Common leak locations in steel structure color steel tile roof and gutters

1. Gutter span uneven foundation settlement load causes cracking, with the temperature's influence creating stress mismatches due to thermal expansion and contraction, as well as the ductility leading to leakage.
2. Steel structure color steel roof leaks are quite severe due to reasons such as installation construction, roof elastic deformation, and roof vibration. The main leak points of steel structure roofs are concentrated at junctions such as vertical and horizontal joints of metal color steel tiles, ridge, skylight panels, fan bases, chimney pipes, all roof screws, gutters, and the junctions of the parapet walls.

Structural steel color steel roof tiles and gutter waterproofing features

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

Principles for Waterproofing Materials Selection for Steel Structure Roofs and Eaves Gutters

The waterproofing layer must match the changing characteristics of the steel structure roof. It is essential to choose materials with strong bonding force on 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 roofing waterproofing system is characterized by its light weight, excellent waterproof and thermal insulation performance, ease of maintenance, and long service life. It can effectively address issues such as leakage, condensation on cold bridges, and multi-surface structures in traditional roofing systems.
