Inclined roofs are mainly aimed at roofs with a slope angle greater than 45. Especially in recent years, some European roof designs even require steeple buildings with a slope greater than 300% and a height greater than10m. These roofs require beautiful appearance, but they also emphasize the firmness of hanging tiles. The difficulty of construction is to ensure that the hanging tiles are firm, and the hanging tiles should stand the test of spring and autumn monsoon climate and not be lifted by the wind.
The ridgeline of the sloping roof should be straight, without waves and distortion. In addition to the white cotton thread pulled at the top of the roof when tiling, a wooden keel should be added to the roof to ensure that the roof lines are straight and stable. The battens shall be installed uniformly from bottom to top in a position parallel to the cornice line. The battens for hanging tiles shall be nailed flat and firm, and the upper edge of battens shall be kept in a straight line. Finally, strictly control the fluctuation of horizontal tile with cotton thread, and ensure the straight ridge with keel.

Precautions:
1, for the transition between the roof and the vertical wall, step flooding can also be used. At the junction of two sides, firstly install metal flashing with a side length of 200mm×200mm and bent at right angles, and 100mm will lap on the initial layer of colored asphalt shingles on the roof and be fixed.
2. For sloping roofs with tiger windows, the right side of the intersection between the tiger window roof and the main roof is laid by the method of unilateral overlapping gutter; The junction of the wall around the tiger window and the main roof can be laid by the above-mentioned step flooding and metal flooding or parapet flooding methods.
3. For sewage pipes and ventilation pipes protruding from the roof, the leveling layer around the pipes should be tapered, with grooves between the pipes and the leveling layer and embedded with sealing materials. Additional layers should be added around the pipeline, and a waterproof ring made of synthetic polymer material should be wrapped and bonded on the outer wall of the pipeline. The top of the flashing ring should be fastened with metal hoop, and the pipe and flashing ring should be sealed with sealing material.
