On a flat roof, the membrane and its seams do all the work, and that is exactly where TPO earns its place as the flagship single-ply system in our [Austin commercial roofing](https://arproofing.com/austin-commercial-roofing/) lineup. TPO is a thermoplastic membrane welded seam-to-seam with hot air, so the sheet fuses into one continuous surface instead of relying on glue or tape that lets go first. Its reflective white face throws off solar heat rather than soaking it in — and in a Central Texas summer, that shows up on the utility bill. A dark, heat-soaked roof drives a cooling load all day; a bright TPO surface lowers the deck temperature and eases the demand on rooftop HVAC, which matters most on the medical, office, and school buildings that run their air conditioning nine months a year. The other Austin reality is water that does not leave. Flat roofs pond, and standing water after a Central Texas thunderstorm is the failure mode most facility teams inherit and never budget for. The details around every penetration — parapet flashing, HVAC curbs, expansion joints — are where a low-slope roof gives up first, long before the open field of the membrane wears out. ARP has completed commercial roofing work for the Hays County Fire Department and services buildings across the tri-county footprint, and every TPO scope names the drainage and detail work up front instead of discovering it halfway through. ![A GAF EverGuard TPO membrane going down on an Austin low-slope roof — one continuous hot-air-welded sheet, run and supervised by ARP.](https://arproofing.com/_astro/commercial-flat-roof-tpo-installation-aerial-2.CmJ3Mak__gBTk.webp) A GAF EverGuard TPO membrane going down on an Austin low-slope roof — one continuous hot-air-welded sheet, run and supervised by ARP. The Right Fit ## TPO vs PVC vs EPDM for Your Austin Roof TPO is our default recommendation for most Austin commercial buildings, but it is not the only single-ply we install, and the right pick depends on how your building is used. - **TPO** — the flagship. Reflective, heat-welded, and cost-effective across the widest range of Austin retail, office, and institutional roofs. If nothing about your building pushes you elsewhere, TPO is the answer. - **PVC** — the choice for roofs that take grease, oils, or chemical exhaust, like restaurant and commercial-kitchen decks. It welds and reflects like TPO but resists those contaminants, and it runs higher on cost. - **EPDM** — a proven black rubber membrane that handles heavy thermal cycling and ballasted assemblies well. It does not carry TPO's reflective cooling advantage, which is why it is the exception rather than the rule in the Austin heat. The honest version: your building's use, slope, and drainage decide it — not a brochure. ARP walks the roof and tells you which membrane fits your deck. Our [commercial roofing contractor in Texas](https://arproofing.com/commercial-roofing-contractor/) page carries the membrane-by-membrane physics independent of location. ![A reflective white TPO roof carrying rooftop solar — the low-slope surface that throws off the Central Texas heat and gives the equipment a sound, watertight base.](https://arproofing.com/_astro/commercial-flat-roof-solar-panels-tower.Caw7E_N7_ZD7wmy.webp) A reflective white TPO roof carrying rooftop solar — the low-slope surface that throws off the Central Texas heat and gives the equipment a sound, watertight base. Installed Cost ## What TPO Roofing Costs in Austin Installed TPO in Austin runs about $28,000 for a small 2,500-square-foot flat roof up to roughly $222,500–$334,000 on a 20,000-square-foot building — sized by roof area and system. PVC and EPDM run higher. Every number below includes a written scope. TPO is priced two ways at once: by how much roof you have, and by what the deck and drainage underneath actually need. A larger building carries a larger total — there is no per-building flat fee. The ranges here are for a complete, installed GAF EverGuard TPO system on an Austin roof; PVC and EPDM sit adjacent and run higher. | Austin TPO — installed by building size | Range (TPO) | | --- | --- | | 2,500 sq ft flat roof | $28,000 – $41,500 | | 5,000 sq ft flat roof | $55,500 – $83,500 | | 10,000 sq ft flat roof | $111,500 – $167,000 | | 20,000 sq ft flat roof | $222,500 – $334,000 | *Updated September 2026 — Austin market pricing. Every estimate includes a written scope and deck inspection; final price depends on your existing roof, deck condition, drainage, insulation, and roof access. PVC and EPDM systems run higher than the TPO ranges shown.* What moves your number inside those bands is deck condition, insulation, the scuppers and drains a new membrane warranty requires, and rooftop-unit access. ARP measures it and hands you an itemized scope after a free roof inspection & estimate — the number you approve is the number you pay.

How ARP Installs ## How ARP Installs and Services Your Austin TPO Roof Three steps, and you know what is happening at each one. 1. **Assessment and condition report.** ARP walks and photographs your roof and delivers a written report — deck, drainage, seams, and flashing named up front. If the membrane is weathered but the deck is sound, we will tell you a coating may extend it instead of a tear-off; see [Austin commercial roof coatings](https://arproofing.com/austin-commercial-roof-coatings/). 2. **Written scope and a fixed number.** You get an itemized scope before anyone signs. ARP handles permitting where required through the City of Austin and the applicable county jurisdiction, and coordinates inspection timing so it does not stall the job. 3. **Supervised install and warranty registration.** One ARP project manager runs the job from first walkthrough through manufacturer warranty registration, with work phased around your tenants and operating hours. If a leak is isolated, an [Austin commercial roof repair](https://arproofing.com/austin-commercial-roof-repair/) may be all you need; if the membrane is past saving, we scope a full [Austin commercial roof replacement](https://arproofing.com/austin-commercial-roof-replacement/). You get the depth of an established regional roofer backing your local Austin building.

The best way to judge any Austin contractor — us or anyone else — is to ask for a written scope, ask who your single point of contact is, and ask when the manufacturer warranty gets registered in your name. If a roofer can't answer those three plainly, that's your answer. Yes — we're a match ### A good fit if you - Want a roofer your Austin neighbors have actually used — not a pop-up tent after the last hailstorm. - Want everything documented and in writing, with photos, before any crew gets on the roof. - Plan to stay in your Austin home or hold the property long term. - Had recent hail or wind damage and want it documented correctly for your carrier. [Free Inspection & Estimate →](https://arproofing.com/book/) No — we'll say so up front ### Not the right fit if you - Need a commercial job below our minimum repair scope, or a firm residential repair price over the phone — we quote every repair after an on-roof inspection. - Need someone to start tomorrow with no inspection. - Are choosing purely on the lowest bid, without reading the scope underneath it. - Want a contractor to pay, waive or "take care of" your deductible — a criminal offense in Texas under Business & Commerce Code § 27.02. We'd rather tell you that on the phone than waste a walkthrough.

TPO is a thermoplastic single-ply membrane welded into one continuous sheet with hot air, then fastened or adhered over insulation on a low-slope roof. Single-ply is the standard for flat commercial roofs because the membrane flexes with daily heat cycling and the welded seams stay watertight far longer than the glued or taped joints of older built-up systems. ### How does TPO compare to PVC and EPDM in Austin? TPO is our flagship and fits most Austin buildings — reflective, welded, and cost-effective. PVC is the pick for grease- or chemical-heavy roofs like kitchens and runs higher. EPDM is a proven black rubber membrane but lacks TPO's reflective cooling edge, which matters in the Texas heat. Your building's use and drainage decide it; ARP tells you which after walking the roof. ### How long does a TPO roof last in Central Texas? A properly installed TPO roof commonly lasts 20 to 30 years, even under a full Central Texas UV and heat load. The reflective surface lowers the membrane's daily temperature and the heat-welded seams take the expand-and-contract cycling far better than glued ones. Install quality and drainage decide the rest — a roof that ponds ages faster than one that sheds water cleanly. ### Can you repair our TPO membrane instead of replacing it? Often, yes. If the damage is isolated — a punctured membrane, a failed seam, or flashing at an HVAC curb — a flat-priced repair usually solves it without a tear-off or a tenant shutdown. If the deck or insulation underneath is wet, or the membrane is failing across the field, replacement is the honest call. ARP scopes it either way after a moisture-checked [Austin commercial roof repair](https://arproofing.com/austin-commercial-roof-repair/) assessment. ### Is a white TPO roof worth it for cooling costs in Austin? For most Austin buildings, yes. A reflective white TPO surface throws off solar heat instead of absorbing it, so the deck runs cooler and your rooftop HVAC works less through a long cooling season — real savings on medical, office, and school buildings that condition air most of the year. It is not a guaranteed dollar figure; the actual benefit depends on your insulation and how hard your units run. ### Are you a flat roofing contractor serving Austin commercial buildings? Yes — ARP is a flat roofing contractor and low-slope work is the core of what we do across Travis, Williamson, and Hays Counties. Our flagship is GAF EverGuard TPO single-ply, and we also install PVC and EPDM membranes, restoration coatings, and low-slope commercial metal.
