TPO Single-Ply Membrane
Heat-welded thermoplastic polyolefin in a reflective white that cuts summer heat gain. Fully adhered or mechanically attached over rigid insulation. Seams are welded, not glued — which is why TPO outlasts the rolled roofing it usually replaces.

What TPO Single-Ply Membrane Is Covered For
Manufacturer membrane warranties commonly run 15–25 years depending on membrane thickness (45, 60 or 80 mil) and system specification. Backed by our 5-year workmanship warranty.
And our workmanship warranty on top of it
Every Top Dog roof includes a written, transferable 5-year workmanship warranty covering our installation labor — separate from and in addition to the manufacturer’s material warranty.
Manufacturer terms are set by the manufacturer and can change. This reflects published coverage at the time of writing; the certificate we hand you at completion governs, and we register it in your name before we leave. See every warranty we offer →
Where TPO Single-Ply Membrane Makes Sense
Flat and low-slope roofs — porch roofs, additions, dormers and commercial buildings.
Most Pittsburgh roofers install one system. We install five — so the recommendation you get is driven by your roof’s pitch, deck and drainage, not by what happens to be on the truck.

The crew did an outstanding job — extremely clean, highly professional, and impressively efficient. Their communication throughout the project was excellent, keeping me informed at every step. They had repaired my roof last year, and when a severe storm came through, I knew exactly who to call. The owner was on site to check the workmanship, which gave me even more confidence in the quality of the project. The roof looks fantastic, and the entire process was smooth and well-executed. I couldn’t be happier with the results.
