Iron roofs are more commonly used, and residents build their own balconies and terraces with colored steel tile roofs. After several years of exposure to wind and sun, the blue paint on the surface of the color steel tiles will gradually fall off. The metal of the color steel tiles will be exposed and will soon rust. In a short period of time, the surface of the color steel tiles will be rusted. holes, and then the color steel tiles need to be replaced. The color steel tile roof is waterproofed by using SBS modified asphalt waterproofing membrane. In this way, the SBS modified asphalt waterproofing membrane covers the entire surface of the color steel tile underneath. The color steel tile is not directly exposed to the wind and sun. It can extend the service life of color steel tiles.
The joints of the color steel tiles are generally sealed with glass glue. However, after a few years, the color steel tiles will be partially deformed due to various factors, and the glass glue sealing areas will crack. The iron sheet of the tiles will also become warped in some places. If the glass glue is applied again, the effect will not be as good as the new color steel tiles. Water leakage often still occurs after the glue is applied.
After the surface SBS modified asphalt waterproofing membrane ages and cracks, the brand-new color steel tiles will be exposed, and the SBS modified asphalt waterproofing membrane is an elastic hot-melt waterproofing membrane. Paving on the surface of color steel tiles can ensure that in high temperature and frost environments, the color steel tiles can expand and contract freely without cracking of the waterproof membrane, which makes it difficult to provide long-lasting waterproofing effect.
