PVC Roof Systems

PVC stands for Polyvinyl Chloride. It is one of the pioneering single-ply roof materials. The first known PVC roofing membrane was produced by a company called Trocal and was installed in Germany in 1966. Within a few short years, Trocal PVC covered millions of square feet all over the world and single-ply roofing was setting the stage for market dominance.

PVC roofing comes in a variety of thicknesses ranging from 40mil to 80 mil. There are fleeceback materials (PVC membrane with a fuzzy underside) that go up to 115 mils. They’re actually the standard thicknesses (50, 60, and 80 mils) with the fuzzy backing adding to it which makes it thicker. Fleeceback systems can be installed in asphalt or adhesive adding to the products versatility.

PVC roofs are installed in three different ways:

  • Mechanically Attached – the PVC roof is held in place by being attached to the substrate/deck using screws or other types of fasteners, depending on the deck type.

  • Fully Adhered – the PVC roof is attached to the substrate using special adhesive (glue). There are different adhesive options but that’s not something most readers will care about.

  • Ballasted – the PVC roof is laid across the roof loosely, secured only at the roof perimeter and around roof penetrations such as pipes, air conditioning units, etc., and held in place with ballast which usually consists of smooth river rock although other options are available.

Regardless of how the roofs are installed, the seams of all three systems are sealed the same way, using a hot air welder. The strength of the seams allows the manufacturer to warrant PVC roofs with ponding water.
