As a commonly used roofing material, PVC roofing sheets typically have a service life of 8 to 20 years, depending on product quality, environmental conditions, installation, and maintenance. The quality of raw materials and thickness are key factors; high-quality virgin PVC resin and sufficient additives are the foundation for extending service life. Thicker sheets offer better performance, but one must be wary of practices that use fillers to “increase thickness” at the expense of flexibility.
