1. Caused by natural aging
When the color steel tile roof is exposed to wind for a long time, it is easy to fluctuate and wear at the joints and screws. In this case, it will naturally rust when exposed to rain. If things go on like this, the wear and rust will become more and more serious, leading to water leakage.

2. Caused by uneven thickness of waterproof coating
The surface of color steel tiles must be coated with waterproof coatings, that is, weather-resistant glue, sealant, etc. If these coatings are not applied unevenly during construction and the thickness is inconsistent, in subsequent use, the roof will easily vibrate and stretch. cracks, causing water leakage.
3. Caused by transportation deformation. Color steel tiles are larger in size and are more inconvenient to transport. If you are not careful, they can easily cause deformation problems. At this time, slight deformation is not noticeable. The more vibrations occur during subsequent use, the greater the deformation will be. Eventually, causing water leakage.
4. Caused by aging of weather-resistant glue
When the weather is hot, the roof temperature of the color steel roof is relatively high, which will accelerate the aging of the weather-resistant glue, and will be more likely to cause problems such as cracking due to thermal expansion and contraction.
