The leakage of vertical locking roof of aluminum magnesium manganese plate occursfrequently. Therefore, the roof model is established by BIM and Fuzor software to find out the prone partsof roof leakage under the conditions of storm, rainstorm and snowstorm, and to optimize the roof drainageand key node construction scheme. The vertical locking curved roof waterproof roll⁃roofing materialsgroove sealing device is developed to solve the integrity problem of waterproof roll⁃roofing materialsdamaged by the construction of roof fixed base and ensure the effectiveness of waterproof roll⁃roofingmaterials. Using aluminum magnesium manganese plate seamless welding instead of flashing plate, theproblem of leakage of flashing plate at the side of vertical locking roof light is solved.
