Common leak locations in steel structure color steel roof and gutters

1. Gutter spans with uneven foundation settlement loads can cause cracking, with cracks expanding or leaking due to external temperature effects, thermal expansion and contraction, and poor elongation and extensibility.
2. Water leakage is quite severe in steel structure color steel roof systems due to installation and construction, roof elastic deformation, and roof vibration. The leakage in steel structure roofs is mainly concentrated in nodes such as the vertical and horizontal joints of the metal color steel tiles, ridge, skylight panels, fan base, chimney pipes, all screws on the roof, gutter water trays, and junctions of the parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features

Wide span, prone to cracking and deformation.
2. Multiple factory equipment, high waterproofing requirements.
3. Leaking issues are quite severe due to elastic deformation of steel structures on roofs and vibrations of color steel roofs, a phenomenon that is more pronounced in southern regions.

Principles for selecting waterproofing materials for steel structure roofs and gutters

1. 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, solar radiation, water resistance, airtightness, and excellent aging and weather resistance.
2. The steel structure roof waterproofing system features light weight, excellent waterproof and thermal insulation performance, easy maintenance, and long lifespan. It can completely resolve issues such as leakage and water seepage, condensation on cold bridges, and multi-surface construction in traditional roofing systems.
