PVC (which stands for polyvinyl chloride) is a single-ply roofing membrane used on commercial or industrial roofs. Similar to other membrane roofing materials like TPO and EPDM, PVC can be applied over existing roofing materials for an eco-friendly roofing solution.
Is PVC a good roofing material?
It is also chemical resistant and fairly low maintenance, making it an ideal choice for some types of commercial buildings.

How much does a PVC roof cost?
A fair range is between $7.50 and $12.50 per sq. ft. or $750 to $1,250 per square if installed by a PVC expert. For a typical 1,200 square foot flat roof, you can expect a total average cost range between $9,000 and $15,000 for a new PVC roof mechanically attached to a roof deck.
How is PVC roofing installed?
In a ballasted installation, a PVC roofing membrane is laid across the substrate loosely, rather than being fastened or glued in place. The membrane is held in place with a ballast, which is typically made of washed river rock, manufactured concrete pavers, or other materials of substantial weight.
Is PVC roofing durable?
Durability: A PVC roofing membrane has heat-welded seams that create a watertight bond, making it extremely strong and permanent. As a result, PVC roofs do not rely on tapes, adhesives, or caulk for sealing unlike other roofing systems do.
Which is better TPO or PVC?
While TPO has superior weathering and slightly better tear and break resistance than PVC, PVC does have some characteristics that certain customers need or prefer. … Also, PVC is slightly more flexible than TPO, which some contractors like. There used to be talk about welding differences, but both membranes weld well.

How long do rubber flat roofs last?
If installed correctly, you can expect a rubber flat roof to last in excess of up to 50 years. Because an EPDM flat roof is comprised of durable rubber, it can withstand extreme weather conditions such as hail or snow and common weather such as rain and strong winds.
What is the life expectancy of a rubber roof?
One of the longer roofing system lifespans in the study is that of EPDM (rubber) roofs. They can be expected to last 25-30 years. This system is growing quickly in popularity in the US thanks in part to its longer-than-normal lifespan.
