How durable is PVC roofing? So durable that it was chosen for the National Oceanic and Atmospheric Administration (NOAA)’s Hurricane Center located in Miami. This is an organization that knows a thing or two about the abuse extreme weather can exert on roofs. When it came time to cover its own building, the powers that be at NOAA chose PVC.
What makes PVC so durable? The Chemical Fabrics and Film Association - Vinyl Roofing Division, the trade association for the material, says it comes down to four major factors: heat-welded seams, combustion resistance, watertightness, and wind uplift rating.
