How long does TPO actually last?

20-30 years is typical when installed correctly. Premium 80-mil TPO with proper seam welds regularly reaches 30+ years. Older flat-roof systems (modified bitumen, EPDM) were 12-20 year systems — TPO is meaningfully better.

What about hail on TPO?

TPO is hail-resistant but not hail-proof. Severe hail can puncture the membrane, which requires localized patching. Insurance typically covers hail damage on TPO if documented.

Can TPO be repaired, or do I need to replace the whole thing?

TPO is readily repairable — individual patches heat-weld into the existing membrane. Most TPO leaks are repairable without full replacement. Full replacement usually means the whole system has reached end of life, not one failed spot.

Do you do commercial TPO, or just residential?

Both. Commercial TPO is most of our flat-roof work. See our Commercial Roofing page for commercial-specific process and terms.

Flat Roof Systems

TPO flat roof systems for commercial and low-slope residential.

Low-slope and flat roofs need different systems than sloped residential. TPO is the modern standard — single-ply, heat-welded seams, 20-30 year life, excellent UV resistance.

What we do

Friendly Restoration Services installs TPO (thermoplastic polyolefin) flat roof systems for commercial properties and low-slope residential in Central Texas. TPO is a single-ply membrane with heat-welded seams, 20-30 year typical life, and excellent UV and heat resistance — the modern replacement for older tar-and-gravel and modified bitumen systems.

Flat roofs (typically anything under 2:12 pitch) can't be shingled — water pools and finds its way through any seam. They need a waterproof membrane system, and modern practice is TPO: a white, single-ply thermoplastic membrane that's mechanically fastened or fully adhered to the substrate, with heat-welded seams creating a continuous waterproof layer.

TPO advantages: reflective white surface reduces heat gain (important for Central Texas), ENERGY STAR rated, heat-welded seams eliminate the weak adhesive joints that failed older EPDM and modified bitumen systems, 20-30 year expected life, and individual panel repairability.

We install TPO on flat residential additions, commercial buildings, and low-slope portions of larger structures. Installation involves substrate prep (often including insulation board), mechanical fastening of the membrane, heat-welding of seams, and detail work around penetrations. Commercial TPO installs typically run 2-5 days depending on size.

How it works

From inspection to final walkthrough.

Substrate Assessment

We inspect existing roof condition, check for moisture in insulation, and determine whether full tear-off or overlay is appropriate.

Insulation + Membrane Spec

TPO thickness (45, 60, or 80 mil), insulation R-value, and fastening pattern determined per the project.

Install + Seam Weld

Mechanically fasten or fully adhere the membrane. Heat-weld all seams to create a continuous waterproof layer.

Detail Work + Warranty

Flashing at penetrations, parapet walls, and drains. Manufacturer warranty registered (typically 15-25 years).

Frequently Asked

Flat Roof Systems (TPO) — your questions, answered.

Yes, for genuinely flat or very low-slope additions. Shingles don't work under about 3:12 pitch — they leak. TPO is the right call for flat additions, rooftop decks, and commercial-style residential.
