When working on the roof, there is often a problem of choosing a good, high-quality and durable roofing material. Experts recommend to pay attention to the environmentally safe, durable, moisture-resistant and inexpensive ondulin. How to cover the roof of their own, learn from the article.
We learn about ondulin
Ondulin is a type of roofing material that has several key advantages that significantly distinguish it from others. Externally, it is similar to Euro-slate, but does not contain asbestos that is dangerous to humans, but consists of harmless components: cellulose sheets of durable cardboard, impregnated with viscous bitumen composition, with the addition of resin hardeners and mineral elements.
To achieve high aesthetic properties of the material, various dyes are added to the binder, which allows to obtain a product with a huge color gamut.
Did you know? Ondulin - the covering material operated at different air temperatures: from - 60 to +110 degrees. But at the same time, in the heat it becomes plastic, and under the influence of frosts it becomes brittle.
Ondulin is characterized by several advantages:
- high durability of a covering and long term of operation;
- excellent resistance to moisture. Even a large amount of precipitation does not reduce its protective functions;
- excellent heat and sound insulation properties;
- resistance to mechanical damage, large surface loads;
- the ability to apply the material in any climatic conditions, including, in strong wind, snow, frost, temperature extremes;
- resistance to biological lesions: fungal diseases, mold, microorganisms;
- resistance to chemicals: gases, acids, alkalis, etc .;
- simplicity and ease of installation, which you can handle yourself.
In addition, ondulin - environmentally friendly and harmless to humans and the environment, it does not emit toxins or harmful chemicals.

Calculation of the required material
Before starting work on the shelter of the roof, you need to make calculations of the required amount of building materials.
To do this, calculate the area of the finishing base:
- if the roof is built in the form of regular geometric shapes, then for calculations it is enough to use the area formula;
- if the slopes of the roof have a complex structure, it is necessary to split the base into a number of regular shapes and, using the same formula, calculate and summarize the results.
Important! When making calculations, one should also take into account the slope of slopes relative to the ground. For example, if the roof is rectangular, and the angle of inclination is 35 degrees, then to find the final result, you need to multiply the length of the slope by its height and by the cosine of 35 degrees.
Based on the size of a single sheet of ondulin, which is approximately 1.9 square meters, you can calculate the required amount of building materials for finishing the entire roof.
Also, do not forget to take into account the amount of overlaps:
- the maximum amount of overlap will be in the implementation of the coating of a flat surface with a slope of up to 10 degrees. In such cases, the sides overlap is performed in two waves (19 cm) wide, and 30 cm in length. Thus, the useful area of the material is reduced to 1.3 square meters;
- when arranging the roof with a slope of 10-15 degrees, the amount of overlap on the sides will be equal to one leaf wave (9.5 cm), and vertically - 20 cm. The size of ondulin in this case is 1.5 square meters;
- when the roof is covered with an angle of more than 25 degrees, the overlap on the sides equals, as in the previous version, 1 wave, vertical - 17 cm. With this installation, the material area reaches 1.6 sq.m.
We recommend reading how to make the fence itself from a chain-link mesh, from gabions, a braided wooden fence, and also how to build a formwork for the foundation of the fence.
Having found out the roof area, you can easily calculate the number of sheets required for its full installation. 
Cooking tools and materials
One of the key advantages of using ondulin as a cover material is its lightness and ease of installation. To carry out the fastening of sheets, you will not need expensive equipment or special tools.
It will be useful for you to learn how to build a toilet, a cellar and a veranda, as well as how to make a brazier out of stone, a gazebo made of polycarbonate and a path made from wood cuts.
To form an ondulin roof, you must first prepare:
- directly the material itself required to cover the entire roof, with a small margin of 5-10%;
- a wooden bar with a slice of 40x40 mm, which will be needed to create the crates;
- parts for fasteners: nails with a rubberized carbon steel head, designed for ondulin;
- ridge-corner, which is located near the joint near the roof slopes;
- waterproofing film or membrane;
- ventilation duct and eaves filler.
Did you know? Experts recommend purchasing material with a margin. The size should be within 5% for simple designs and 10% for more complex configurations.Among the tools you need to have:
- sharp hacksaw to cut sheets;
- a simple pencil, ruler and tape measure for making measurements;
- small hammer;
- screwdriver for fasteners.
In order to easily reach every corner of the roof, it is also necessary to prepare the scaffolding or the ladder in advance.
Rules of transportation and storage
Ondulin sheets, required for roof finishing, can be easily transported by own car or use transportation services by hiring a small pickup or Gazelle. During transportation, care must be taken to ensure that the material is securely fixed, since sheets are not allowed to be moved when driving. 
The body of the car should be smooth and without damage, it is recommended to cover its bottom with plywood or thick cardboard. Since the weight of the building material is small, the loading and unloading operations can be performed independently.
As for the storage of the material, a dry, clean, not wet room with a flat floor is suitable for this. The storage area should be located away from heat sources, direct sunlight should not be allowed.
Ondulin is laid on the constructed flooring of boards or plywood. To protect the material from dust and dirt, it is covered with PVC film or tarpaulin.
You can also make a pergola with your own hands, a waterfall, a flower garden of wheel tires or stones, a fence, a fountain, gabions, rock arias, a ladybug, a sun wax pot and a garden swing.
Roof cleaning
Before starting roofing work, it is necessary to check the old roof covering for suitability and ability to withstand high surface loads. If the coating is thinned, then it is better to remove it, if not, then the installation can be done on top of it. 
The substrate must be carefully prepared and cleaned. It should be using conventional cleaning materials, for example, a broom with a long handle, to remove debris, remnants of foliage, branches. It is also necessary to eliminate and level the defects of the coating, process it with anti-corrosion and anti-fungal compounds.
Installation of wooden crates
In order to securely fix the ondulin, to provide future coating with resistance to deformation, high surface loads, to protect from the negative effects of moisture and direct sunlight, the sheets are laid on a special crate.
You can make a crate with your own hands from a timber with a section of 5x5 cm. The construction technology includes several stages:
- installation of longitudinal crate design;
- fastening of a bar to an old bar by means of self-tapping screws. To do this, fix the extreme elements, across them stretch the fishing line and in the direction of it attach to the other bars;
- installation of horizontal crates. Boards are fixed across the installed bars, and their intersections are fastened with self-tapping screws.
To simplify the installation, you can use the bars with existing marks. For the formation of crates in the presence of a cavity in the roof create a longitudinal structure. Moisture resistant plywood is an excellent material.
Important! The crate should be made very high quality and reliable, since if there are gaps in it, the ondulin can sag and subsequently pass moisture.
Also, when forming the crates, you should consider the angle of its slope:
- at an angle of inclination of up to 10 degrees, the design is made of a solid piece of plywood or other similar material, while the overlap in width will be equal to two waves, and in length - 30 cm;
- at an inclination of 10-15 degrees, the lathing of the bars is formed, with a step of 45 cm, while the overlap on the sides is 1 wave, on the final sheet - 20 cm;
- at an angle of more than 15 degrees, the bar construction with a step of 60 cm is built. The overlap in width is equal to one wave, in length - 17 cm.
Sheet mounting technology
Despite the ease of laying ondulin, should carefully observe the phasing and features of the process of covering the roof. The technology of mounting the material is carried out according to this algorithm:
- Installation of sheets starts from the side of the roof where it is as windless as possible. Installation of the material is carried out from the bottom. To do this, they stretch the line, which is nailed to the nails, so that the lower part of the roof has an indentation of 5-8 cm from the wall.
- When fixing the first sheet of nails driven into the second wave, located in a row from the end of the roof. The rest of the nails are driven in chess order, through a single wave. Such a procedure for hammering in nails not only makes it possible to firmly fix sheets, but also provides an aesthetic look to the roof.
- The second sheet is overlapped by one wave. At the same time make sure that the material went strictly along the marking lines. Reaching the end of the roof, you need to saw off the excess in the last sheet, using a hacksaw or a sharp saw.
- The next row is arranged in staggered order relative to the first. That is, the first sheet of the second row is cut in half and laid overlapping the initial 10-15 cm.

After the installation of the ondulin is completed, you should proceed to fixing the design parts.
Skate mounting
At the junction of two slopes, you must install the ridge, with an overlap of at least 12 cm. It must be remembered that this element is mounted on the previously installed framework of the batten. The horse can be purchased ready in stores, and you can make it yourself.
To do this, the upper sheets through the joint to withdraw, gently pulling, and fix with nails on the top of the ramp, located on the opposite side. Experts recommend to carry out such work in a warm time, when ondulin is soft and lends itself well to stretching.
To prevent the snow from blowing under the ridge during the winter period, and the moisture would not drip onto the roof, a self-adhesive waterproofing film is laid under it. You can install the same tape in places hanging sheets. This will provide an opportunity to create ventilation in the attic, to protect it from the penetration of birds, insects, etc.

Wind board fasteners
The wind board is a wooden or metal profile of a certain configuration, the main task of which is to close the end holes in order to protect it from wind, snow, moisture, as well as to quickly cool the attic.
Did you know? For fixing a single sheet of material takes about 20 nails.Wind boards are installed from the front sides of the roof, on the wave of the sheet, and they should be 35-40 mm higher than the batten.
Installation of spillway
The final stage of laying the roofing material is the installation of the spillway. For its installation it is recommended to choose a set with universal brackets that are attached to the frontal board. The diameter of the gutter and overflow pipe will depend on the area of the slope. One pipe is not more than 10 m / pog gage.

The elements intended for fixing the drain are fixed on the frontal plate. The first mount bracket, located as far as possible from the drainpipe, the second is installed one that is located near the pipe.
Next, between the two brackets, the line is tightened, along which the intermediate brackets are placed with a step specified in the instructions. When installing the spillway system, the drip pan should be placed in the middle of the gutter.
Important! It is not allowed to install the elements of the drainage system on the ondulin sheets.
After examining the rules and features of laying ondulin, you can make sure that it is not too difficult to do the roofing work yourself. The main thing is to approach work, to prepare all the necessary building materials and tools. 
Having spent a little effort and time, you can not only quickly create a beautiful and reliable covering on the new building, but also restore the old roofs that have lost their aesthetics.
Feedback from network users
My friend, if you want to cover the roof with cardboard with soaked bitumen and painted on top, then you can not look for reviews of ondulin - this is exactly what you are looking for. He has another fat plus - it burns so fast that the rafters do not have time to light up, they burn down later, after the batten. Well, the last plus if you compare ondulin or metal tile - the paint will go around for three years and as a rule it is in 3-5 years that the happy owners of ondulin roofs change the ondulin to the metal tile. I told you the main thing about ondulin, but otherwise it’s not very bad material.Flint

cottage covered with brown Ondulin - 5 years old normal flight. The neighbor has a dacha under the red Ondulin, though only 3 years old, too, is not complaining yet. Photo, litter, I will not post, because I do not want anyone to suck the architectural design of my country house. all a pleasant choice!Bijou
