L-shaped extension to the house. Roofs of extensions of private houses in the photo

Solving the housing issue with your own private house is much easier than in a city apartment. The best option is to make an extension that can be used for a variety of purposes:

• a full-fledged living quarters - an additional room;
• living quarters with an attic (if the extension is two-story);
• utility room - its own pantry, which can largely replace the cellar;
• a spacious terrace or veranda where you can spend your holidays with the whole family;
• car garage.

The basics of the technology and step-by-step instruction building an extension to wooden house.

Before choosing a specific building material and technology for building an extension, it is important to clearly define the purpose of the room. It may be worthwhile to immediately plan the creation of an extension in which it will be possible to live all year round - in case of an expansion of the family or the arrival of a large number of guests.

Types of extensions

There are several types of extensions to a wooden house. They differ in material, as well as installation features:

1. frame extensions;
2. from a cylindrical bar;
3. from brick;
4. from cinder block.

Before erecting a structure, it is important to take into account all the nuances that may affect the choice of materials and a specific type of extension:

Do right choice a specific extension project means to correctly correlate the purpose of this structure, the features of the house to which it is attached, with the technology and material of manufacture. To do this, it is important to understand how each type of such structures is built.

Do-it-yourself frame extension: step by step instructions and video

The frame extension has several advantages:

• the design is quite simple, and if everything is calculated correctly, it is quite possible to do it yourself;
• it is built much faster than brick, cinder block structures;
• the design is quite light in weight and does not require much effort during operation;
• in terms of thermal insulation, durability and other consumer qualities, the frame extension to the house is not inferior to others types of structures.

NOTE. If you intend to build a two-story extension, you should consider this option - the structure is lightweight and will not create excessive pressure on the ground, so the risks of subsidence are noticeably reduced.

Preparation for construction

At the preparatory stage, it is important to solve the following tasks:

• What will be the frame material? wooden bars or metal profiles.
• What type of extension will be associated with the main building.
• Accurately calculate all dimensions of the structure and develop a detailed drawing.
• collect all necessary materials and tools.

First of all, it is important to decide on what type the structure will be built - as a continuation of the house with an increase in the main roof for the installation of a single roof or as an adjoining building.

It is clear that the second case will be cheaper, easier and faster - the extension will simply adjoin the wall. You can make access from the house directly to it, if you make an appropriate hole and put the door.

The diagram of the adjoining structure to the house is presented below.

Structurally, this solution is a roof placed on supports. The roof is standardly presented from rafters and supporting boards. For a longer service life, it is desirable to insulate it, lay out a layer of waterproofing. The basis, as a rule, is the usual strip foundation.

Pairing with the main part of the house occurs at 2 points:

• wall;
• roof.

The connection in each of them has its own characteristics, which will be described below. Preliminary sketch of the extension, as well as practical advice things to consider before starting work:

At the same time, for the roof of the extension, it is better to choose a material that is elastic enough to make the necessary corrections. You can purchase corrugated board (height within 1 cm) or soft tiles.

In this sense, slate or traditional ceramic tiles, metal tiles will not work.

The frame is made of wood or metal. At the same time, all parts should consist of only one type of material - then the extension is more reliable and lasts longer.

NOTE. Even if the house is in good condition, but old enough, the rate of its drawdown will be several times higher than the drawdown of the extension. Accordingly, it is better not to use a rigid type of abutment of the structure to the main wall. In this case, another type of installation is used - "groove-comb".

As for tools, no special equipment is required: it is important to have a screwdriver, a saw, pliers, a building level and other woodworking tools.

Installation work must be carried out by at least two people - some stages will require joint efforts.

Foundation laying

The first stage of work is laying the foundation. Since in the overwhelming majority of cases, during the construction of a house, the construction of a foundation for an extension is not provided, the foundation must not only be laid correctly, but also securely connected to the main foundation.

NOTE. If you are designing the construction of a newly built house, it is better to take into account the extension right away. It can be made after some time, and laying the foundation along with the foundation of the main building is a technically correct option. In this case, the house and the extension will be a single entity, which will ensure their reliability.

The main requirements for the base of the extension are as follows:

• reliability - stable maintenance of the weight of the structure without subsidence: especially important for extensions made of heavy materials or two-story structures;
• maximum identity with the main foundation in terms of material and depth of laying;
• the most complete adhesion to the main foundation.

Most often, strip foundations are chosen for an extension, since they are quite capable of coping with such loads. At the same time, installation features always depend on the type of soil. It is possible to lay monolithic foundations, made of brick or concrete blocks, fill them with drainage materials.

Schematic diagrams of the bases are shown in the figure.

The technology for building a strip foundation for an extension does not differ from the usual one. In short, a trench is dug, reinforced and poured with concrete.

Connecting the foundation to the main

This is the most critical step. which needs special attention. Two types of connections are traditionally used:

• "tape-tape";
• "slab-slab".

According to the "tape-tape" type, the stages of work will be as follows:

1. From the installation side of the extension, a trench is dug corresponding to the depth of laying the main foundation.
2. Further, a hole half a meter in diameter is drilled at the base of the house - for the corners of the foundation of the extension. For all other parts, the hole corresponds to the diameter of the reinforcement at a depth of 2/3.
3. The reinforcement is driven into the foundation of the house, for this a wood wedge is used.
4. The foundation of the extension is formed along the driven reinforcement.

Installation according to the "plate-plate" scheme is possible in 2 cases:

• the width of the main foundation allows you to carry out the appropriate work (from 450 mm);
• the plate protrudes from the base (minimum 300 mm).

Thanks to the extension, it is often possible to solve another important task - to strengthen the old foundation and thereby support the sagging house. Visual video instructions:

Features of laying the foundation in the case of an old house:

Installation of the floor in the annex

Correctly making the floor in the future room is important from the point of view of 2 factors:

• thermal insulation;
• surface evenness.

It is important to make a quality floor, especially in cases where the extension to the house will be used as an additional room with the possibility of year-round use.

The strip foundation allows you to mount both a concrete floor and make it out of wood. In the case of a columnar base, it is possible to produce only a wooden covering.

Concrete floor

The sequence of technology for laying this floor looks like this:

The concrete surface is quite cold, so this floor needs careful insulation, especially in the northern regions.

Wooden floor

On a columnar or strip foundation, a floor created on the basis of wooden floors. It needs additional processing to avoid rotting, however wood flooring much warmer than concrete.

The sequence of installation of a wooden floor looks like this:

1. If an extension to the house is being built as a capital structure, then preparatory work for laying sand, gravel or expanded clay, as in the case of a concrete floor.
2. A ruberoid substrate is placed on the foundation.
3. Bearing beams are laid on it. If the foundation is columnar, then they are mounted directly on the poles, the length is cut in accordance with the interval. If the foundation is strip, it is important to install intermediate pillars at a certain interval, or use long beams if the extension is small in area.
4. A wooden covering is mounted on the beams.

All wooden parts must be carefully varnished to prevent decay.

A good example of installing a wooden floor in a cinder block extension is shown in the video.

Frame installation

The next stage is connected with the direct erection of the frame structure. To do this, first of all, you need to install a strapping beam. If it is assumed that the wall thickness is 200 mm, then the dimensions of the end bar will be 25-40 mm, as shown in the detailed diagram.

The end result is a structure that looks like this.

Cutting a groove in the base can be done complete and incomplete. Can be articulated without punching using a steel angle.

The lower strapping is performed in several stages:

1. The socket is mounted in a frame.
2. The overlay is nailed into the base.
3. The support stand is attached with a bracket.

The upper trim is formed for reliable installation of floor beams, as shown in the diagram.

NOTE. The interval between vertical supports must be at least 50-60 cm, since in this case it will be easy to lay insulation (mineral wool, foam plastic, ecowool, etc.). In addition, there is no practical need for a more frequent arrangement of racks.

The general design of the frame is shown in the diagram.

The walls are erected according to the following algorithm:

• Mounting on a prefabricated foundation bottom strapping. The binding is screwed with dowels.

Between the strapping and the foundations, a waterproofing layer is necessarily placed - foamed polyethylene, roofing felt or other material.

• Vertical bars are nailed to the wall of the house if the two structures are to be rigidly fastened. If you just need to build a nearby building, then corner posts with temporary fastening are first made.
• Mounted vertical bars. Their height is selected depending on the number of storeys of the structure, as well as on the method of connection with the main roof of the house.
• Next, the top trim is mounted.
• The last stage in the installation is the manufacture of holes for windows and doors.

ADVICE. If it is planned to build a large extension with large quantity bars, it is more convenient to assemble the frame separately by installing all the bars on the lower harness. In this case, there is no need to fasten each element with temporary cuts.

Assembly of the roof and its docking with the main roof

The installation of rafters is carried out in the same way as for a conventional roof, however, the need to connect the roof to the roof of the house gives rise to a number of features of this work.

AT general view The finished structure can be schematically depicted as follows.

After the construction of the frame, the material of the roof of the house from the side of the extension must be dismantled so that the rafters appear. It is to them that the connecting rafters of the extension are mounted. Installation is carried out according to the principle of a rigid triangle, while it is important to put an additional beam in front of an acute angle (indicated by arrows in the figure). These elements also serve as an additional measure of protection during snowfalls, so they are also called anti-snow supports.

The sequence of actions for installing the roof can be briefly described as follows:

1. The rafters from the extension are mounted with the upper trim of the frame.
2. The upper end of the rafters is connected to the purlin, which is pre-installed on the roof or mounted directly on the roof rafters.

Video editing features

NOTE. It is not necessary to connect the rafters of the extension to the house in a rigid way. This can damage the structure due to uneven shrinkage rates of the main room and extension. The optimal solution to this problem is the use of a sliding structure that provides free movement of the lower support.

Roof finishing and insulation

At this stage, the roof is completely finished with its sealing and insulation, as shown in the diagram.

NOTE. If the roof of the extension will simply adjoin the wall of the house, and not organically connect with its roof, then a sealant is used for insulation, tightly closing the hole between the roof and the wall, as shown in the diagram.

Construction and wall insulation

One of last stages- construction of walls and their insulation. The extension is a durable structure, and even if it is used only for household purposes, it is important to create good enough insulation so that temperature changes cannot damage the internal surfaces of the walls and ceiling.

Schematically, the structure of the wall can be represented as follows.

In fact, this is the final stage of the construction itself. Next, the following work should be carried out:

• finishing work inside the extension:
• exterior cladding of the building;
• creating a transition to the house;
• production of windows and doors in the building;
• all necessary communications.

All wooden structures are important to process special solutions, preventing rotting and the harmful effects of temperature extremes.

Timber extension

The principal stages of building an extension (filling the foundation, building walls and installing a roof, followed by insulation and finishing work) do not depend on the choice of a specific construction material. However, depending on it, their own technologies are selected, which differ markedly from each other.

Foundation construction

In the case of an extension from a bar (profiled or round), the differences begin already at the stage of laying the foundation. Since the weight of the future extension will be significantly greater than the weight of the frame counterpart, respectively, the base is required to be more reliable.

A tiled foundation or a pile foundation is often used, less often a tape foundation (for small outbuildings it is quite suitable). In any case, it is necessary that it be settled for at least 1 year.

From the point of view of simplicity and cheaper work, the best option would be to create a pile foundation that can be built independently of the main foundation of the house.

Video - the basics of pile foundation installation technology

Walling

Building walls is quite simple in terms of technology. The only drawback of the beam is that it is quite heavy, and at least two people need to work with it together.

Mounting materials are used as follows:

staples and plates made of metal;

• brackets;
• steel corners;
• screws, screws, nails.

The technology of laying a round beam during the construction of an extension to the house:

Other works

The technology of building walls, insulation and finishing is not fundamentally different from that described earlier.

In the case of building a structure from a bar, two-story structures can be easily made. Of course, in this case, special requirements are placed on the foundation and floors.

Brick outbuilding

Brick extensions to a wooden house are built less frequently. They are great for living, they can also be used as a utility room.

Most often, in such cases, a monolithic foundation is used. At the same time, a brick structure can serve as the basis for the construction of a second floor of the same kind or an attic. Installation of the floor and roof technology does not have fundamental differences from those discussed above.

cinder block extension

And another cheaper and faster option for building an extension to a wooden or other house is from cinder blocks (foam blocks, gas blocks are also used). Such a room can serve as an additional room, but is most often used for household purposes.

The construction of a cinder block structure is very fast due to its large size. building material. This option is great if the owners want to make a garage for a car or an ordinary canopy, a veranda.

And finally - a brief video review of the main stages of the construction of a frame extension to a wooden house.

Such projects are used to increase living space, improve the appearance and expand the basic functionality of the building. At the same time, it is extremely important to study carefully what a high-quality extension to a wooden house is. Projects should be designed taking into account the complexity of their implementation. To do this, you will need to familiarize yourself with the features construction technologies. With the help of this article, making the right decision will be much easier. Go!

Extension to the house: options, photos of successful projects, formulation of general requirements

This photo clearly explains the conventionality of the name. A large extension to a wooden house can significantly improve the original technical and aesthetic characteristics. The main thing is that there are enough sizes for large-scale plans. Of course, we must not forget about the financial and time components of the project.

It should be remembered! It is better to complete the construction of such structures in one warm season. Otherwise, there will be additional costs for winter conservation. Accurate planning will help save money in several stages. In particular, bulk purchases of the necessary basic and finishing materials will be useful.

To build an extension to your own hands, you need to realistically assess your own strengths. The most complex work operations can be entrusted to specialized specialists. But even in this case, your own knowledge will be useful for careful control of the performers.

Note! It is better to hire highly qualified professionals. Slave labor was abolished, among other reasons, due to insufficient efficiency. The involvement of relatives and other dubious assistants may be supplemented by unforeseen additional costs of materials, time and money.

In any case, the target task should be correctly formulated in order to accurately create a set of design documentation. The projects of extensions to the house discussed below will help you make the right decision. In a detailed study, pay attention to the important nuances for yourself. Remember that these examples can be used in various combinations to successfully meet individual needs.

A universal solution to various problems with the extension of a veranda to a wooden house

This is standard definition allows you to make an accurate grouping of different architectural structures. In this case, we are talking about a relatively light construction. Protection of an extension to a wooden house from adverse external influences is designed for the summer season. It does not provide full insulation. However, rain drops and wind penetration are prevented.

How to make an extension of the garage to the house: features of technical premises

Appropriate layers are best placed outside. This prevents the dew point from moving towards the room, prevents moisture from penetrating into the walls. In such places it is better to use foamed polymer plates, which do not need to be additionally protected from water.

The following table provides data that will help you make the correct calculation, taking into account the temperature conditions in a particular region:

Use this information when choosing materials. The final cost of the project depends on many factors. Sometimes it is more profitable to make a large initial investment, but reduce operating costs.

Important! The above examples can be applied in practice if a rigid connection of the foundations is provided. Otherwise, the roof of the extension to the wooden house is made independent of the main structure.

Do-it-yourself construction of an extension to the house: step-by-step instructions with important notes

A photo	How to attach an extension to the house. Main stages of work with comments
	The basis of the project old house with slate roof. The entrance part consisted of a "waiting room", which had dubious aesthetic and insufficient insulating characteristics.
	After inspecting the object, it was decided to build an extension to the wooden house using frame technology. For this lightweight one-story structure, the load capacity of the strip foundation is enough.
	In accordance with the plan, they dig a trench, install	After pouring the building mixture, protruding parts (M12) should remain on the surface. They are useful for a rigid connection with the walls of an extension to a wooden house.
	it is better to do it all at once in order to obtain a uniform structure of the support without seams and internal defects. At the junction with the house, a layer of waterproofing from a roofing material sheet was installed.
	After the mixture has completely solidified, the formwork is carefully removed. The exact time depends on the external temperature conditions, percentage and component parameters.
	Please note that at the stage of preparation for pouring, special pipes are installed for the subsequent laying of electrical cables, plumbing, and other engineering networks. In this project, holes were made in all the walls of the foundation for the space under the wooden floor.
	Not only the contour is concreted, but also separate sites for the installation of supports, a fireplace, and other heavy equipment. Apply a similar technology with reinforcement.
	Support boards are installed through a layer of roofing material on a strip foundation. Their reliable fixation is provided by anchors. Next - mount the ribs of the transverse lags.
	Sewer pipes and other engineering networks are installed under the floor level until free access is blocked to this space.
	Mounted flooring. In this project, the author used a thick moisture resistant. It turned out a solid, even base. For between the lags installed mineral wool, which is protected from water penetration by a film on both sides.
	The frame of the walls is successively installed. Temporary supports are used to maintain the vertical position of these elements.
	Here, the walls are installed on all sides, which creates a closed loop of a full-fledged living space.
	The next step is to install roof structure. The photograph shows that the author delayed the implementation of the project, so the installation had to be moved to winter period. In this case, we are talking only about unfavorable conditions for performing work operations. "Wet" technological processes were completed on time, in the warm season.
	Install the roof structure from ondulin, with a layer of waterproofing. Mineral wool mats are inserted into the cells of the walls, covered with foil. Outside fasten vinyl siding. Inside - lining. Install window and door blocks. Finishing decorative trim perform at their own discretion.

Here it is told about how to make an extension to the house using a frame structure. When using other technologies, the appropriate instructions must be used. Do not forget to make the necessary changes when increasing the loads on the foundation.

Extension to a wooden house: projects of structures from various materials

Some time after construction work, it may be necessary to increase the usable area. A wonderful way out can be the creation of an extension to a wooden house. Projects various structures can be seen in the photo.

Choosing architectural form designs, do not forget about creating a single ensemble in style. Such a structure requires special documentation and permission. Before construction work, it is necessary to study technological features and design options.

It is worth considering the following options for extensions:

• To simple designs applies or dining area. It is used to protect against bad weather and sunlight. Under a canopy, you can have picnics and receive guests. For its construction does not require a strong foundation. Pillars are installed as supporting supports, to which the frame and intended wall surfaces are attached.

Such structures are often built from logs, timber, foam blocks, and also from bricks. Frame technologies are often used.

Extension to the house from the frame: features of design and installation

When making an extension to the house from the frame, significant costs will not be required. This is a budget option. The construction is made on a frame basis, which consists of bars or planks made of metal. After the installation of the frame structure, the walls are clad on both sides. In this case, OSB or chipboard plates are used. Heat-insulating material is laid between the plates. It can be polystyrene foam or mineral wool.

In terms of thermal insulation properties, frame structures are not inferior to more solid stone or brick buildings.

Construction work is carried out in several stages:

“For a frame structure, a foundation is required. You can use a tape construction with waterproofing.

Extension to the house of foam blocks: photos of interesting projects

You can build an extension to the house from foam blocks.

This design is in demand due to the following features:

• The material is available at an affordable price.
• To mount the structure, it is not necessary to mount a complex and expensive foundation.
• The elements hold heat well. This is possible due to the porous structure and low density index.
• Foam blocks are produced in overall dimensions, which affects the speed of construction.

For structures made of foam blocks, a special foundation is required. It can be a tape or monolithic base. Be sure to use high-quality waterproofing. Construction work starts from one selected corner. After installing two rows. This is necessary to ensure better adhesion of the elements.

An extension to a wooden house made of timber: installation nuances and style features

A beautiful and solid extension to a wooden house can be made from a bar. Projects and photos of individual can be found on the Internet.

The material has the following features:

• The production of timber is carried out according to factory technologies.
• The surface is treated with a special composition that protects against fungi and decay processes.
• Naturalness and high environmental friendliness are considered important advantages of the material.

The extension must be connected to an existing building. Usually, the same foundation is made for the structure as for the main building.

For living quarters, a separate foundation and a special wall should be created. The void and the gaps between two walls are blown out mounting foam. This will prevent damage to the wall of the building when the new extension shrinks.

A more economical option for the foundation is pile. The walls are built from profiled timber. After installing the first row, the surface of the tree is treated with antiseptic compounds. Then lags are mounted on it. Voids and cracks are filled with special heat-insulating material.

Each row is fastened with wooden dowels. Particular attention should be paid to the installation of corner zones. For this, logs with a ledge and a groove are used for a stronger grip.

Note! Reinforcement is used to unite the two foundations.

Before proceeding with the construction, one should take into account some of the nuances of installing an additional structure to the main structure. Length new design must be in harmony with the length of the wall of the main construction site. The width of the additional structure can be any.

The extension does not have to be adjacent to the wall where the entrance to the house is located. Exit to a spacious veranda kitchen area maybe from the living room. If a bathroom is planned in an additional structure, then the exit can be made from or. A suitable location for the structure is considered to be the front or end part of the house. The choice and amount of material depends on the type of future structure.

Sometimes it happens that after the construction country house it turns out that he has a small quadrature, or there is a need for separate kitchen, hozbloke, workshop or barn. In this case, you have to make an extension to the house. To reduce material costs to a minimum, you should immediately think about what to build it from.

How to build an extension to the house with minimal costs, with photos and examples, how to prepare the foundation for it, what material to choose for the walls and roof - later in the article.

general information

In the event that water supply and sewerage are planned in the extension, as in the case of the construction of a kitchen or bathrooms, this issue should be puzzled before pouring the foundation.

If you plan to use the extension not only in summer time, then it is necessary to provide for floor insulation, for example, with the help of expanded clay bedding. It is also useful to think over in the case of living in winter how to heat the room.

As an easy extension option, you can equip a veranda - it provides protection from wind and bad weather. In winter, it will not be possible to live on the veranda, since, as a rule, it is not heated.

The extension must be in harmony with the main structure. An economical, warm and prefabricated version of the building is a frame made of wood, after erection it is easy to finish it under the main building. It has many advantages:

• simplicity and speed of construction;
• relative cheapness;
• environmental cleanliness of the extension;
• there is no need to build a capital foundation.

Foundation construction

For a veranda or residential extension of a frame type, a columnar foundation is suitable, since the weight of the structure is small. If there is a need to bring communications, as is the case with a bathroom or kitchen, it is necessary to ensure thermal insulation of the water supply and sewerage sections located on the street. This will cost a pretty penny, but the costs are much less than if it were necessary to equip a strip foundation. The floors in such an extension are made of boards so as not to burden the structure.

The concrete pillars on which the structure will stand are poured 50x50 cm in size at a distance of 1.5 meters from each other. The bottom of the pits under the pillars is covered with a layer of sand, then with rubble, and all this is carefully rammed.

Pillars must be reinforced to give strength to the foundation. The formwork is removed about a week after pouring, when the concrete has gained strength. As a waterproofing, bitumen or roofing material is glued to the poles.

Bottom trim and floors

In order for the frame extension to serve for a long time, it is necessary to provide waterproofing and impregnate all wooden elements with an antiseptic and fungicidal composition. High-quality waterproofing gives bituminous mastic.

A 150x150 mm timber is used as the lower trim, preferably from larch. Under it, a roofing material is necessarily planted to isolate it from the foundation. The first row is laid strictly horizontally in level, without connecting the timber at the joints.

The second row is laid with overlapping joints on the first. Then, with the help of studs, the first and second rows are connected. You can use 50x150 mm boards instead of timber, and in order to achieve structural integrity, they are connected to self-tapping screws.

The lower harness is attached to the beds, on which the logs are laid. Insulation is placed between the lags, for example, polystyrene, and subfloors are laid. Finishing floors are laid from moisture-resistant plywood.

Walls

The walls are made in two ways - either they assemble the structure on the ground, and then erect it, or gradually build the frame in place. For the first option, several people are needed, since the structure cannot be lifted alone.

The erection process begins with corner posts, it is very important to maintain right angles in all planes. For racks, a bar with a section of at least 100x100 mm is used. The pillars are placed at a distance slightly narrower than the width of the insulation sheet.

Openings for windows and doors are equipped with additional pillars and crossbars. The top of the frame is fastened with an upper strapping of the same design as the lower one. Sheathing is carried out with OSB, siding, plywood, clapboard.

Roof and insulation of the extension

The roof is easiest to equip with an ordinary shed. It should be done as a continuation of the roof of the main building. This is possible if the extension to the house is side. The roof of the extension must go under the main roof.

All elements - rafters, beams, crate must pass with an antiseptic. The roof is overlapped and, depending on its type, is attached to the crate with self-tapping screws or slate nails.

Styrofoam or mineral wool is used as insulation. First, the frame is sheathed with a hydrobarrier, then an insulating material is placed between the racks of the frame, and a vapor barrier is attached between it and the lining. Then they attach OSB or drywall to the racks, and proceed to the fine finish.

Photos of extensions to the house

In order for the house to have a more original appearance very often they use additional building elements - extensions that will allow you to spend your leisure time or gather a family at a large dining table. An extension can be created at the stage of building a house or upon its completion. Also, very often a veranda, terrace or other type of extension is already used for houses that were built a long time ago. In this case, you will have to think about how to protect the additional room from the influences of nature, its whims in the form of snow or rain.

The roof of such a structure should adjoin the house, have a certain angle of inclination so that precipitation does not accumulate on its surface. For a long service life of the extension roof, you must carefully follow all the rules and conditions, choose the best material for the roof.

Types of roofs and types of roofs

A well-thought-out exterior of a private house will create a pleasant impression, both for the owner of the home, and for his friends or neighbors, because according to the external perception of the house, an opinion is formed about its owner. Ideally, the design of the house and extensions should match each other, properly combined with each other.
In order for this to become possible, it is necessary to use a single roofing material, both for the house and for an extension to it. An exception to the rule will be glass extensions for dining table overlooking the environment or the greenhouse. In this case, the roof must also have a transparent appearance, regardless of the house and its covering.
It is necessary to understand the specifics of the words, to understand their essence, since the roof is the upper part of the house, a structure that has layers of thermal insulation and waterproofing. In turn, the roof decorative coating protecting the roof from atmospheric precipitation.


Choice roofing materials for an extension depends on several factors:

• The functional role of the room.
• Extension architecture.
• Building materials used in building a house.
• Roofing roof materials.
• financial opportunities.

If it is impossible to use a single roofing material, then you need to think about how it will look externally, what is appropriate in this case and what is not. It is important to keep the house and the extension in the same style so that the extension does not seem superfluous. Ideally, an additional structure should emphasize the house, be its original decoration. If you think over the project well, you can create such an effect that it will seem as if the roof of a private house “flows” onto a terrace or veranda, thus forming one whole.

Roof types:

• Flat.
• Pitched (the name depends on the number of slopes)
• Single and multi-stage.
• Domed and conical.
• Complex (broken line, multi-forceps, etc.)
• Ceiling and attic.

A complex roof is used only for extensions that must match the style of the house, for example, classicism or Gothic style. In general, more popular for outbuildings is simple shed roof, because it will be the best, practical and inexpensive option.
A shed roof can be built using various methods, but initially you need to determine:

• Construction of an additional building.
• roofing material used.
• Roof features.
• What will be the layers of thermal insulation and waterproofing.
• Financial opportunities.

The choice of material for the roof of the extension

Before buying the first roofing material that comes across, you need to view their complete list, find out the advantages and disadvantages of each individual material taken. After comparing all the pros and cons, you can choose best option what will be used for the extension is ideal if it is similar to the material used for the roof of the roof of the house.
Previously, the choice of roofing materials was limited, but now in the 21st century the range is practically unlimited, neither in terms of flexibility, nor in color or other factors.

Popular roofing materials:

• Fastlock.
• Soft roof.
• All variations of tiles.
• Slate.
• Decking or metal roofing.
• Expensive decorative roofing.

Things to consider when choosing a roof:

• Required amount of materials.
• Lifetime.
• The price of the material, the cost of its installation.
• Plasticity, flexibility.
• Weight and resistance to external factors.
• Fire safety.
• Color variability.

The nuances of laying the roof

A simple extension option is a covered terrace or veranda. In this case, the main role is played by the foundation and the roof of the extension. The extension itself can be both closed and open, the main thing is that this is a place to relax, where there should be no cold and moisture.
It is necessary to determine the angle of inclination - in the optimal case, it should be 20-30 degrees, if less, then snow will accumulate on the roof surface, if more, then the roof will be subject to large wind loads.
During construction truss system you need to take into account all the subtleties and nuances, use boards and bars sufficient thickness. The rafters are fixed with self-tapping screws or anchor wedges (depending on the material to which they are attached). With the correct construction of the truss system, the roof must have a margin of safety that can withstand a hurricane or tornado, regardless of whether they happen in this region or not.
If the extension is not residential and has a “cold” roof, then heaters will not be needed here. If you plan to build a large residential building, then you can use gable roof, and the attic should have a triangular shape. Special attention thermal insulation and waterproofing should be given, because cold and moisture are unacceptable here.

Stages of installing a roof for an extension

For example, you can take the simplest, but at the same time a popular option for extensions - a shed roof with ordinary rafters and roofing cake from slate.

• Carrying out calculations, development of drawings. At this stage, the angle of inclination of the roof is determined, it should be from 20 to 35 degrees.
• On the edge of the extension, we install a beam, the stop point of the roof structure. Further, every 0.8-1 meters we mark places for installing rafters. A special beam is fixed with anchor wedges to the lower beam and the upper harness. Then, the extreme rafters are placed on the beam, after which the rest are set along the lace to the previously marked points.
• Installation of waterproofing.
• Lathing installation.
• Laying a layer of insulation between the rafters and the crate.
• Sew up the rafters with plywood or a wooden shield.
• Laying slate according to the technology prescribed in the instructions.
