Thermoplastic Polyolefin

Thermoplastic polyolefin (TPO) membranes is one of the most popular commercial roofing materials. These single ply membranes are created by using reinforcing fabric and rubber together with state-of the art technology to be considered an environmentally safe, “green” product. TPO roofing membrane is typically installed using mechanical fasteners and plates placed along the edge of the sheet and fastened through the membrane and into the roof decking. Adjoining sheets of TPO membrane are overlapped, covering the fasteners and plates, and joined together with a hot air weld. This type of system is highly resistant to wind and other weather factors.

Advantages of TPO Membranes

  • Excellent elongation and flexibility
  • Lightweight; great for use as a recover system
  • Because no aggregate surfacing is necessary, maintenance and repairs are easily accomplished
  • Available in colors
  • Available in .045 mil, .060 mil, .090 mil and .120 mil to meet every need.
  • Long term warranties available
  • Fast track system for time sensitive projects

System Design Considerations

  • Roof must have positive drainage
  • Roof should not be expected to be used as a traffic surface
  • Buildings venting any type of contaminate onto the roof surface should incorporate grease traps or recovery systems
