Installation of ondulin on a gable roof. How to cover the roof with ondulin with your own hands

Laying ondulin is one of the most common ways to design a roof.

This is due to the fact that ondulin combines the most attractive qualities of roofing - low cost, ease of installation and noble appearance.

The use of ondulin is a universal option for both suburban private houses and low-rise residential and non-residential buildings.

In order to correctly approach the choice of material and its installation, it is proposed to study the useful information in the article.

What is ondulin?

Ondulin (euro slate) is a lightweight and durable roofing material made of cellulose pulp, bitumen, hardening resins and various fillers.

Cellulose and bitumen undergo deep cleaning before manufacturing. Euroslate was invented in France only half a century ago.

Ondulin is offered in the form of corrugated sheets with a high degree of protection against the effects of adverse natural factors.

The material is lighter than conventional slate, so laying it is much easier and faster. The method of production and the composition of ondulin directly affect the properties roofing material.

Advantages of using ondulin:

• low cost due to the production method and the availability of manufacturing materials;
• lightness, due to which it is not required to design a reinforced truss system before putting ondulin;
• easy care and cleaning - you can pour from a hose or wait for heavy rain;
• material does not chemically react with large quantity acid, alkali and petrochemical irritants;
• the formation of mold and fungus is excluded;
• environmentally friendly and safe material due to its composition;
• resistant to precipitation;
• service life will be 15 - 20 years;
• installation of ondulin can be carried out on the old roofing, while saving on dismantling.

It is worth mentioning the shortcomings of the material in order to ensure the objectivity of the choice of roofing:

• over time, ondulin fades under the sun, which will negatively affect general view Houses;
• the guarantee for hydrophobicity extends only during the period specified by the manufacturer;
• when buying a large amount of material, a color mismatch is possible, bitumen stains may appear on the sheets;
• you can’t walk on the roof with an ondulin coating, as dents and damage will definitely remain. Care will be required during transportation, lifting and installation;
• exists only in 4 color options: green, brown, black and red;
• when wet, the material does not hold its shape well, so the crate should be even and in the same plane.

All the pros and cons of the material indicate that the choice of it as a roof covering should be carefully considered.

Roof device features

Before attaching ondulin, you need to familiarize yourself with the recommended composition of the roofing cake, which is suitable for this type of coating.

Due to the lightness of the material used in the construction of the truss structure, reinforcing elements can be dispensed with.

The coverage will consist of the following parts:

• rafter system of any complexity;
• insulation;
• vapor barrier;
• waterproofing;
• counterlattice;
• crate.

The crate is fastened to the rafter legs made of natural beams, the cross section of which and the installation step are calculated in accordance with the region of residence.

Before installing the ondulin coating, a heat-insulating layer is laid, calculated in accordance with the norms of the region of residence.

As a heater, glass wool, basalt wool or expanded polystyrene are usually used. The heat insulator is placed in blocks between rafter legs.

The step-by-step instruction for laying a roofing pie involves the use of a vapor barrier layer, which will protect the heat-insulating layer from below from moisture and steam penetration.

To protect the rafter system, battens and heat-insulating layer from the occurrence of condensate, a waterproofing layer is applied.

The waterproofing material is attached to the rafter legs from above with a construction stapler.

Before installing the roof covering on the waterproofing layer, wooden planks are laid along the rafter legs to create a small space in which air will circulate.

Ondulin is placed on a crate made of even boards laid in the same plane with a step of 45 - 60 centimeters. The longitudinal crate is attached to the counter-crate.

The short spacing between the battens is due to the tendency of the material to warp when wet, which requires good support.

The roofing material itself is attached to the crate with special nails, the color of the caps of which is selected according to the color of the sheets. The technology of laying ondulin assumes the presence of an overlap of sheets of 15 - 20 centimeters.

Before laying the roofing cake, the wooden frame in without fail treated with antiseptic and refractory solutions.

Installation of ondulin coating

Installation of a roof covering includes preparation for installation and installation itself.

Do-it-yourself ondulin laying is performed at a certain temperature.

The best temperature conditions are considered to be the range from 0 to 30 degrees Celsius: if the material is installed in frost, the ondulin will become brittle and crumble from mechanical stress, and if the installation is carried out at very high temperatures, then it is likely that the sheets are deformed from heating.

When laying the material at temperatures close to the maximum allowable, it is necessary to observe the original shape of the euroslate.

If ondulin stretches during installation, then when frost sets in, it will decrease in size due to physical properties. Such a process will lead to damage to the roof.

When installing the coating, you will need to cut the material. This is done with a hand saw lubricated in advance with oil, or with a grinder, which will require additional effort and caution.

Before installation work, you need to prepare special fastening nails in advance. About 20 nails are used for each sheet: half of them are attached to the lower part of the sheet, ¼ goes to the middle part, the remaining quarter to the upper part.

The step of the crate depends on the slope of the slope on which you need to put the ondulin. Slopes up to 10 degrees are equipped with a continuous crate of plywood or boards.

With a slope of 10 - 15 degrees, the crate is laid in increments of 45 centimeters. If the angle of inclination is higher than 15 degrees, then the step increases to 60 centimeters.

Mounting process

Work begins on the ground, cutting sheets of material to the required dimensions. After that, observing the rules for laying ondulin and precautions, the sheets are superimposed on the crate in the direction from bottom to top from the leeward side of the roof.

The initial sheet is aligned strictly with respect to the lines of the cornice and the end of the slope. Ondulin should not protrude beyond the eaves by more than five centimeters.

The arrangement of sheets in a checkerboard pattern implies horizontal and vertical overlaps between the sheets. In this case, be sure to constantly check the level of laying sheets.

When performing overlaps, the following requirements must be observed:

• at an angle of inclination of the slope, the value of which is not higher than 10 degrees, the vertical overlap is no more than two “waves” of the sheet, the horizontal one is at least 20 centimeters;
• when the slope angle is 10 - 15 degrees, the overlap level is reduced to one "wave" vertically and 17 centimeters in the horizontal plane;
• one "wave" of overlap in the vertical plane is maintained when the slope is more than 15 degrees. The horizontal overlap is reduced to 15 centimeters.

Fasteners should be installed strictly according to the instructions for the material. Special nails with protective caps are hammered into the lower crest of the “wave” according to the markup.

Observing a certain sequence, how to properly lay ondulin, the final stage cannot do without installing additional decorative and protective elements.

To install an ondulin valley, you will need an additional crate. The valley is installed under sheets of roofing material.

The fastening of the ridge decoration starts from the leeward side, the overlap on the sheets is at least 13 centimeters.

Nails are attached to each lower “wave” of the sheet in additional laths of the crate installed in advance.

The design of the end joint of the roof with the wall is carried out by a valley, which is thoroughly sealed with silicone.

For competent design of the sides of the overhangs, gable or ridge parts for ondulin are used.

Choosing ondulin as a roofing, we can conclude that it is cheap and reliable material but for a certain period of time.

Laying can be done both independently, to your taste, and entrusting this task to specialists.

With proper installation, you can be sure of the comfort and warmth that a new roof will provide.

There are many types of roofing materials available today. However, not all materials meet the set requirements and have high quality indicators. Euroslate gained popularity in the construction market in a matter of years for a reason, but one way or another, its popularity has deteriorated somewhat due to the emergence of serious competition. Nevertheless, laying ondulin can be done on top of the old coating without dismantling it, and this is worth a lot.

Positive and negative sides of ondulin

Before talking about how to lay ondulin, you need to understand the properties of this material.

Euroslate is used exclusively in private construction. This material is a wavy sheet, in appearance resembling ordinary asbestos slate. The composition of the sheet includes natural cellulose, modified bitumen and other components that increase the waterproofing qualities of the product.

Advantages of ondulin.

• Good waterproofing performance. This property achieved by a combination of the right components that make up the product. Natural cellulose fibers are laid in such a way that water cannot pass through them, not to mention the main insulating component in the face of bitumen. Ondulin can withstand a large amount of moisture and at the same time not change its geometric parameters, although there are enough fakes on the construction market.
• Good resistance to temperature changes. The laid sheets of euroslate are not afraid of heat and cold. When creating a quality foundation, they will not deform in any way.
• Resistance to chemical and biological activity. Special additives protect the material almost 100%. On the roof of euroslate you will never notice any mold or fungi. As for alkalis, oils and acids, the surface simply does not enter into any reactions with them.
• The biggest advantage of this product can be considered light weight. Due to this, installation work can be carried out independently, without any partners. In addition, it is allowed to put ondulin on the roof over the old coating, without dismantling it. This feature will significantly reduce the cost of updating roofing. It is worth noting that before such a procedure, it is worth recalculating the maximum load on the roof, since for attaching the sheets it will be necessary to knock down the base.

Cons euroslate.

• Work on the installation of bituminous materials on the roofing surface is strictly limited by the weather. As you know, the material contains a large amount of bitumen. Interacting with low temperature, the sheet becomes very brittle and can easily break at the slightest deformation. As for the heat, the bitumen begins to show excessive elasticity and may even flow along the crate.

• The second major drawback is the fast loss of color contrast. The surface of the sheet does not have any protective layer that could reduce the effect of sunlight, therefore, after a short period of time, color loss will begin. For some residents, this can become a serious problem, while others simply do not pay attention to it.
• Rough surface will not allow precipitation in winter time year to be removed naturally, therefore it is necessary to create roofing systems with as much slope as possible.
• High degree of ignition. According to this paragraph, such a coating cannot be laid on the roofs of public buildings, which is why the material can only be found in private construction.

It is worth noting that ondulin roofing refers to a soft roof and a solid crate is suitable for laying. But due to the fact that the sheet has good rigidity, it can still be attached to a discharged base, but with a minimum step.

Installation nuances

For any roofing works Ah, there are certain nuances. Some materials are best not stacked with others, or only boards can be used to create the crate. Now we will discuss all these points in more detail, and you will understand how to properly put ondulin on the roof.

Laying ondulin on the roof should be carried out according to some technology, but at the same time there are nuances that cannot be ignored, especially the question of “how to mount ondulin on the roof?”

Suitable weather conditions must be chosen for installation work. You already know that at low temperatures euroslate sheets begin to crumble, and at extreme heat they just melt. The optimal value of the thermometer should be in the range from plus 10 to plus 25, only then can the coating be laid without any structural deformations.

In addition, this material should not be laid in the rain. If the construction is carried out from scratch, then close the wet roofing cake, it's like using bricks as a foundation for a heavy house. When it rains, all the lumber will get wet and part of the protective impregnations will leave them, in addition, moisture will remain in the attic for a long time, since the coating will not allow it to go outside.

When mounting the sheets, do not try to stretch them. Similar actions often committed by unscrupulous hired roofers. They try to stretch the canvas of the sheet as much as possible in order to increase its working area, of course, it makes no sense to do this with small volumes, but when the area goes beyond 200 squares, then there is something to profit from.

By stretching the sheets, workers can get the job done faster and at the same time save a couple of sheets that will successfully leave with them at the end of the working day. Fooled in this way, the owner is waiting for an expensive repair to replace the roofing sheet next spring, since all the sheets laid will crack at sub-zero temperatures.

If during the laying process it became necessary to divide the material into some parts, then it is best to do this with an ordinary hacksaw. For speed of work and easy cutting, its blade is lubricated with oil. When handling power tools, be careful, the material is very flammable and sustains combustion for a long time.

Before laying ondulin on the roof, you will have to acquire special fasteners. They can come with euroslate sheets or they will have to be purchased separately. Mounting ondulin on the roof is carried out using special screws or nails. The consumption of fasteners per sheet is about 20 pieces. It is best to arrange them as follows: half goes to the bottom of the sheet, part to the middle and the rest are placed on top. By the way, the ondulin mount is available in different colors, so to improve the aesthetic properties of the surface, it is better to choose the right tone.

The base will depend on the roof slope. If the slope is less than 10 degrees, then you need to knock down a continuous crate. It is made up of two layers. A bar or board is used as the main elements of the first layer. OSB boards or moisture-resistant plywood are laid on top of them. Some developers fill the boards, but I do not advise doing this. The resulting plane will not be even, and the curvature of the base will significantly affect the duration of operation of such a roof. An exception may be a calibrated board, where all dimensions are adjusted to one value.

In the case when the slope is in the range from 10 to 15 degrees, then you can slightly defuse the crate. Stick to a maximum step of 30 centimeters. With such a slope, this is quite enough to transfer all temporary loads. If the slope of the slope is more than 15 degrees, then the step can be taken even more: up to 45 centimeters.

IMPORTANT: When laying the discharged base under the euroslate sheets, all important places are still equipped with a continuous crate. These include the valley, ridge and cornice knot.

Now, let's move on to the next point, and consider how ondulin is laid by hand.

Laying ondulin: instruction

If you want to install the coating yourself, but do not know how to lay ondulin on the surface, then this item is for you.

When purchasing roofing material, carefully study its qualities. Ask the seller about the company and delivery this product to its warehouse, storage conditions and the like. Due to the loss of popularity, it may turn out that euroslate has been in the warehouse for a long time, therefore, it may lose some of the qualities that are important to you.

If you are working with this material for the first time and do not know how to fix ondulin, then remember laying ordinary slate. With zero construction, there will be absolutely no difference here.

Instructions: how to properly put ondulin on the roof.

• You can start laying ondulin from any side. The first sheet is placed along the edge, taking into account the gable and cornice overhang. You already know how to properly attach ondulin, so I don’t see the point in focusing on this. The only thing to say is that all sheets are overlapped, the value of which is taken based on the slope. The optimal value of the vertical overlap lies in the range from 15 to 30 centimeters. As for the horizontal, it is 1-2 waves.
• After laying the first sheet, proceed to the installation of the second. Fill in the row in the same way.
• At the beginning of the second row, half of the sheet, cut along, is laid. This is done in order to separate the seams and increase the tightness of the entire plane. The cut edge is hidden under the overlap and never laid in the direction of the pediment.
• Thus, alternating whole and cut material, the slopes are filled.
• After that, additional elements are installed and the building is put into operation.

If you don’t understand something, then watch a video on how ondulin is laid on the roof:

Before laying the coating, you need to take care of creating a high-quality roofing pie. It should include the following materials:

• Hydro insulating material. It would seem that the roofing will ideally protect all the underlying elements, but everything is not so simple. Humid air enters the attic not only from the outside, but also from the inside. During human activity, liquid is ejected, which rises and concentrates in the attic.
• Thermal insulation. Despite the solid thickness of the sheet, it has a high thermal conductivity, therefore, all heat will fly away through it.
• Litter. Some developers use underlayment when laying soft roofing products. It levels the surface and creates another layer of insulation.

As you can see, everyone can create a roof from euroslate, the main thing is to choose high-quality materials.

Construction or overhaul buildings requires significant material investments, most domestic developers are looking for various ways to save money. Modern building materials and technologies can significantly reduce the estimated cost of work and at the same time obtain high-quality houses with a long service life.

Developers are offered a huge range of materials for building walls, finishing their external and internal surfaces, arranging floors and ceilings. There are budget materials for roofing, among them ondulin occupies a special place. Technical specifications of this material have a significant impact on the installation algorithm, knowledge of the characteristics will help to avoid annoying mistakes.

It is impossible to describe all the possible situations encountered during the installation of the roof. There is only one way out - to carefully study the technical and performance characteristics ondulin and on the basis of this knowledge independently make a decision during roofing work.

Ondulin is considered a cheap option for roofing roofs, the quality is the same. It is not used to cover prestigious buildings, it is often used as a temporary roof.

Due to the low strength of ondulin during long-term storage or transportation, the geometry of the sheets is broken, which significantly complicates the installation process: it is difficult to align the sheets, the waves are not the same, the ridges can mix, etc.

Recently, the most responsible manufacturers have been releasing new DIY and SMART models, they have smart locks that increase the tightness of coatings.

For constant control of the position of the sheets and to facilitate the selection of fixation points on the surface, there is a factory marking. The locks are two convex strips with a width of approximately 15 mm each, which makes it possible to precisely align the sheets, control their position and completely exclude the ingress of water or snow in the overlap areas. The cornice overhang is even, all sheets lie on the slopes exactly in parallel lines. Another plus of the grooves is that the recommended amount of overlap is reduced, thereby increasing the usable area of ​​the sheets.

Prices for various types of ondulin

The laying technology does not belong to the category of particularly complex, the material is easily cut, fixed with nails, due to the presence of special elements, the sheets are easily leveled over the entire area of ​​​​the slope. But experienced craftsmen have their secrets.

What you need to know before you start styling?

When purchasing ondulin, be sure to ask for installation instructions and carefully follow all manufacturer's recommendations. Remember that this manual is also a warranty card. True, in practice, there are still no cases of a positive resolution of consumer complaints about the inappropriate quality of the roof. The document has definitions of all additional elements, advice on the proper arrangement of chimney pipe bypasses, sealing of valleys, fixing sheets in places of cornices and side junctions.

It is possible to start work only after materials and additional elements have been purchased, fixtures have been prepared, there are tools, and a drainage system layout has been drawn up. It is necessary to cover the roof as quickly as possible, any technical delays increase the risks of worsening weather conditions. And this always has extremely negative consequences.

Another important point – check the weather forecast for roofing work. At the same time, keep in mind that for ondulin, the problem is not only rain, as for roofing with other materials. It is forbidden to work with it at an air temperature of more than + 30 ° C. Avoid prolonged heating of sheets with straight sunbeams. Ondulin is most often of dark shades, the sun quickly heats the surface to high temperatures, the material not only loses its physical strength, but also changes its linear dimensions and geometric shape. You can not lay ondulin and at temperatures below -5 ° C.

For marking, use a colored pencil or marker, and replace an ordinary flat ruler with a cut sheet with one even factory edge. With it, you can draw a solid line on the waves of ondulin and constantly control the quality of cutting. But you should not waste a lot of time following this recommendation, inaccuracies during marking or cutting within 1-2 cm are not considered critical. The fact is that the cut edges according to the installation technology are always overlapped with additional elements, their dimensions cover all the irregularities.

It is recommended to cut ondulin with an ordinary wood saw with fine teeth; for better glide, the canvas must be periodically moistened with water. As practice shows, the use of various electrical tools does not give any positive results. The speed and accuracy of cutting remain the same as when working with a hand saw, but there are additional problems. It is necessary to have extension cords, to keep track of the position of electrical cables, etc., and this is difficult to do on the roof. Along the waves, the material is perfectly cut with a simple construction knife.

Each sheet should be nailed with at least twenty nails. This rule must be strictly observed. Ondulin soft material, an insufficient number of fixation points causes its deformation, violation of linearity, bending of the edges. Another problem is that the risks of undermining the coating by strong gusts of wind increase. Most companies designate fixation points on the front surface, follow the manufacturer's recommendations.

First, the extreme nails are nailed, due to this, the stretching of the soft sheet is prevented. Then, in turn, in a checkerboard pattern, all the others are fixed. You need to score carefully, the hats should not push through the sheets. But you can’t leave gaps either, the ondulin will move a little and increase the diameter of the inlets, leaks may appear in these places. The nail enters the crate at a right angle. If the tip does not hit the tree, then it is allowed to slightly tilt the body of the hardware, do not worry that water will enter through a small gap. First, the probability of a drop falling exactly into this slot is small. Secondly, there are never significant flows of water on the crest of a wave. Thirdly, if a few drops get under the roof, they will dry quickly and will not harm the truss system of the house.

Sheets on slopes must be laid with offset rows, due to this technology, four corners are not concentrated in one place.

A large number of corners raises the places of overlap, the roof becomes uneven, and the likelihood of water or snow getting into the cracks increases. To offset, each even row must be laid from half the sheet. Installation starts from the bottom rows. If there is a need to move through the stacked sheets, then this should be done very carefully. You should step on several ridges at once, if the ondulin is very hot, then it is recommended to use special devices. How they are done, we will describe below.

When choosing a material for roofing, the building materials market offers enough options, among which you can choose classic coatings that have proven their strength over centuries of operation, or you can turn to modern coatings that also have good performance and have managed to prove the expediency of their use. Such modern roofing material as ondulin is in particular demand, the installation instructions for which are attached when purchasing the kit. By following the instructions exactly, it is quite possible to cope with the installation of an ondulin roof on your own, even with minimal skills in performing construction work.

For a complete picture of ondulin, you should first of all know that it is an environmentally friendly roofing material made using modern technologies. The basis for the creation of ondulin are cellulose fiber and mineral fillers. In the process of its production, thermosetting resin and distilled bitumen are used to impregnate the manufactured sheets. After impregnation with bitumen, the finished sheets of material are painted.

Ondulin is produced in two types - slate and tile. In terms of quality, both materials do not differ, ondulin differs in sheet size - 2000 x 950 mm, called slate and tiles, produced in smaller sizes, used in the case when an ondulin roof of complex configuration is installed. The use of tiles in this case reduces the amount of waste. Ondulin slate is used to cover roofs of a simple design.

Ondulin has many advantages - environmental friendliness, resistance to external influences, including atmospheric, light weight and low cost of installation of the product, as well as the ability to install ondulin with your own hands. The main disadvantage of the material is its combustibility, but this property is significantly reduced by processing ondulin with a special composition during manufacture.

When carrying out the installation of a roof made of ondulin, strict adherence to the installation instructions, which carefully take into account the characteristics of the material, is necessary. To obtain a high-quality roof for a constructed building, all the recommendations given below. must be carried out without fail.

The use of ondulin in the repair of roofs

When the roof of the building becomes unusable, then with the help of Ondulin, you can quickly repair its individual sections, which will perfectly perform their functions. However the best option will be a complete replacement of all roofing material with a new one. The use of Ondulin slate also provides for a less radical solution - the installation of a new coating without removing the old one, laying a new layer of roofing on top.
This is possible due to the light weight of euroslate sheets, which allows the use of this roof repair technology.

The advantages of ondulin as a material for installation and repair of roofs

Using Ondulin will allow you to build a high-quality roof in the shortest possible time. By choosing the installation of a roof from ondulin, the owner of the house will have the opportunity to long years do not worry about the condition of the coating

The use of Ondulin will provide the owner of the house with:

1. obvious savings in the repair of the roof, the use of Ondulin does not require the removal of the old roof;
2. Availability detailed instructions makes it possible to carry out the installation of Ondulin with your own hands;
3. there is no risk of moisture penetration during repairs, since the old coating is not opened;
4. the use of the old coating, when installing a new layer of Ondulin, improves the thermal insulation of the roof;
5. getting excellent appearance material, the choice of color of the roofing.

The main stages of roof repair using ondulin

Repair of roofs with the use of high quality roofing, known as "Euroslate", or Ondulina, is divided into the stage of preparation for installation and the installation stage.

First of all, the condition of the old coating is checked - the ventilation system, insulating material. If there are malfunctions, they are eliminated.

With increased fragility of the old material, the crate is installed by drilling and fastening to self-tapping screws. When planning the installation of additional insulation, a gap under the crate is provided for it. To protect against condensate, the insulation is covered with an Ondutis SA 130 membrane, and an Ondutis R 70 vapor barrier film is fixed over the crate.

When performing the crate, in order to mount the roof from ondulin, a beam is used, the cross section of which corresponds to the size of the euroslate wave. An additional crate is required to install and fasten the ridge and valley.

When erecting a roof or carrying out its repair using ondulin material, the instructions for installing the roofing must be followed exactly, only then it will last for many years without requiring repair.

One of the most popular ways of arranging roofing in private housing construction is laying sheets of roofing ondulin. Taking into account the specifics of this modern French roofing material, the technology of its laying has a certain number of features, taking into account which allows you to get a high-quality and durable roof.

Mounting options and methods

In today's market building materials roofing from refers to the most advanced roofing systems that are widely used around the world. Today, there are several options and methods for installing this inexpensive, but high-quality roofing material.

On the old roof

A significant advantage of ondulin is that there is no need to dismantle the old roof covering. It is enough just to mount the insulation layer, on which the roofing sheets are laid in accordance with the same technology as in the process of installing a new roofing.

Stages of laying on the old roof:

• pulling the rope along the lower segment of the bars and aligning the remaining vertical bars along it, installed at a distance of every fifth wave of wave roofing material or after 60 centimeters;

• fastening the vapor barrier across the slopes using mounting brackets in increments of 15 centimeters, followed by gluing the joints with mounting tape;

• installation of a horizontal bar flush with the ends of the vertical lathing and fastening at the points of intersection with vertical bars with 70 mm self-tapping screws;

• to provide the places of layering of two sheets of the old coating with a cut at the level of the horizontal crate;

• laying thermal insulation and breathable membrane;

• laying ondulin from a section of the roof opposite to the prevailing wind.

For roofing material

It is allowed to mount onduline sheets on the surface of the old roofing felt, in this case, all breaks in the old coating should be eliminated. For high-quality installation, it is necessary to install a new counter-lattice along the length of the rafters and the batten across the rafter system. Such work will allow condensate or trapped moisture not to stagnate on the roofing material. A beam with a section of 5x5 centimeters is used.

The counter-lattice is placed with an interval of rafters, and the crate is installed in increments of 60 centimeters. Further, all work on laying ondulin sheets is carried out in accordance with the attached instructions.

new roof

When created from sheet ondulin new roof it is necessary to pre-lay a high-quality crate at intervals according to the angle of inclination of the slopes. After completing the crate, you should carefully mark the sheets of ondulin. To cut marked roofing material, a wood saw is most often used, which is pre-treated for high-quality sliding with oil.

During installation, the following basic requirements must be observed:

• the starting row of sheets should be fixed on the opposite side from the wind blowing;
• the next row of sheets is attached from half of the previous one;
• sheets should be fixed for each wave.

Do-it-yourself laying rules and technology

• For continuous lathing, used with a slight slope, moisture-resistant sheet lumber or thin tongue-and-groove boards are used. The maximum gap between such materials should not exceed five centimeters.

• For slopes with average slopes, a thinned crate is required with a distance between elements of 45 centimeters.

• For a roof with a significant pitched slope, it is necessary to install a thinned type of lathing in increments of 60 centimeters.

Scheme and instructions for mounting ondulin on the roof

According to the correct execution of installation work, ondulin is applied by the manufacturer to each manufactured product. Main stages self installation roofs from sheet ondulin are as follows:

• to facilitate installation work, ondulin start sheets should be attached to the edge of the roof opposite the leeward side. The second row begins with half a sheet of the first row, which forms three sheets at the corner joint;

• fasteners are driven into each wave at the end segment and overlap of the sheet, as well as on both sides of the side overlap. Fastening to intermediate crate bars is made through a wave. Twenty roofing nails are used per sheet;

• installation of the ridge elements begins from the edge of the roof opposite to the leeward side using an overlap of 12.5 centimeters. The place of fastening of the ridge elements is the wave of the roofing sheet that joins the ridge and additional crate bars;

• it is necessary to mount the valleys, gable elements, as well as correctly arrange the side roofing joints at the junction with vertical surfaces by means of a covering apron;

• mounting ventilation system involves the use of a roof fan, ventilation pipe and a special comb;

• in order to arrange an exit to the roofing surface and organize the lighting of the attic space, it is required to mount a roof window, which is attached to each wave of the sheet at the junction. By means of the top sheet, an overlap is made on the base of the roof window;

• to perform high-quality waterproofing of the joints of the roofing surface with vertical surfaces, it is recommended to use Onduflash insulating tape.

For more information about laying with your own hands, see the video.

roofing cost

Despite the fact that sheet ondulin roofing is easy to install on your own, many homeowners prefer to use the services of professional craftsmen who not only perform this type of roofing work quickly and efficiently, but also provide a guarantee for all work performed.

The average price of "TURNKEY" roofing works, excluding the cost of ondulin, depends on the volume and type of work performed:

• without dismantling the old roof, including cleaning the roof, installing a counter-lattice and step lathing, as well as laying a roofing ondulin, ridge, wind and cornice strips and a chimney - 400 rubles per square meter;

• instead of the old roof with the strengthening and repair of the rafter system, including the dismantling of the roofing carpet of the old coating, the strengthening and repair of the truss system, the installation of ondulin with waterproofing, as well as all accessories - 800 rubles per square meter;

• a complete roofing pie from mauelrat, including insulation, windproofing, waterproofing, vapor barrier and internal filing with the installation of ondulin - 1200 per square meter.
