Cool Vinyl Roofs Quell Fire

Vinyl roofing membranes are inherently fire resistant. Polyvinyl chloride (vinyl or PVC) is a naturally fire resistant polymer – a distinction between it and all other roofing plastics. Vinyl roofing membranes contain additional fire retardants, making this cool roofing material slow to catch or spread fire – and self-extinguishing when the source of heat or flame is removed. To see for yourself, view a dramatic fire test conducted by Southwest Research Institute's Fire Technology Department.

The test compares the behavior of three common commercial single-ply roofing materials – vinyl or PVC, TPO and EPDM – after they are ignited by a Bunsen burner flame.

In the test, the vinyl roofing sample self-extinguishes in seconds (13 in one, 12 in the other) after the flame source is removed, while the other two samples continue to burn for between 3 and 6 minutes apiece before they are completely consumed. Read the full fire-resistant roofing report.

PVC roofs have passed applicable Factory Mutual (FM) and Underwriters Laboratories (UL) tests for Class A and B roof assemblies for high and low slope roof applications. UL and FM ratings are specific to individual roofing membrane manufacturers. Check with each company’s technical department for company-specific ratings.

    “Your [vinyl roofing membrane] performed very well in resisting flame spread when vandals started several fires on our roof. The fires were only discovered when a worker went on the roof the next day. [Vinyl] performs even in ways that I never expected.” – Bill Hamlin
