Metal tile is a lightweight, compact sheet material. Modern production technologies and plastisol coating ensure its excellent performance and aesthetic appearance..
Self-assembly of metal roofing is not a very simple process that requires patience, time and effort..
First, a hydro-vapor barrier or membrane film is laid on the rafters, which prevents water condensate from penetrating into the heat-insulating layer of the roof. Film sheets are laid with an overlap from the bottom up. They are fastened with slats with a slight tension – the film should lie freely, not sagging, but not be tightly stretched.
The crate is made of boards or timber with a width of about 100 mm. The board facing the cornice must necessarily be 10 mm thicker than the others, and the distance between the boards is equal to the pitch of the metal tile profile.
The eaves plank is attached to the last board of the crate. The overlap of the planks is 100 mm in length. Fastening sheets on a gable roof starts from the end. The installation of the roof of a hipped roof starts from the highest point in the direction in different directions. Each sheet is set under the extreme wave of the previous one. The edge sheet of the metal tile is set at 40 mm. below the eaves.
The very first sheet is attached to the crate at the ridge. Then, also with the help of self-tapping screws, the second sheet is fixed. Self-tapping screws are screwed perpendicular to the surface of the sheet into the deflection of the wave of the metal profile. A feature of the metal tile is the presence of special locks on opposite sides of the sheet. Thus, the result is a single monolithic coating. Its bottom edge should be a straight line..
Installation of metal roofing should be carried out using repair paint to eliminate possible damage to the coating of metal sheets – scratches, chips. If necessary, the sheets are cut with a hacksaw for metal. Sections are also covered with paint, which will prevent the development of corrosion. Work shoes should be soft, metal chips should be removed from the roof surface with a soft brush.
Finished metal roofing can be subsequently painted. Moreover, at least one layer more is applied to its descent than to the rest of the area. It is on the descent that moisture and debris linger more often, damaging the protective layer of the metal tile.
If you have doubts about your abilities or time constraints, it is better to entrust the installation of the roof to professionals..
