Why owners choose TPO
- Heat-welded seams. Seams are fused with hot air, not glued, so they become part of the membrane.
- White, reflective surface. It reflects sunlight, which helps buildings with big cooling loads.
- Fits most roof decks. TPO goes down mechanically attached or fully adhered, depending on the deck and the spec. TPO manufacturer Carlisle rates fully adhered systems highest for durability and wind uplift, while mechanically fastened is the most widely installed.
- The commercial standard. According to Carlisle, TPO is the largest segment of the commercial roofing industry.

TPO or EPDM?
| TPO | EPDM | |
|---|---|---|
| Seams | Heat-welded | Taped and adhered |
| Color | White | Usually black |
| Often best for | Large roofs, cooling loads, new commercial buildings | Repairs to existing EPDM, smaller roofs, additions |
We’ll recommend one after we see the roof and how the building is used. See EPDM roofing.
Tear-off or recover?
The building code doesn’t allow a new roof over an old one that’s water-soaked or deteriorated, or over a building that already has two roofs on it. Even where a recover is allowed, wet insulation underneath has to come out. Our free inspection tells you which applies to your roof, and we photograph what we find.
Restaurant roofs
Grease from kitchen exhaust fans can break down roof membranes. On restaurant roofs, we look at the exhaust fans first and talk with you about grease containment before we recommend a membrane.
How we install a TPO roof
- Deck check. If the old roof comes off, we check the deck. Wet or damaged material gets replaced, not covered over.
- Insulation and cover board. New board gives the membrane a flat, solid base.
- Membrane and seams. Mechanically attached or fully adhered, with every seam heat-welded to the manufacturer’s installation instructions.
- Flashing and edges. Walls, curbs, rooftop units, pipes and drains each get flashed, and edge metal finishes the perimeter.
- Cleanup. Debris goes out every day at our cost, with magnetic sweeps over parking lots and walks.
What a TPO roof costs
We quote every TPO roof per project after a free inspection. Size, tear-off, wet insulation, attachment, membrane thickness and rooftop equipment move the number most. Every proposal is one all-inclusive price with permits and sales tax built in.
Payment and warranty
Roofs we contract directly with a building owner are typically billed 75% at signing and 25% on completion. When we’re the subcontractor for a general contractor, we bill through the GC’s pay-application process. You can pay through the online invoice link, by check or in cash.
Our one-year workmanship warranty starts at substantial completion and covers problems from our installation, not normal wear and tear, damage by others or weather. Membrane and material defects fall under the manufacturer’s warranty, which passes through to you.
Contacted White Rock Construction about checking our roof for possible leaks. He came out the same day and checked it out. After sealing some holes he told us it was probably wind that blew up some shingles allowing the rain to come in. Friendly and honest service.

TPO questions
How long does a TPO roof last?
Carlisle lists manufacturer warranties up to 30 years. Real life depends on the installation, foot traffic and upkeep, which is why we recommend a roof inspection every spring and fall.
Can TPO go over my existing roof?
Sometimes. It depends on how many roofs are already on the building and whether the insulation below is dry. The inspection answers it.
Do you install TPO for general contractors?
Do you install TPO in Illinois?
No. We don’t hold an Illinois roofing license, so all of our roofing is in Indiana.
