During the construction of a one-story residential building, it is best to make a roof from asbestos-cement corrugated slate sheets. This roof is quite strong, durable, fire resistant and economical. You can lay such a roof yourself, without inviting specialists.
Installation work starts from the cornice, the correct laying of sheets is controlled using a mooring cord. Slate is placed from the bottom up in a horizontal direction. Adjacent sheets are overlapped to a full wave or to one half of it. Sheets in the second row are overlapped with sheets in the first row by 10-15 cm. The size of the overlap is calculated from the slope of the roof. The larger the slope, the smaller the overlap must be.
The sheets are attached to the base using galvanized nails about 80 mm long or with screws, under the caps of which it is necessary to place washers made of galvanized metal, rubber, or linings that are made of several roofing felt layers. Nails must be driven into the crate from above through the asbestos-cement sheet, otherwise cracks and chips may appear on the sheet. Nails can be purchased today even on the Internet, where they also offer to join the np sro of designers or builders.
For greater convenience of roofing work, before they begin, special anti-wind brackets are strengthened along the eaves. They are attached two pieces to each sheet so that they can securely hold the sheet by the waves with bent ends. After completion of the roofing work, the nail heads and the small cracks that have appeared are covered with red lead mixture.
