Common leakage areas for steel structure color steel tile roofs and gutters

1. Gutter span with uneven foundation settlement loads can lead to cracking due to uneven tension. Cracks are exacerbated by external temperature changes, thermal expansion and contraction, and the material's extensibility, resulting in stress mismatches and leakage.
2. Leaking issues are quite severe in steel structure color steel roof systems due to installation and construction, roof elastic deformation, and roof vibration. Steel structure roof leaks are primarily concentrated in areas such as vertical and horizontal joints of metal color steel roof tiles, ridge areas, skylight panels, fan bases, chimney pipes, all roof screws, gutters, and junctions of parapet walls.

Steel Structure Color Steel Roofing Sheets and Gutter Waterproofing Features

Wide span, prone to cracking and deformation.
2. Multiple factory equipment, high waterproofing requirements.
3. Severe leakage issues due to elastic deformation of steel structure roofs and vibrations in color steel roofs are more pronounced in southern regions.

Material Selection Principles for Roofing and Eaves Waterproofing of Steel Structure Buildings

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials with strong adhesion to the roof joints, high elongation, resistance to high and low temperatures, sun radiation, water resistance, airtightness, and good aging and weather resistance.
2. The steel structure roof waterproofing system features light weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long lifespan. It can completely resolve issues such as leakage and seepage, condensation on cold bridges, and multi-curvature construction in traditional roofing systems.
