Ondulin is a modern material with good performance and quality. Perfectly suitable for the arrangement of the roof of private houses. At a relatively low cost, the ondulin copes with all the tasks assigned to it. At the same time, the installation of the onduline roof can be done manually.
Ondulin is environmentally friendly material, which is used in the manufacture of modern technological achievements.
At the base of the onduline leaf is cellulose and various additives. To provide the roofing with the required indicators of water resistance and rigidity, it is treated with special materials - bitumen and resin, which have undergone preliminary treatment.
Finished onduline sheets are painted with special compositions that provide an excellent appearance of the material and contribute to improving its performance properties.
Externally, the ondulin can have the form of metal roof tiles or slate. The quality of the roof is not different. Sheets under the "slate" are produced in the amount of 200x95 cm. "Tile" also has a reduced size. Material in the form of tiles are better suited for roofs with a complex configuration - it is simply more profitable, because the volume of waste is reduced to a minimum.
Ondulin in the form of slate is optimally suited for simple roofing structures. Such sheets are easier to install and allow you to do the work in the shortest possible time.
Advantages and disadvantages of ondulin
Ondulin perfectly tolerates aggressive atmospheric effects. It is easy to install, does not require large monetary costs and allows you to obtain roofing structures with excellent aesthetic properties.
Among the main advantages of ondulin, we can distinguish the following:
- excellent indicators of environmental cleanliness;
- impressive service life;
- beautiful appearance;
- richness of color scale;
- simplicity and good speed of installation;
- convenient dimensions that contribute to reducing the amount of waste and increasing the speed of implementation installation works.
The listed characteristics made ondulin very popular among private developers. The absence of harmful components in the composition of sheets allows the use of ondulin even for the arrangement of the roof of wooden houses.
In addition, ondulin allows you to repair the old roof without first removing the existing coating. Sheets comparatively weigh a little - about 3 kg per 1 m2 of cover, so there is no need to worry about a significant increase in the load on rafters, walls and the whole house.
The manufacturer provides a 15-year guarantee for ondulin. In practice, it is established that a properly equipped roofing structure without any problems serves more than 50 years, without requiring repair.
In addition to the number of advantages can be attributed to the ability of the material to maintain its original external data during almost the entire lifetime - the paint does not crack and does not exfoliate.
The main advantage for private developers is the possibility of laying ondulin with their own hands.
The technology of laying ondulin sheets is in many ways reminiscent of the installation of slate. However, the ondulin is superior to slate in terms of mass, strength and environmental friendliness.
However, with all the merits of ondulin, he has a large disadvantage - high flammability. True, modern materials in the production process are treated with special flame retardants, which significantly reduces their flammability.
Also the disadvantage of modern roofing sheets is their tendency to lose color saturation with prolonged use. This is especially true for sheets of dark shades.
How to distinguish quality ondulin?
Many unscrupulous sellers will try to mislead you by giving out absolutely different materials for quality branded ondulin. Remember these simple recommendations, and you can choose a really high-quality roofing material.
To distinguish the original from a fake it is possible on the following grounds:
- the back of quality sheets is covered with a black mesh;
- the original sheet consists of ten waves;
- wave height - 36 mm;
- the outer side of the sheet is rough to the touch, something like gauze;
- quality sheets have a saturated matte color;
- on the extreme wave there is a seal with the marking of the plant-making fir;
- the material is accompanied by a brand certificate and a guarantee coupon valid for 15 years.
To install at the lowest cost and in the shortest possible time, and the finished coating for as long as possible fulfills all the tasks assigned to it, follow a few simple recommendations.
First of all, remember: Ondulin can not be stacked if the air temperature in the street has dropped below 0 degrees or has risen above +30 degrees. In the heat, the bitumen softens, and the sheets may become deformed. In the cold, the ondulin can simply crack under the weight of the fitter or when piercing with a nail.
Although the manufacturer and allows the possibility of laying the roof at a temperature of the order of -5 degrees, it is better to abstain from such experiments.
When stacking in the heat, make sure that the sheets are mounted without stretching. Ignoring this requirement will result in the fact that in cold weather the coating simply deforms and even is covered with cracks in the locations of the fastening elements.
For cutting ondulin, it is best to use a wood hanger, pre-lubricated with oil - with such processing, the hacksaw will not get stuck. Also ondulin can be cut with a circular saw. Bulgarian can not be used - the sheet covering will melt, and it will very quickly fail.
To fix the cover sheets to the lath, only nails specially designed for fixing this material can be used. Better buy them right away with the onduline. On the fixing of one whole sheet should go 20 nails: 10 pieces from below, 5 on top and 5 on the middle part.
When choosing the design of the crate for the ondulin, it is necessary to take into account such an indicator as the slope of the ramp. If the roof slope is not tilted by more than 10 degrees, make a solid and reliable crate of pile-faced boards or plywood sheets. If the slope is 10-15 degrees, you can use a crate with the placement of elements at a distance of about 45 cm. And if the slope of the ramp exceeds 15 degrees, fasten the elements of the battens in 60 cm increments.
Regardless of the type of skeleton frame chosen, the lath on the ribs, valleys and skates must be strictly continuous. These places need particularly careful insulation, so the thinned lath will not work.
Step-by-step instruction on installation of ondulin
Ondulin - installation by technology
Fill the cells of the roof with a heater, and on top of it fasten the waterproofing film to the rafters.
Fill over the laths of the slats of the control unit to create a technological ventilation gap.
The second step. Start laying the ondulin. First fix the row, beginning with the bottom of the roof slope. Choose the opposite side to the prevailing direction of the wind movement - so the air flows will not blow out roof covering.
Fix the sheets so that their lower edge extends slightly beyond the cornice board. Select the length of the protrusion individually. It should be enough for a normal drainage of moisture approximately in the middle of the cornice groove. At the same time, the projection should not be more than 7 cm.
Ondulin stack with an overlap in one wave. The end overlap depends on the slope of the roofing skate and can be from 17 to 30 cm.
Lay the first row of ondulin completely.
The third step. The second and each next even row stack, starting with a half sheet. So you "will dissolve" the joints of roofing elements in adjacent rows.
Lay out the ranks of such a scheme, until you reach the roof ridge.
The fourth step. Before assembling the finishing rows, fix the additional crate for the ridge profile. The hobby is best done with standard profiles from the same manufacturer, whose ondulin you use. Profiles should overlap each other by 12.5 cm. Nail the roof ridge to each wave of the sheet.
Fifth step. If between a wall and roofing structure there are joints, decorate them with the help of standard profiles of the same manufacturer. Also the profiles form the joints of different planes of the roof covering (valley).
The sixth step. Provide a reliable waterproofing of the joints of the roof and the pediment board. This can be done in two ways. The first is to bend the edge of the onduline sheet and nail it to the pediment board. The second is to impose on the roof edge an ordinary rectangular profile, also known as a gable element.
Care of the finished roof
Roof construction of ondulin does not need special care. You will only need to remove excessive contaminants in time to prolong the life of the coating.
After some time, the ondulin may lose its original color. To restore an attractive appearance it will be enough to cover the sheets with special paint.
Thus, the roof of ondulin without any problems fits with their own hands. Follow these technological recommendations, and the finished coating will serve you faithfully for dozens of years.
Video - Roof from ondulin with your own hands
The most common variant of roofing with your own hands, without involving specialists - is covered with onduline. Consequently, you can seriously save on the labor force.
Ondulin, in essence, is a kind of slate, only from a more flexible material. The basis is taken by the organic mass, which is impregnated with bitumen.
Ondulin has high strength, as well as water resistance. This is possible due to the fact that it is produced in chambers high pressure, while heating bitumen to a temperature of 120-140 degrees.
As part of modern ondulin, you can find:
- cellulose-fibrous bases;
- mineral components acting as a filler;
- various resins that increase the heat resistance of the material;
- various colorants, most of them pigments of mineral rock.
Thanks to all these elements, the basis of organic fibers, ondulin has a presentable and aesthetic appearance, it can remain in its original form for a long time.
Advantages of ondulin
There has appeared ondulin in the EU countries and still enjoys popularity there. Now he is very in demand with us. It has such advantages:
- Roof roofing with onduline makes it possible to get a waterproof coating. Features of production allow this material to have zero water absorption. Even in the rainy season, it does not absorb water.
- Temperature influence, its differences are also not terrible for this coating. Ondulin easily stands before the hot sun and in severe frost. It does not even crack, which happens with many other materials.
- Another feature is the resistance of the material to bacteria, fungi. This material does not damage insects. Even a variety of alkalis and acids are not harmful.
- It has this material and good oil resistance, which is useful for industrial buildings.
- This material is UV-resistant. He does not change his original color even after several years.
- A small mass of material will be useful when work is to be done alone.
- Ondulin in the modern market is offered in a variety of colors, so you can easily think over your own original roof pattern.
Preparatory work
On the part of the installation work with the ondulin resembles the installation of a slate roof. There is also a small difference, which must be taken into account.
The first stage, just before work, will be a thorough miscalculation of the required amount of material to cover the roof. The simplest option for calculation is the use of special online calculators directly on the sites of construction companies. If you carry out repairs, you can simply count the number of sheets used.
Further, covering the roof with ondulin requires certain weather conditions. In particular, the temperature should be above 0 degrees, down to 30. This is easily explained by the fact that even with a slight frost, the ondulin becomes fragile. It's not scary when onduline is laid on the roof, it's quite another thing, if manipulation is still to be performed. Then you risk to do marriage, and you have to buy the material. Again, if you nod on the frost with nails - there is a possibility of cracks.
Direct mounting
Mount ondwin to the roof follows with the help of special nails, differing with a hat of a special shape. Their consumption is easy to calculate: one ninety-two-ounce sheet of ondulin will need 20 nails. Half will go to the top of the sheet, the second half to the bottom.
Stroke ondulin should be so that the vertical joints do not match. Nails are driven just at the junctions. Particular attention should be paid to the place where 3 sheets will be fastened at once. In the figure, this place is circled. It is here that the sheets No. 1, 4 and 5 are joined. Again, the sheets should be overlapped.
If the roof slopes are flat, up to 10 degrees, under the ondulin you should make a continuous crate, the material for which may be a moisture-resistant plywood. If the roof slope is very steep, it is allowed to use the laths from the timber. If the angle of the ramp is greater, the step of the battens is less frequent.
Under the onduline does not necessarily lie waterproofing. But still, it is better to do it. Waterproofing is usually laid on top of the crate. You can use both hydro- and vapor barrier. This will be especially true if the roof is equipped with an attic or a heated attic.
At the end of the works with the installation of waterproofing, it is necessary to proceed directly to the laying of ondulin sheets and their fastening.
Before these works, it should be noted that ondulin has another interesting property: it can stretch, stretch due to its cellulose base. Nevertheless, it can not be laid down in any way, otherwise the deformation will occur under the effect of temperature, and the roof will leak.
The laying itself should be done in an uncontrolled manner: the joints of the horizontal row must be opposite the whole parts of the row of the neighboring row. This is already mentioned above, as well as about the overlap. Depending on the angle of the ramp, overlap occurs with different lengths. For example, if the slope is less than 10 degrees, then the vertical overlap of the sheet on the sheet should be made at least 30 cm. And on the sides - in 2 waves. If the angle is larger, the steep steepness is enough to be 20 cm vertically and 1 wave horizontally.
Fastening sheets occurs as follows: first the bottom part is fastened, if it is the first horizontal row, then to the crate. Starting with the second row, you need to attach to the previous wave, then fasten the top and center parts alternately.
Already mentioned was the use of special nails. In case the crate is used from a galvanized profile - it is necessary to purchase self-drilling screws and a special drill.
Finishing work consists in the installation of curtain rods and skates.
If previously there was a different coating on the roof, for example, metal or flat slate, roofing paper, then it does not need to be removed, it is enough to hold small preparatory work with the purchased sheets of ondulin.
In the installation of ondulin, any nails will not work. We need special ones. Their peculiarity is that in the construction the base resembles a screw, which provides a better anchoring. The upper part of the nail has a special rubber gasket, which, when in close contact with the ondulin sheet, will not allow the liquid to flow under the roof. This is an additional waterproofing in the attachment points. The color of the gaskets can be matched to the color of the ondulin so that they do not catch the eye.
Separately, it should be mentioned that if the sheets of ondulin somewhere touch the wall, you need to pay special attention to the waterproofing in these places, do everything carefully. An example of such walls may be the presence chimney on the roof of a private house. In the case of pipes, you can find special aprons of rubber, which will be an excellent protection against moisture penetration.

If you have any questions about the process or there are nuances in which you would like to understand more - you will certainly be helped to watch videos on this topic.
One of the most popular ways of arranging roofing in private house-building is laying sheets roofing ondulin. Taking into account the specifics of this modern French roofing material, the technology of its laying has a certain number of features, the account of which allows us to get a high-quality and durable roof.
Variants and ways of installation
In the current market building materials roofing refers to the most perfect roofing systems, which are widely used throughout the world. Today, there are several options and ways to install this inexpensive, but high-quality roofing material.
To the old roof
The weighty advantage of ondulin is that it is not necessary to dismantle the old roof covering. It is enough simply to mount a layer of insulation, on which the roofing sheets are laid in accordance with the same technology as during the installation of a new roofing.
Stages of laying on old roof:
- pulling the rope along the lower segment of the bars and aligning the rest of the vertical bars along the distance of each fifth wave of the roofing material or after 60 centimeters;
- fixing the vapor barrier across the ramps with the help of mounting brackets in 15 centimeters increments with the subsequent gluing of joints with mounting tape;
- installation of the horizontal bar leveled to the ends of the vertical crate and fixing at the points of intersection with vertical bars samorezami 70 millimeters;
- place the layering of two sheets of the old coating to provide a cut at the level of the horizontal crate;
- laying of thermal insulation and breathing membrane;
- laying of the ondulin from the roof section opposite to the prevailing wind.
On roofing material
It is permissible to mantle the onduline sheets on the surface of the old roofing material, and all breakthroughs in the old coating should be eliminated. For high-quality installation, it is necessary to install a new counterweight in the length of the rafters and the crate crosswise rafter systems. Such work will allow the condensate or moisture to get stuck on the roofing material. Used a bar with a cross-section of 5x5 centimeters.
The grating is placed with an interval in the step of the rafters, and the crate is installed in steps of 60 centimeters. Further, all works on laying the ondulin sheets are performed according to the attached instructions.
New roof
When creating a new roof ondulin, a preliminary laying of the quality crate should be carried out at intervals according to the angle of the slope of the skates. After carrying out the lath, carefully mark out the ondulin sheets. To cut the marked roofing material, a hacksaw is most often used for wood, which is preliminarily processed for quality sliding with oil.
During installation, the following basic requirements must be observed:
- the starting row of sheets should be fixed from the back side of the blowing wind;
- the next row of sheets is attached from the previous half;
- the sheets should be attached to each wave.
Rules and technology of laying yourself
- For a continuous crate, used with a slight slope, waterproof leaf lumber or thin sheet pile boards are used. The maximum gap between such materials should not exceed five centimeters.
- For skates with average gradients of slope, a thinned dredging with a distance between the elements of 45 centimeters is required.
- For a roof with a significant pitched slope, it is necessary to mount a thinned type of a billet in steps of 60 centimeters.
The scheme and the instruction of installation of the ondulin on a roof
On correct execution of installation works, the ondulum manufacturer is applied to each manufactured product. The main stages of self-installation of roofing from sheet ondulin are as follows:
- to facilitate installation work, startup sheets of ondulin should be attached to the back leeward side of the roof edge. The second row starts with half a sheet of the first row, which forms three leaves on the corner joint;
- fasteners are driven into each wave on the end segment and the overlap of the sheet, and also on the two sides of the lateral overlap. Fastening to the intermediate bridle bars is made through a wave. Twenty roofing nails are used on one sheet;
- the assembly of the elements of the ridge begins with the back leeward side of the roof edge using an overlap of 12.5 centimeters. The location of the fastening of the ridge elements is the wave of the roofing sheet, which is joined to the ridge, and additional crate bars;
- it is necessary to mount flats, gable elements, as well as correctly form the lateral roof joints at the junction with vertical surfaces by means of a covering apron;
- the installation of a ventilation system involves the use of a roof fan, a ventilation pipe and a special comb;
- to make an exit to the roof surface and to organize the lighting of the attic space, it is required to mount a roofing window that is attached to each wave of the sheet at the junction point. By means of the top sheet, an overlap is made on the base of the roofing window;
- to perform high-quality waterproofing of roof joints with vertical surfaces, it is recommended to use an Onduflesh insulation tape.

Cost of roofing works
Despite the fact that the roof covering of sheet ondulin is easy to install independently, many homeowners prefer to use the services of professional masters who not only quickly and efficiently perform this type of roofing work, but also provide a guarantee for all the work done.
The average price of roofing works "KEY KEY" without taking into account the cost of ondulin depends on the volume and tapa of the work:
- without dismantling the old roof, including cleaning the roof, installing a counterweight and stepping dolly, as well as laying roofing onduline, skate, wind and curtain rod and chimney - 400 rubles per square meter;
- instead of the old roof with the reinforcement and repair of the truss system, including the dismantling of the roofing carpet of the old covering, the strengthening and repair of the truss system, the installation of ondulin with waterproofing, and all accessories - 800 rubles per square meter;
- complete roofing cake from the Mauerrat, including insulation, wind insulation, waterproofing, vapor barrier and internal filing with the installation of ondulin - 1200 per square meter.
Summing up
- the basic rule of independent installation of onduline - the performance of all works in strict accordance with the attached instruction;
- it is impossible to economize on the quality of lumber for the lathing, and all lumber used in the roofing system must be treated with special antiseptic compounds;
- it is necessary to strictly observe the type and step of the lathing, depending on the slope of the roof slopes.
Which can be mounted in different ways, depending on the purpose of the roof.
Roof layers that need to be covered with a roof are called roofing pie. Each of the layers of roofing cake fulfills its functions and fits in accordance with certain rules. If the laying of at least one layer of roofing pie is violated, the principle of the functional purpose of the entire roof is completely violated.
Depending on the design of the roof, from its purpose, the sequence, way of laying and the number of layers may differ slightly. In this article, you will learn, how to put ondulin correctly and how to calculate the number of sheets of the roof.
The width and length of the standard Euroshade sheet are 95 cm and 200 cm, respectively. The area of this sheet is equal to 1.92 square meters. The useful area of the material is defined without overlaps and can be: 1.3 square meters. m, 1.5 square meters. m and 1.6 square meters. m.
For the calculation of material consumption, it is necessary to determine the indicators:
- the useful area of the coating material. Depends on the angle of inclination. The multi-pitch roof shape is calculated from the total area of each of the skates;
- the area of the roof. It is determined by adding the areas of all skates to the mathematical formulas of figures (trapezoid, square, rectangle, triangle);
- number of sheets of material. It is determined by dividing the area of the whole roof by the useful area of one material web.
CAUTION!
The roof area is calculated exclusively by the eaves of the cornice, but not along the edge of the roof roofing.
The correct calculation of longitudinal lapping is of great importance, which can significantly reduce the amount of trimming. The upper row, if possible, should be laid with sheets of full length, as its height will reduce the ridge element.
There are several more correct calculation ondulin:
- when calculating, add 10% or 15-20% respectively, to a simple roof or a complex roof with different angles and transitions;
- additional elements (ridge, raindrops, tongs, aprons around chimneys and windows, junctions) require additional cover by the onduline;
- when calculating the ondulin of a mixed color solution, it is necessary to schematically scale down the roof design and to calculate the consumption of sheets of each color separately.
Special programs for calculating the consumption of coating material greatly facilitate mathematical calculations and help to more accurately calculate the amount of Euroschlar for roofing.
Ondulin - installation instructions
When the crate in accordance with the angle of inclination is mounted, it is necessary to lay the coating step by step. Installation of the undulator in steps:
ondulin (tile) installation instruction
Now you know in detail how to put ondulin. All stages of roofing provide an unmistakable laying of the ondulin, regardless of which roofing design is provided. The sequence of actions provides a good result.
Waterproofing and vapor barrier for ondulin
Firms producing ondulin, present the material, as a coating, which does not require the installation of additional vapor-insulating materials or waterproofing. In this case, it is recommended to equip the roof with a waterproofing layer of the room (or attic), which requires insulation. We also recommend the installation of a vapor barrier membrane from the side of the room.
Additional waterproofing elements and ventilation devices:
- waterproofing roofing cornice is provided with a special box, which is fixed to the base of the sheet overhang;
- ventilation is provided by ventilation pipes, which, like the window, are fixed with self-tapping screws for each wave of the coating;
- for protection from insects, a ventilating comb is mounted in the gleam under the cornice;
- joints of onduline cloths are glued by the tape produced by the manufacturer of the coating (Onduflesh);
- the junction of windows, valleys and other joints with the roof, cornices are also glued with adhesive tape;

Conclusion
The roof can be covered with ondulum quite qualitatively, if you study the principles of work and take into account the nuances of installation. Given that the material is rather light, it will be possible to erect it for one person.
In contact with
- this is one of the most popular in recent times roofing materials, which due to its excellent performance characteristics and low price has become very widespread.
How to cover the roof with undelin today almost every specialist knows roofing works. The technology of making ondulin involves the use of cellulose, which is impregnated with bitumen and thermally cured resins under the influence of high temperature. On the front side, the roofing sheets are coated with a paint of a special composition that gives them an aesthetic appearance and provides a high degree of protection against mechanical loads and moisture.
Nowadays, the ondulin is made of multi-layered, which makes it possible to obtain a moisture-proof and environmentally friendly material with high mechanical strength. It does not have harmful effects on humans and can be reused after processing. With a finished sheet area of approximately 2 m 2, it can be argued that ondulin is the most technologically and quickest way to cover the roof.
Advantages of working with ondulin
Covering the roof with ondulin gives a lot of advantages, namely:
- the roof will have a presentable appearance and a flat surface;
- ondulin is not susceptible to corrosion, resistant to chemically active substances and ultraviolet radiation, fungi and microorganisms;
- provides excellent soundproofing and a long service life;
- low cost;
- this material is excellent for radial bends and non-standard roofs;
- guarantees easy and simple installation;
- there is a possibility of an individual choice of a color solution from a huge range of offered shades.
To cover the roof with an ondulum with your own hands, you should know the main rules of the technology of its installation:
Crawl the roof correctly
Before covering the roof with ondulin, it is advisable to familiarize yourself with these recommendations in full and take them into account in your work.
Starting laying soft roofing from ondulin, it is necessary to provide for the necessity of carrying out thermal insulation and waterproofing. In the case of a heater, they can create the necessary ventilation clearance between the roof and thermal insulation. The marking of the onduline roof is done in color pencil, which is the most acceptable option for a wavy surface. If necessary, cut off the ondulin sheet, it is best to use a hacksaw on wood, which is previously oiled, or Bulgarian.
The ondulin sheet weighs approximately 6 kg, which allows it to independently lift and install it. Fastening of sheets by nails necessarily carry out in following places:
- at the end of the sheet on each wave;
- on each overlap (end and side);
- the number of nails used for each sheet is approximately 20 pieces.
When fixing ondulin to the metal surface, self-tapping screws are used, which create a more reliable grip of the roofing material and the crate. After the end of fixing the ondulin sheets, the joints are waterproofed, which is carried out with a special insulating tape.
Roof roof can be executed directly on top of old roofing materials that have lost their properties. Also allowed as a partial replacement of roof elements, and a complete renovation with the installation of ondulin.
Installation of the first row of the roof starts from the very bottom of the roof, with the opposite leeward side of the roof. The purpose of this is to prevent wind blowing under the edges of the sheets to avoid mechanical deformation of the material. The underside of the roof should protrude from the cornice board (cornice overhang), thereby preventing water from falling from the roof onto the cornice.
To install ondulin sheets on the old roof, you need to verify the reliability and integrity of the main constructive elements bearing structure. They have to withstand not only the old roof, but also the load of new roofing materials. If necessary, reinforce the structure or remove the old roofing. The possibility of erection over old coatings made ondulin one of the most unique and sought-after roofing materials, which open unlimited possibilities for construction organizations.
After mastering the theoretical material on how to cover the roof with ondulin, you can proceed directly to the organization of these works and the procurement of materials.
Signs of the original ondulin
Today in the construction market there are a lot of enterprises that produce soft bituminous roofing under different brands. But its quality is not always high, so it is worth knowing the main features of this branded ondulin:
