What is the angle of a pitched roof

Any angle can be, the problem is to look at the height of your house gable and top to determine.

Slope roof slope in ten degrees to sixty degrees, more than ten degrees for the slope of the roof, thirty degrees for the best slope, the top surface of the force is reduced, easy to drain.

Sloped roofs are generally 30%, the slope of the sloped roof is generally 10% - 60%. The slope of the roof is more than 10% for the sloping roof. Is the uppermost layer of the building and outdoor separation of the peripheral components, the roof can play a role in resistance to rain, snow, sunscreen, cold, heat insulation and so on.

Extended information:

Sloped roofs, also known as pitched roofs, are roofs with drainage slopes that are generally greater than 3%. Sloped roofs are widely used in construction, mainly single-slope, double-slope, four-slope and folded waist type.

The double-slope and four-slope type used more. Double-slope roof at the end of the roof pick in the wall outside the so-called hanging mountain; mountain wall and the roof of the flat so-called hard mountain. The traditional Chinese four-slope roof is called hipped at the four corners; the main ridge is extended, and the two sides of the roof form two mountain flower faces, which is called hiatus. Tile lines converge at one point in the form of sloping roof for the save pointed roof, often arranged at this point of the roof of the treasure.

There are many types of roofing materials, the choice should be based on the form of supporting structure, roof slope, building appearance, durability, fire resistance, waterproofing, self-weight, construction requirements, cost and other comprehensive consideration. Commonly used:

Flat tile roof

This roof is made of clay burnt or cement mortar molded into a concave-convex pattern of flat tiles. The external dimensions of the tiles are generally 400 x 230 x 15 mm, and there are hooks on the back of the tiles, which can be hung on the tile hanging bar. When laying, the top, bottom, left and right must be lapped. This roofing construction is convenient, widely used in civil construction, the disadvantage is that the size of the tile is small, more seams, easy to seepage and leakage.

Corrugated tile roof

This roof is commonly used asbestos cement corrugated tile, wire mesh cement corrugated tile, colored fiberglass corrugated tile, galvanized tile Monopoly iron, aluminum alloy corrugated tile, as well as after the surface of the coloring and anticorrosive treatment of wood fiber corrugated tile, etc.. Waveform tile light weight, good appearance and waterproof performance, all types of waveform tile covering method is similar.

such as asbestos cement corrugated tile is usually galvanized iron screws or iron hooks directly nailed or hooked on the purlin, purlin spacing is generally 900 ~ 1200 mm. Between the tile and the tile shall be up and down, left and right lap, left and right lap direction should follow the dominant wind direction. In order to prevent the unevenness of the splices of the four pieces of tile, commonly used cutting corner paving method.

Other roofs

In addition, there are glazed tiles, small green tiles, tube board tiles and prefabricated reinforced concrete roof tiles. Glazed tiles are mostly used in large-scale public **** buildings such as memorial halls as roof or wall eaves decoration; small green tiles and tube plate tiles are mostly used in residential buildings; reinforced concrete roof tiles have п-shaped boards, F-shaped boards and steel wire cement channel tiles. Their large size, can be directly laid on the roof frame or purlin, do not need to make another roof.
