Roofing waterproof material? What kind of waterproof material is good for the roof?

Roofing waterproof materials include: polyurethane coating, composite coating, modified asphalt material and sbs modified asphalt waterproofing membrane. Waterproof material is a building envelope to prevent rain, snow and groundwater from penetrating; Prevent the erosion of moisture, steam and other harmful gases and liquids in the air; Partition wall structure should prevent water supply and drainage leakage. These anti-seepage, anti-leakage and anti-corrosion materials are collectively referred to as.

1. Polyurethane coating: Its physical properties are relatively stable, which can bring better bonding effect. In addition, this material has another feature that it can prevent ultraviolet rays. Even in hot summer, direct sunlight can better block the ultraviolet rays outside.

2, composite paint: the price is slightly higher. But the construction is relatively simple, and workers can finish it by brushing or spraying.

3. Modified asphalt material: it is an upgraded version of traditional asphalt, which has the characteristics of high temperature resistance and certain elasticity and plays a great role in roofing waterproof materials. However, it is easy to have some small cracks after being used for a long time, so its service life is relatively not particularly long, but its price is slightly lower.

4.sbs modified asphalt waterproofing membrane: it has good temperature resistance, and it is not easy to crack even if the temperature reaches MINUS 25 degrees Celsius. The performance is very outstanding, such as the temperature reaches 90 degrees, which does not affect the performance. It is a kind of waterproof coiled material with relatively stable performance.
