PVC is a Poly-Chloride membrane that seals your roof like a vinyl raincoat. It’s rolled out and installed with heat-welded seam technology. It’s a very popular product for flat, sloped or low pitched residential and/or commercial roof projects that need to be sealed and water-tight. It’s perfect for soggy, northwest weather conditions and it’s extremely durable in the heat as well. PVC comes in a variety of colors including reflective white which is “Energy Star” rated and can be eligible for energy tax credits.
