When replacing the final roof covering, including with metal tiles, it is necessary first of all to check whether there are any flaws in the roofing pie. In particular, whether the gap between the waterproofing layer and the crate to which the roofing material will be attached has disappeared. It is necessary to provide ventilation, which prevents condensation of water vapors under metal tiles, which can render unusable both the roofing material itself and the material from which the thermal insulation is made. To ensure such a gap between the crate and the waterproofing layer, it is necessary to install a counter-crate made of wooden beams that are nailed to the rafters.
The crate itself for metal tiles can be made from boards with a width of 25 millimeters, since metal tiles weigh a little, and such a section of boards in width will be quite enough.
There are three types of crates. It can be stepwise, continuous, or combined. The most common is a step crate. It is suitable for any roof with a slope of no more than twenty degrees. The distance between the axes of the adjacent boards should correspond to the wavelength of the metal tile sheets.
A solid crate is used for roofs with a slope from 14 to 20 degrees. 14 degrees is the minimum slope allowed for a metal roof. When mounting a solid crate, it is necessary to leave technical gaps between the boards, which, in the case of "walking" the boards, will not allow the crate to bulge.
Also, when installing a metal roof, a combined crate is used. In this case, the step part is mounted on the main roof area, and the solid part is installed in those places where the roofing material will come into contact with walls or pipes. The solid box is mounted near the skylights, roof hatches, near the inner and outer roof slopes. It is also installed under elements that ensure the safety of roof operation and maintenance: under snow holders, fences, stairs. Also, a solid crate is installed under the roof ridges.
When mounting a crate for metal tiles, it is necessary to take into account the step between the waves of this roofing material. The pitch of the metal tile must necessarily coincide with the distance between the axes of the crate boards. It should not be increased in any way, as this may cause deformation of the metal roof.
