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. Some contractors will offer other products such as TPO, Torch Down, Hot Tar and EPDM for low slope and flat roofs. These other products can be dangerous to install, using open flames or super heated material. While they may seem appealing when presented with the upfront cost these products often last half as long as PVC typically requiring expensive maintenance or repairs.
