60 mil vs 80 mil TPO — which should I install?

60 mil handles most office and retail. 80 mil is worth the upgrade for buildings with rooftop foot traffic, frequent equipment maintenance, or 25-year warranty targets.

Can TPO be repaired easily if damaged?

Yes — TPO patches heat-weld to existing membrane permanently. Punctures are repaired in minutes with proper equipment.

How does TPO compare to EPDM?

TPO is white and reflective; EPDM is black and absorbs heat. TPO welds; EPDM splices with primer and tape. Both perform well — selection often comes down to budget, warranty preference, and energy goals.

What warranty terms are available?

15-, 20-, and 25-year system warranties (material + labor) on qualifying installs by certified contractors. We hold those certifications.

About TPO Roofing

TPO is the most-installed commercial single-ply membrane in the U.S. for a reason: bright white cool-roof surface, heat-welded watertight seams, and long manufacturer warranties when installed by certified contractors.

We install 60 and 80 mil TPO from Carlisle, Versico, GAF, and Johns Manville. Membrane thickness selection depends on traffic load and warranty target — 60 mil for typical office/retail, 80 mil for buildings with rooftop traffic, equipment maintenance, or longer warranty terms.

Every seam on a TPO roof is heat-welded with a hot-air gun and probed for weld continuity. Properly welded seams are functionally watertight for the life of the membrane — far more reliable than the adhered or taped seams used on older single-ply systems.

TPO's white surface reflects 70%+ of solar radiation, materially reducing summer cooling loads on buildings with significant rooftop exposure. Combined with tapered insulation upgrades during install, energy savings often pay back a meaningful share of the roof investment over its life.

Our process

01
Substrate prep & insulation
Existing membrane removed or recovered, insulation installed or upgraded per code and warranty requirements.
02
Mechanical attachment or full adhesion
Membrane attached per system spec — mechanically fastened plates or fully adhered depending on building and wind zone.
03
Heat-welded seams
Every seam hot-air welded and probe-tested for continuity before close-out.
04
Manufacturer inspection & warranty
Manufacturer rep walks the roof for system warranty registration — both material and labor coverage.
