Is polyurea or polyurethane better for roofing?

1, excellent waterproof performance: polyurea waterproof coating has excellent waterproof performance, which can effectively resist water penetration, form a reliable waterproof layer and prevent roof leakage. In contrast, the waterproof performance of polyurethane is slightly inferior.

2. Excellent weather resistance: polyurea has excellent aging resistance and can resist the influence of ultraviolet rays, high temperature and low temperature. As an exposed part, the roof should be able to withstand the test of various climatic conditions. Polyurea waterproof coating is not easy to age and deteriorate under long-term ultraviolet radiation, which prolongs the service life of roof. Polyurethane has poor weather resistance.
