How do you know when to replace a PVC roof?

PVC (Polyvinyl Chloride) is hands down the best low slope and flat roofing material on the market today. Engineered to be flexible, strong and UV reflective, PVC roofing can easily last 20 years here in the Pacific Northwest. The flexibility of PVC roofing makes it easier for roofers to install the product around roof penetrations like vents, chimneys and skylights. Valentine Roofing employs experienced PVC crews that receive ongoing training in installation and product knowledge.
