First, use 28 for the roof × 35mm thick cement mortar leveling.

Pave the first layer of asphalt tile, with the adhesive facing upward, and directly pave it on the roof along the roof slope bottom. At one end of the cornice at the root of the wall, the initial layer of asphalt tile extends 5 to 10 mm. Fix the ground with a nail 50.8 mm from the bottom of both ends and 25.4 mm from the side, and then place it evenly in the horizontal direction between the two nails. Place 2 nails and catch the horizontal line.

Lay the first layer of asphalt tile, wipe off 167mm of the first layer of asphalt tile, and then lay the whole asphalt tile. Align the first asphalt brick along the end of the wall and the edge of the initial layer of asphalt brick along the cornice. Fix with nails at 60.8mm from both ends to the bottom and 35.4mm from the side, then set two more nails in the horizontal direction of the two nails and snap the horizontal line.

Lay the second layer of asphalt tile. The side of the first layer of asphalt facing brick of the second layer is staggered by half a leaf from the side of the first layer of asphalt facing brick. The bottom of the second layer of asphalt tile is flush with the top of the decorative joint of the first layer of asphalt tile. Use the horizontal line snapped on the first layer of asphalt tile to make the bottom of the second layer of asphalt tile parallel to the cornice, and fix the second layer of asphalt tile with nails.

Lay the third layer of asphalt tile, cut the whole blade of the first layer of asphalt tile of the third layer of asphalt tile, stagger it with the first layer of asphalt tile of the second layer of asphalt tile, make the bottom edge of the third layer of asphalt tile flush with the top of the decorative joint of the second layer of asphalt tile, and then lay and fix it down successively with the whole third layer of asphalt tile.

Pave asphalt tiles on the gutter. The asphalt tiles of intersecting roofs shall be laid to the gutter at the same time, or each side shall be constructed separately, and shall be laid to 75mm from the center line of the gutter. Then pave the gutter asphalt tile upward along one of the roof eaves and extend over the gutter, so that the last gutter asphalt tile of the layer extends to the adjacent roof for at least 300 mm, and then pave the gutter asphalt tile along the adjacent roof eaves and extend to the gutter and the previously laid drainage ditch asphalt tile, which shall be woven together. The trench asphalt tile shall be firmly fixed in the trench, and the trench asphalt tile shall be fixed by fixing and sealing the trench.

When laying ridge asphalt tiles, first slightly adjust the last several asphalt tiles that have been laid upward on the two top surfaces of the inclined ridge and the ridge, so that the ridge asphalt tiles completely cover the top asphalt tiles, and the overlapping width of the ridges on both sides of the ridge is the same. After the nail is fixed, coat the exposed asphalt tile with asphalt glue.
