About PVC Roofs

There are quite a few commercial options available when it comes to new roof installation. Every type will be more appropriate in certain situations, with advantages and disadvantages. One of the more popular options is PVC (Polyvinyl Chloride) material. Here’s a little information about it:

History:

PVC roofs have been a popular choice since the 1970s. Their two biggest rivals, EPDM and TPO roofs, don’t match the quality, life-span, or durability of PVC, but they’re also a little cheaper.

How it’s made:

PVC is easy to make because of the availability of its component materials: ethylene and chlorine. Plasticizers, stabilizers, and pigments are added in during the manufacturing process to add to things like hardiness, color choice, etc. The actual material is made in 2 layers, with a polyester “scrim” in between. The top layer is modified with chemicals that deflect UV damage. When the material is placed on a roof, the seams are hot welded together, which keeps it from being susceptible to leaks.
