Professional flooring for the arrangement of the roof in our time is used very often, since this material is quite durable, lightweight and resistant to atmospheric influences. But in any case, the installation of the roof from corrugated board must be done correctly and carefully. Although it does not cause difficulties.
First of all, you need to purchase high-quality roofing material. It should not have chips, scratches or other defects or damage. It is also necessary to measure the roof in order to know how long the
roofing sheets should be
. Naturally, it is necessary to take into account the fact that the sheets should protrude slightly from below. In order to calculate the amount of corrugated board, it is necessary to divide the length of the cornice of the structure by the useful width of the sheet of roofing material, and round off the resulting value to a larger side.
Before installing the roof from corrugated board, it is necessary to equip the waterproofing and ventilation of the roof. Waterproofing is provided with a special film that prevents moisture from entering the roof structure. It is necessary to lay the film from the highest point (ridge) with an overlap. The film is attached using brackets or rivets to the rafters.
In order for the roof to have good ventilation, it is necessary to nail special slats to the waterproofing, which will provide free space between the roof and the waterproofing. Further, the ventilation element is arranged on the ridge, from where fresh air enters the roof.
The coating can not just lie in the attic, so the installation of
roofing from corrugated board provides for the arrangement of the crate, the thickness of which depends on the parameters of the coating sheet. It should be borne in mind that the cornice board should have a maximum thickness, since the very first sheets are attached to it. The selected material for the lathing must be attached to the rafters with galvanized nails, which are less susceptible to corrosion.
If the installation of roofing from corrugated board involves the use of additional supporting bars, then they must be installed together with the crate.
Further, the technology of installing roofing from corrugated board is not difficult. The first sheets of material bait from left to right or vice versa. At the same time, it is very careful to move around the crate, as well as on the baited sheets. The sheets are stacked so that the anticapillary groove of one of the sheets is covered with the next sheet. Only after stacking 2 sheets is their final fixing done.
Also, installation instructions for roofing from corrugated board provide for laying sheets along the cornice line with a small ledge.
The material is fastened with screws or self-tapping screws, on which there must be special rubber seals that prevent the penetration of moisture under the roof and damage to the corrugated board. Do not tighten the screws tightly.
Lastly, the skate is installed. In this case, a sealant must be placed between the plank and the ridge. If necessary, end elements are installed on the ridge plank.
Keep in mind that when working with corrugated board, it is necessary to adhere to an inclination angle of 14 to 20 degrees.
If the material needs to be cut, it is better to do this with scissors for cutting metal.
