Roof waterproofing is very important nowadays, mainly because climate change and frequent extreme weather have put houses under greater precipitation pressure. Inadequate waterproofing measures will lead to problems such as leakage and seepage, which will not only damage the building structure, but also affect the indoor environment and living comfort. In addition, a good waterproofing system can also extend the life of the building, reduce maintenance costs, and improve energy efficiency, thereby protecting the investment and increasing the value of the property. Therefore, roof waterproofing has become a key link in construction projects that cannot be ignored.
