TPO Commercial Roofing Systems in Los Angeles
Old flat roofs develop leaks at seams, around penetrations, and wherever ponding water sits too long. Tar patches and temporary fixes buy time, but they don't fix the underlying problem.
TPO membrane creates a continuous, heat-welded surface that eliminates seam failures. Our crews install it right - proper welds, secure attachment, and detailed flashing work that keeps water out for decades.
"Our warehouse roof was a constant headache. Two years after their TPO install, not a single leak."

How We Install TPO Roofing
Every step matters for flat roof longevity.
Surface Evaluation
We assess your existing roof structure, drainage patterns, and any penetrations that need custom flashing.
Preparation Work
Old roofing removal (if needed), surface repair, and insulation installation. We create the flat substrate TPO requires.
Membrane Installation
Membrane rolls out, seams get heat-welded, and all penetrations receive detailed flashing. No exposed fasteners to leak.
Quality Testing
We test every weld seam and inspect all transitions. You get documentation of the work for your records.
What Does TPO Roofing Cost in LA?
TPO installation typically runs $6-$12 per square foot installed, depending on insulation requirements, roof access, and penetration complexity. Commercial projects with many HVAC units or skylights require more flashing work and cost more per square foot. Tear-off of existing roofing (if required) adds to the base price. We provide detailed proposals breaking down materials, labor, and any structural work needed.

The Flat Roof Solution LA Needed
Flat and low-slope roofs are everywhere in Los Angeles - from mid-century modern homes to commercial buildings across the basin. TPO (thermoplastic polyolefin) membrane has become the go-to solution for these structures, and for good reason: it reflects UV radiation, handles ponding water, and welds into seamless sheets that eliminate the leak points that plague older flat roof systems.
But TPO is only as good as its installation. Seam welds need precise temperature control. Membrane needs proper attachment to handle wind uplift. Flashing details around roof penetrations require attention that separates quality installs from leaky ones. We've installed TPO across commercial and residential properties throughout LA, and we understand the details that make these roofs perform for 20+ years.
