TPO is a single-ply roofing membrane. It is made up of ethylene propylene rubber. This roofing material has the durability of EPDM rubber and the proven performance of PVC hot-air weldable seams. These seams are reportedly 3 to 4 times stronger than adhesive and tape seams. TPO material is environmentally friendly and safe to install. It has a flexibility characteristic that allows for building movement without the failure of the TPO roofing system.



TPO is algae resistant. It has excellent resistance to ozone, tears, impacts, and punctures.



TPO roofing membranes are available in white, light grey, and black. The most common thicknesses used are 45mil and 60mil.



TPO roofing membrane can be installed in 3 ways:

  • Fully Adhered
    • With this, the roof is glued to the substrate with a special adhesive. This adhesive creates a chemical bond with the membrane.
  • Mechanically Attached
    • This method uses special screw-type fasteners to secure the membrane. The fastener type will depend on the type of substrate on the roof.
  • Ballasted / Loose-Laid
    • The membrane is loose-laid over the roof. It is sealed around the perimeter of the roof and around all penetrations. Ballast such as river rock is laid on top to hold the membrane down.

Service Life

The key to a long TPO roof life with any roof is a proper installation and regular checkups. TPO roofing membranes can have manufacturer full systems warranties from 5 to 30 years.

In addition to the up to 30 year manufacturer full system warranty additional warranties can be obtained.  Versico offers TPO Roof warranties for wind speeds up to 120 miles per hour, accidental puncture and a warranty that covers up to 2″ in diameter hail.
