How to cover the roof

You can upgrade the roof with different materials: metal, corrugated, “soft” tiles, fusing with canvases, ondulin, slate. In the installation of each of them there are many common points that must be fulfilled. But there are also features.

Roof preparation for installation of roofing materials

If the roof is old, you need to make sure that the rafters are not rotted and do not need to be repaired or replaced. Before laying the roofing need to make waterproofing. For this purpose, most often used rolled materials: roofing material, rubemast, Fossil, sheet bitumen or bitumen-polymer products. The blades are rolled in the direction from the ridge to the cornice so that one of them goes onto the other not less than 15 cm. It is desirable to glue the edges of the joints with hot bitumen or suitable mastics. But private developers often ignore this recommendation.

Stages of installation of roofing materials

First of all, you need to make a crate to which the protective coating will be attached. It should be made of wooden bars, the pitch and dimensions of which vary depending on what kind of roofing material will be laid. For example, for installation of metal tiles, 4/4 or 5/5 cm bars will be needed, horizontal strips should be laid in 80-90 cm increments, vertical - 40-50 cm.
A vapor barrier is laid on top of the sheathing. For some types of roofing materials (slate, ondulin, "soft roof"), this step is not mandatory. But it is advisable not to ignore the share of preservation of the wooden elements of the roof. Vapor barrier protects the roof from moisture penetration into the "cake" and significantly increase its service life.
Installation of a protective coating begin with solid canvases. Finishing elements - eaves and end strips, endovy and horse fasten in the last turn. The first row of metal or corrugated board should be laid from the eaves, and the first canvas - from one of the ends of the roof. First, the sheet is aligned on the end, give a small allowance for the eaves and in 2-3 places fixed with screws. The second canvas is overlapped on 1 wave and is also attached with several screws. Now you need to make sure that the sheets lie flat and replace the temporary fasteners with permanent ones.
The subsequent rows of sheets are laid over the canvases of the first row, blocking them by 15-20 cm.Further, establish face and eaves levels, then - the fad. If there are snowy winters in the region where the snow covers are mounted over the roofing material.
