What TPO roofing is

TPO (thermoplastic polyolefin) is a white or light-colored membrane that comes in large sheets. The seams are heat-welded together, which makes them strong and watertight when they are done right. The light surface reflects sunlight, which helps keep the building cooler in summer.

TPO vs. EPDM

EPDM is a black rubber membrane with glued or taped seams. TPO has heat-welded seams and a reflective surface. Both are common on commercial roofs in western PA. The right choice depends on the building, the existing roof and your budget, and we can walk you through the trade-offs after an inspection.

Common TPO roof problems

  • Seams that were not fully welded and open up over time
  • Punctures from foot traffic, dropped tools or storm debris
  • Failed flashing at curbs, HVAC units, pipes and parapet walls
  • Ponding water near clogged drains
  • Membrane shrinkage pulling at edges and corners

Frequently asked questions

How long does a TPO roof last?

Lifespan depends on membrane thickness, installation quality, and maintenance. Regular inspections and prompt seam repairs help a TPO roof last as long as possible.

Can a TPO roof be repaired?

Yes. Punctures and open seams can usually be patched and heat-welded with new TPO, as long as the existing membrane is clean and in reasonable condition.

How much does TPO roofing cost in western PA?

Cost depends on the size of the roof, insulation, tear-off and details like curbs and drains. Call 814-900-7106 for a free quote.

Can TPO go over an existing roof?

Sometimes. If the existing roof and insulation are dry and the building code allows another layer, TPO can be installed over it. Wet insulation must come off first. An inspection will tell you.

Is TPO better than EPDM?

Neither is better for every building. TPO offers heat-welded seams and a reflective surface; EPDM has a long track record and is easy to repair. We recommend based on the building.
