Covering the roof with ondulin is not so difficult. Although the process has some features on which the quality of the roof depends. First of all, we will understand why the material presented is so popular. The fact is that it is very durable, protects the roof well, is easy to install, has a small weight. And this material is produced in different colors. In addition, this roof is a very economical option.
Before
covering the roof with ondulin, carefully inspect the sheets of material. They must be of high quality, without dents, bends or cracks. It is very important during operation to take into account the step of the crate and the size of the overlap (2 waves at the side, 30 cm at the edges of the sheet).
Before laying the material, the roof should be prepared. To do this, a crate is mounted on the rafters. For its manufacture, wood or metal is taken. It is very important to maintain the correct center distance. Before covering the roof with ondulin, you need to carefully consider the marking of the wavy surface.
Since the sheets will have to be cut, for this you should use a hacksaw with small teeth. First you need to grease the canvas with oil. In addition, a circular saw is used to cut the material . For the installation of ondulin, you do not need to assemble a whole team of workers, since this roof is very light. Start laying from the side where the wind blows harder. The first row is mounted from the bottom of the ramp, the next - from half of the canvas. During operation, the level must be strictly observed.
Before covering the roof with ondulin on skates, an additional crate should be arranged. Mount it begins on the
leeward side. Nails must be hammered into every wave that fits with the ridge.
During the construction of the roof, some nuances should be taken into account:
- You can only step on the crest of the wave sheet;
- all work should be carried out only if the temperature is outside. Do not lay material if it is cold or very hot outside;
- In order to attach one sheet of material, about 20 nails should be used. Such a requirement is provided by the guarantee, therefore it must be observed without fail. The fact is that poorly nailed sheets with a strong wind can simply rip off. In this case, the canvas is not desirable to stretch.
Before covering the roof with ondulin, special nails should be purchased. Often they are sold complete with
roofing material. Lay sheets should be with a certain
slope of the roof. The thickness of the bars of which the crate is made depends on this. In addition, the overlap with which the sheets will be stacked on each other also depends on
the angle of the roof .
If you still do not understand how to properly cover the roof with ondulin, or are afraid to do it yourself, then you can use the services of experienced builders. In principle, the laying of the presented material does not have to be very expensive. Moreover, you will have a guarantee on work.
