TPO Roofing Systems

TPO Roofing Membranes come in mils of .45, .60, .72 & .80.

The smooth surface of TPO resists dirt pick-up and biological growth compared to other thermoplastic membranes.


Fully Adhered Systems:

  1. Insulation boards are mechanically attached to the substrate.
  2. The membrane and substrate are coated with a bonding adhesive.
  3. The membrane is rolled into place
  4. Seams are hot air welded.

Mechanically Attached Systems:

  1. Insulation boards are fastened to the substrate.
  2. Fasteners and plates are used to mechanically fasten membrane.
  3. Membrane sheets are overlapped and joined together by hot air welding.

Robot Welder:
Welded seams are much stronger than glued or taped seams.

If TPO is not a flat roofing option for you, we also provide EPDM (ethylene propylene diene monomer) which comes in 45 & 60 mil thickness.

We also do flat roofing repairs!
