1. Due to the problems of large roof slope and many ridges, the elevation of the main trunk, cornice, tiger window, submerged line and other parts of the house must be accurately controlled in the whole construction process; the starting and ending points of slope angle line, cornice line, corner line and catchment line must be accurately positioned; attention must be paid to the construction safety in the erection and demolition of scaffold to ensure normal construction.
2. When the roof slope is large, the safety technical disclosure must be strictly carried out to the workers during the foundation treatment and tile hanging to ensure the safety protection.
3. Strictly control the layout of color steel tile, and handle the joint of internal and external corners, end tile and roof structure to prevent leakage.
4. Safety fence and safety net or other protective measures to prevent falling must be set around the roof and reserved holes.
