TPO (thermoplastic polyolefin) is one of the most common flat roof systems on commercial buildings today. It comes in wide rolls, the seams are welded together with hot air instead of glued, and the white surface reflects much of the sun's heat instead of soaking it up.
Why owners choose TPO
- Cooler building. A reflective white roof can cut heat gain through the roof, which helps air-conditioning costs in our climate.
- Strong seams. Heat-welded seams become one continuous piece of membrane.
- Fewer seams. Wide rolls cover large roofs with fewer joints.
- Repairable. Punctures and damaged areas can be patched by welding new membrane in place.
How we install it
- Remove the old roof down to a sound deck, or evaluate whether a recover is allowed and makes sense.
- Install insulation, including tapered insulation where water needs help reaching the drains.
- Attach the membrane to the Miami-Dade approved (NOA) or Florida Product Approval method for your building, including the extra fastening needed at corners and edges in high-wind zones.
- Weld and probe-check every seam.
- Flash curbs, AC stands, walls, drains and penetrations, then install metal edge and coping.
GAF EverGuard® TPO
Our go-to TPO line is GAF's EverGuard®. Standard EverGuard TPO comes in 45, 60 and 80 mil. EverGuard Extreme® TPO is GAF's enhanced-weathering version, made for high heat and strong UV, and comes in 50 to 80 mil. For our climate it's usually worth the upgrade. Fleece-back versions add puncture resistance, and self-adhered EverGuard SA avoids adhesive fumes on occupied buildings. Installed as a complete GAF system, the roof can qualify for a GAF commercial guarantee. Ask us which options apply to your building.

TPO Roofing FAQ
How long does a TPO roof last in Florida?
A well-installed TPO roof commonly lasts around 15 to 25 years, depending on membrane thickness, drainage, foot traffic and maintenance.
Can TPO go over my existing roof?
Sometimes. Code limits how many roofs can be stacked, and a recover only makes sense if the existing roof and insulation are dry. We check with core samples before recommending it.
Is TPO good for hurricanes?
It performs well when it's installed to an approved system with the correct fastening pattern for the building's height and wind zone. That's what we install.
