TPO, or thermoplastic polyolefin, has become the dominant flat roofing system for commercial properties in San Antonio for good reason. It handles the heat, performs efficiently, and holds up long-term when it's installed correctly. The catch is that TPO is only as good as the installation behind it: a seam that isn't properly heat-welded, a drain that isn't flashed correctly, or a membrane that's undersized for the roof are the failure points that turn a reliable system into a maintenance headache.
USA Home & Commercial has installed and repaired TPO systems on commercial properties across San Antonio and Central Texas for more than 20 years. We evaluate membrane condition, seams, penetrations, flashing, insulation, and drainage before recommending a repair or replacement. On a low-slope roof, installation details matter because even a small failure can lead to interior damage, operational disruption, and liability exposure.
We work with property managers, building owners, and developers on TPO projects ranging from small commercial strip centers to large multifamily complexes. Every project starts with a proper assessment, not a sales pitch.
20+ years, 200+ five-star reviews, and residential and commercial credentials from leading manufacturers and industry programs.
Answers about how TPO performs, how long it lasts, and how it compares to PVC.
We install and repair TPO, PVC, modified bitumen, metal and roof coating systems. TPO and modified bitumen are the most common on San Antonio commercial buildings. The right system depends on the roof's slope and drainage, foot traffic from rooftop equipment, what gets vented onto the roof, and how long the owner plans to hold the property. The written bid explains the options and the warranty each one carries.
We trace it on the roof, not from the ceiling stain. On a low-slope roof, water often gets in at a seam, flashing, penetration or drain some distance from where it shows up inside. We check the membrane, seams, curbs and drains upslope of the leak, photograph what we find, and take a core sample if we suspect wet insulation. The repair then fixes the cause, and you get photos of the problem and the finished work.
Often, yes. Building code allows a new roof over one existing roof as long as the existing roof is dry, sound and well attached. If there are already two roofs, or the insulation underneath is wet, the old roofing has to come off down to the deck. We take core samples to check before we recommend a recover. When a roof qualifies, recovering can save up to 30% compared with a full tear-off.
A new roof carries two warranties: the manufacturer's warranty on the roofing system and our workmanship warranty on the installation. Our workmanship warranty runs 10 to 25 years depending on the system and transfers to the new owner if the building sells. On TPO, PVC, modified bitumen, metal and other low-slope systems, we also offer manufacturer NDL (no dollar limit) warranties. Terms are written into your bid before you sign, and at closeout we register the manufacturer warranty and hand over the documentation.
TPO (thermoplastic polyolefin) is a single-ply membrane, usually white, used on flat and low-slope commercial roofs. Its seams are heat-welded into one continuous sheet, and the reflective surface helps with San Antonio heat. It's mechanically fastened or fully adhered over insulation, in thicknesses such as 45, 60 or 80 mil depending on the building and the warranty.
It depends mostly on installation and upkeep. Thicker membranes, properly welded seams, positive drainage and regular maintenance add years, while ponding water, foot traffic and poorly flashed penetrations take them away. The manufacturer's warranty term is a good guide to what a given system is built for, and we include it in the bid.
Both are white, heat-welded single-ply membranes. PVC holds up better to grease and chemicals, which makes it the usual choice for restaurants and buildings with kitchen exhaust on the roof. TPO typically costs less and performs well on most other commercial buildings. We recommend one or the other based on what the roof is exposed to.
TPO is only as good as its seams. Poorly welded seams, punctures from foot traffic, and flashing details that aren't sealed properly are where most TPO leaks start. It also isn't the right membrane where grease is vented onto the roof; PVC is. Careful installation, walk pads around equipment and routine inspections handle most of these risks.
