Charleston Roofing: Article About Pvc Commercial Roofs
Multi-purpose PVC pipe has long been a favorite material for do-it-yourself enthusiasts. Its durability, light weight and cheap availability make it a versatile and handy product. Few people outside of the commercial roofing industry, though, know that PVC can be manufactured into a sturdy, relatively inexpensive single-ply membrane for flat and low-slope roofs.
In fact, PVC has become one of the most popular roofing materials around, delighting business customers for its cost-effective properties and pleasing Charleston roofing professionals with its concise installation and performance. PVC, along with several other thermoplastic membranes such as TPO, make up the fastest growing sector of the nation's roofing industry. With its many benefits, PVC may be a strong contender for your next roofing system.
Polyvinyl chloride, or PVC, differs in a few important ways from the classic white pipes used in home improvement projects. Manufactured into sheets of roofing membrane, PVC contains stabilizers, plasticizers and other materials to create a flexible and strong membrane. Usually white or gray, PVC roof membranes are a single-ply application available in a number of colors and sizes, giving it a unique versatility.
Cost is also a strong selling point for PVC roofing systems. Usually comparable in price to the other single-ply roofing membranes EPDM and TPO, PVC can be slightly more expensive but more effective in its factory-reinforced form.

Since it's a single-ply roofing membrane, the roof is installed relatively easily, providing extra savings on installation.
It's stellar performance on commercial rooftops across America is equally compelling. PVC membranes provide outstanding puncture resistance, can withstand heat and are extremely resistant to bacterial growth. Even more attractive, some PVC roof manufacturers can pre-fabricate a customized PVC roof system to fit your roof's curbs, protrusions and walls, creating a nearly-continuous sheet of roofing that has very few seams.
Seams are a common weak point on most commercial roofs, but the few seams on PVC roofs are extremely durable. Like TPO roofs, PVC roof seams are fused together by heat, creating super-strong connections. Because the PVC is more flexible than TPO, many roofers believe that PVC seams fuse together more easily and solidly than TPO seams.
In spite of these considerable PVC benefits, there are some disadvantages to consider, particularly if you are covering an old asphalt roof. PVC cannot come into contact with asphalt-based products. As a result, if you are replacing an asphalt roof, your roofing contractor will need to install separator sheets on top of the asphalt roofing before the PVC membrane can be applied. The same is true for any roof components that contain asphalt.
Choosing a commercial roof involves a host of factors, including cost, performance and installation ease. Thanks to the technological advances in the commercial roofing industry, you have a variety of options available, including the sturdy and cost-effective PVC.
