PVC – The Other White Sheet
Ladies and gentlemen, boys and girls, children of all ages! I proudly present to you the latest and greatest technology to hit the roofing industry since the hammer…. PVC! That opener works best if you imagine me using my announcer voice by the way.
If I’m being honest here, the PVC roofing membrane isn’t actually all that new. It’s actually been around since the mid 1960s. So why haven’t I heard of PVC in roofing you ask? Great question!
PVC Roofing Material
PVC, utilized heavily in roofing in Europe for years, is not as well known in the United States which comes down to a lack of product education to the consumer.
I imagine you immediately think of the PVC piping you used to make your potato gun when you were a kid. You’re not far off. PVC in its natural form is rigid so plasticizers are added to make it a flexible sheet for roofing.
PVC roof material is composed of two main components: ethylene and chlorine. Petroleum or natural gas is processed to produce ethylene, while chlorine is derived from salt.
PVC roof material is composed of two layers of PVC with a polyester reinforcement scrim in between. The top ply contains additives that make the membrane UV resistant. The top layer also contains the plasticizers that make the sheet flexible. The bottom ply is black PVC and also contains plasticizers for flexibility.
Benefits of PVC Roofing Material
On the roofing contractor’s side, PVC roof membranes are really great to work with. They’re incredibly flexible, which is great for the installation process, and they have a great track record for longevity and performance. There are some really great benefits for buildings owners as well.
#1 – PVC Roofing is Weldable
#2 – PVC Roofing is Fire Resistant
#3 – PVC Roofing is Environmentally Friendly
#4 – PVC Roofing is Durable
#5 – PVC Roofing is Resistant to Chemicals
Considering a PVC Roofing System?
As you can see, there are a lot of great benefits that go along with installing PVC roof materials for your next roofing project. However like anything else in roofing, not all PVC sheets are created equal. I would encourage you to research the manufacturers and do a little homework on finding a highly skilled roofing professional. Finding a high quality membrane and a skilled roofer will go a long way when you invest in your next roof system.
