During the construction of a one-story residential building, it is best to make the roof from asbestos-cement corrugated slate sheets. This roof is strong enough, durable, fire resistant and economical. You can lay such a roof on your own, without inviting specialists..
Installation work starts from the eaves, the correct laying of the sheets is controlled using a mooring cord. The slate is placed from bottom to top in a horizontal direction. Adjacent sheets are overlapped on a full wave or on one half of it. The sheets in the second row are admitted to the sheets in the first row by 10-15 cm. The size of the overlap is calculated from the slope of the roof. The greater the slope, the less overlap must be done..
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 put washers made of galvanized metal, rubber, or lining made of several roofing material 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 an NP sro for designers or builders.
For greater convenience of roofing work, before starting them, 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 the bent ends. After the completion of the roofing work, the heads of the nails and the small cracks that appear are covered with red lead mixture.
