  • Cost: $$
  • Lifespan: 10-20 years
  • Color Options: Typically white, gray, or tan. Additional colors are available.
  • Composition: Thermoplastic Olefin or Polyolefin
  • Advantages: Lightweight. Low maintenance. Monolithic covering. High UV, ozone, and chemical resistance. Membrane flexibility. Fire resistant. Energy Star Certified. Performs with ponding water.
  • Disadvantages: Less resistance to punctures. More difficult to repair as it ages. Some issues with animal fat compatibility.

TPO roof systems are becoming a more popular choice for businesses in North Carolina. These single ply membranes — constructed from ethylene propylene rubber — are designed to combine the durability of EPDM rubber with the proven performance of heat welded seams.


TPO can be loosely laid, fully adhered, or mechanically attached:

  • Loose Laid: Ballast, such as river rock or pavers, are used to hold the membrane in place.
  • Fully Adhered: The membrane is glued in place using commercial grade adhesives rolled on both the backside of the membrane and the substrate.
  • Mechanically Attached: Screws and plates are used to hold the membrane in place. This approach is recommended because it prevents water migration under the membrane in case of a puncture.
