How to roof with ondulin
There are many classes of coatings for the arrangement of the roof, widely used not only in private housing, but also in large-scale industrial construction. One of the most popular materials used to close the roofs of buildings is Ondulin.
It has the following properties:
- decorative appeal;
- increased wear resistance;
- profitability and ease of installation.
Training
Onduin – это уникальный кровельный материал, выполненный в виде легких и износоустойчивых листов волнообразной формы, способных надежно защитить крышу от осадков, ветра и других климатических воздействий. Onduinовые кровли принято относить к надёжным и добротным конструкциям, которые могут использоваться на строениях любого класса и способны выдерживать самые суровые климатические испытания.
Another indisputable advantage of this material is the relatively short time of its installation with the comparative simplicity of all major assembly operations. The economic effect of its use is achieved due to the fact that ondulin is allowed to be laid on the old roof. The process of laying it does not need any complex tool and the availability of training from the performer. The owner of the building will be quite able to cope with such a serious task as covering the roof with an ondulin.
Note! Before laying on the old coating, you must first check the strength of the truss system existing on the building and determine whether it can withstand the increased load.
Obesity
For the newly constructed roof, you will need to build a reliable crate of wood bars on it, on which ondulin sheets will be subsequently laid and fastened. In addition to its main (carrier) function, the batten is usually used for mounting on it such mandatory elements for the roof as heat and waterproofing coatings.
Obesity делается с небольшим шагом, что объясняется мягкостью этого материала — он при крупноячеистой основе будет элементарно провисать под весом скопившегося снега. Obesity производится с учётом угла наклона кровли и преимущественного для данной местности направления ветра. Начальный участок выбирается при этом со стороны, обдуваемой реже всего.
Note! When assembling the construction of bars, sheathing, fastened to the rafters, are arranged with a pre-calculated step. Subsequently, this distance is strictly maintained over the entire coverage area.
The main technical characteristics of the classic stingray closed by ondulin look roughly as follows:
- roof slope - from 20 degrees;
- the step of stuffing crates bars - ranging from 60 to 80 cm;
- at a step greater than 80 cm, additional rails should be filled between the bars.
Assembly work
For the construction of high-quality roof, which could serve you for many years, it is recommended to get acquainted with a number of nuances concerning the technology of installation of ondulinovogo material:
- If you need to move in the course of work on an already laid area, try to step on the crest of a sheet wave, since the gap between them may not withstand a large load and crack.
- Roofing is allowed to be performed at ambient temperatures from -5 to +30 degrees Celsius. At temperatures different from those specified, the manufacturer does not guarantee the preservation of the physical and technical characteristics stated in the passport.
- To fix a single sheet of coating, you will need a minimum of 20 fastening nails that come with the purchased material. This number is selected on the basis of the requirements of reliability of attachment, taking into account its resistance to strong gusts of wind.
- The crate for ondulin is customarily made from wooden bars with a cross section of 60 × 40 mm.
The choice of the step of stuffing the longitudinal bars depends on the working angle of inclination of the roof to be closed:
- at an angle of less than 10 degrees, continuous plywood crate is used;
- when the angle is in the range from 10 to 15 degrees, the distance between the bars is selected about 450 mm;
- in the event that the angle of the slope is noticeably greater than 15 degrees, the limiting step of stuffing the bars should be of the order of 600-800 mm.
Note! Before mounting the ondulin, it is necessary to carefully control the linearity of the joints in all planes. It is not allowed to excessively “stretch” the sheet blank on the roof surface. Before final fastening, make sure that the sheet is evenly placed on the mounting surface. The material is cut by a hacksaw on a tree, the canvas of which is preliminarily lubricated with technical oil.
Installation of the first row is from the very edge of the roof. To close the next row, a half sheet is used (cut into two longitudinal parts). Sheets are fixed on the batten uneven bars with special nails that resemble screws in their external appearance. When attaching the first row, use fasteners in each crest of the wave; in all subsequent rows can be fastened through one ridge. Each successive row must overlap with respect to the previous one.
Ondulin blanks, mounted in a vertical plane, are also fixed on the uneven bars of the sheathing with a longitudinal overlap in one wave; at the same time, the transverse overlap can be about fifteen centimeters. At the final stage of the work, the assembly of ridge elements, which are overlapped along the sheet wave, is carried out.
Cost of
The cost of the source material (an ondulin standard sheet weighing about 6 kg) varies between 400 and 500 rubles and depends on the completeness of the product unit and its color.
The total material requirement is defined as the total number of sheets of a given area required to close the surface of the batten, whose area is calculated without much difficulty. But there is one significant subtlety that can affect the correctness of the calculation. Part of the area of the sheet will be located under the adjacent blanks (remember about laying overlap). That is why, when estimating quantities, it is necessary to introduce a small correction to the so-called “overlap” in their calculation.
These calculations are the inconvenience that you have to put up with because of the possibility to make installation yourself and do without hired workers.

Advantages and disadvantages
Onduin имеет свои сильные и слабые стороны. К его бесспорным достоинствам можно отнести:
- low price and environmental friendliness;
- ease and simplicity of installation;
- long service life;
- the possibility of laying on the previous coating;
- resistance to aggressive media (acid, alkali and fungus).
The disadvantages of this material are:
- high flammability;
- rough surface, keeping snow on the roof plane;
- poor selection of colors;
- burnout in direct sunlight.
Now you can evaluate the feasibility of using it for arranging the roof of your house
