The PVC Advantage

PVC roofing membranes are superior roofing materials for many reasons:

Vinyl is inherently flame resistant

  • Most vinyl membranes will not support a flame when the fire source is removed.
  • High flame resistance can make it easier for PVC roofing systems to attain Class-A fire ratings than for other roofing systems.
  • Combustion, especially incomplete combustion, is a source of many environmental toxins (backyard refuse burning and residential wood burning are two major sources).
  • A roof membrane that doesn’t burn is less likely than a flammable roofing material to emit potentially harmful substances.

PVC membranes are flexible

  • Most PVC membranes are very flexible and can be easily customized to accommodate rooftop variances.
  • Some vinyl roofing systems are custom-made (prefabricated) to fit each building. Customization can reduce the potential for scrap and waste at the job site.

Vinyl membranes are lighter in weight than other roofing systems

  • Vinyl roof membranes typically add very little weight to an existing structure.
  • In a re-roof situation, a PVC roof can often go directly over the existing system. This avoids costly tear-offs, meaning no asphalts, felts or other old roof materials go into landfills.

PVC membranes are heat-weldable

  • PVC membranes can be heat-welded, which produces the strongest and most reliable seams. Reducing the potential for leaks to occur also reduces the possibility for interior dampness and subsequent mold to develop.
  • Some vinyl membranes use two-way venting, which allows the roofing system to “breathe” and can reduce the potential for trapped moisture.

Vinyl roofs can be highly reflective

  • Some vinyl roofs are highly reflective, keeping buildings cooler, reducing energy demand, and helping mitigate urban heat island effects. Cooler cities reduce dependence on limited natural resources.

PVC is highly-resistant to most chemicals

  • Most PVC membranes will provide long-term service in the harsh environments experienced on rooftops.
  • Many vinyl roofs are still functioning after more than 30 years of service. A longer-lasting roof means less frequent roof replacements over the life of a building. A building lasting 100 years may go through 8-10 “Type-X” roofs, but only 3-4 vinyl roofs.

Vinyl is easily recycled

  • During the production of some PVC roofing systems, there is virtually no waste because fabrication scrap is reground and re-used in the roofing system or other building components.
  • Unlike many other roofing materials, vinyl membranes can be recycled at the end of their lives on the rooftop.

When selecting a roofing system, remember that PVC membranes are your best choice.
