must be laid evenly, both horizontally, and check the diagonal of the structure.

In the Mauerlat, grooves are cut for laying the rafter legs, at a certain distance. If the wall panel is thicker than the base of the roof, it is additionally wrapped with roofing material in several layers and laid with bricks on the outside to increase strength.

Next, you need to assemble the truss structure. This is a rigid triangular bundle of timber. To further strengthen them, a spacer is mounted across each. A crossbar is installed at the top of the corner. It is mounted after the installation of the rafters, and it is better to assemble them on the ground, having previously “removed” the dimensions.

When the required number of rafters has been collected, they must be installed on the Mauerlat. The ridge corners are mounted first. Trim and attach to the Mauerlat. Everything is ready. Of all the types of bath roofs with two slopes, the process of installing the main rafters in this system is the simplest. At the end of the work, the evenness of both structures is checked. Next, the rope is pulled along the top of the corners and the rest of the trusses are mounted relative to this landmark.

After installing all the rafters, we check the evenness of the installation and carry out a control fixation to the Mauerlat and the ridge bar. If the roof slope is more than 4.5 meters, then you need to additionally install supports, so that they hold the rafter leg on one side and rest against the floor beam on the other.

Finishing work according to plan

The skeleton of the roof is assembled, it remains to carry out the final work. First of all, we determine the place where the chimney exits, if it is not laid through the wall. We mount a metal adapter and isolate it with a heater.

Next, we fasten the vapor barrier layer to the rafters with staples of the stapler. On top of it we stuff a crate from an unedged board. The step is selected according to the type of roofing material. Under roll coatings, continuous sewing; for sheet materials, boards can be fixed at a distance of 15–20 cm from each other. The crate is stuffed throughout the entire truss system, with a protrusion beyond the lower edge by about 20 cm. You don’t need to do more, and if the trusses are longer, then they are sawn off at the same distance.

No need to rush to lay the cover. First, you need to give it additional strength by sewing up the end parts. For this you need a board. In brick baths, stone is laid out, with sewing of gables. If you plan to use the attic space, leave space for the installation of a window frame.

When the structure is sewn from the gables, it will be much stronger. Now you can proceed to the next step. Waterproofing is laid over the crate. In some cases, the membrane used for this purpose is laid between the rafters, under the counter-batten. This allows you to create an additional air layer for quick drying of the roof structure and additional ventilation of the bath ceiling from the attic space.
