Planning to reinforce your commercial roofing system to make it more walkable? Nowadays, roofers are recommending that you have a polyvinyl chloride (PVC) membrane installed in your system. This roofing material is made with polyester added in between the PVC’s two layers to make it more durable. It’s also very affordable, which is another contributing factor to its growing popularity. However, its reinforcement capabilities and affordability isn’t the only reason it’s good for your roof; PVC membranes actually have many benefits.
