Commercial PVC Roofing in Texas: GAF GoldElite Welded Systems

PVC costs more than TPO because it does one thing TPO can't: it stands up to grease, animal fats, oils, and chemical exhaust without breaking down. Both membranes are hot-air-welded thermoplastics in the commercial single-ply roofing family, so you get the same monolithic, watertight seams either way, and PVC just adds a chemistry that survives what a rooftop kitchen or industrial exhaust fan throws at it.

Here's the thing most single-ply bids skip. The seam is where flat roofs live or die, and welding beats gluing every time: you're fusing two sheets into one continuous surface instead of trusting an adhesive to hold. TPO and PVC both weld. Where they part ways is exposure. Set a TPO roof under a fryer exhaust or a chemical stack and the grease slowly attacks the membrane; set PVC there and it shrugs it off. That's the premium you're paying for, and if your building has no grease or chemical exposure, you probably shouldn't pay it. On a clean office or warehouse, TPO gives you the same welded performance for less.

PVC earns its keep in three places:

• Grease and chemical resistance. The reason PVC exists in commercial roofing. Restaurant exhaust, food-processing discharge, and industrial fumes that would age a lesser membrane don't faze it.
• Ponding tolerance. PVC handles standing water better than most single-ply. On a low-slope roof where drainage is imperfect and water sits after a storm, that matters.
• Reflective, fire-rated surface. Like TPO, a white PVC membrane reflects heat instead of soaking it up, which shows up on your summer cooling bill on a big footprint.

PVC is one branch of ARP's broader commercial single-ply roofing lineup, installed as GAF EverGuard PVC, part of the GAF single-ply family.

Your building tells you whether PVC is the right call, not your budget. If there's grease, animal fat, or chemical exhaust hitting the roof, PVC is the membrane. If there isn't, a reflective TPO roof usually does the same job for less money.

The buildings where PVC pays off:

• Restaurants and commercial kitchens. Fryer and hood exhaust deposits grease across the roof around every vent. PVC resists it; most other membranes slowly surrender to it.
• Food processing and grocery. Animal fats and processing discharge are hard on ordinary single-ply. PVC is engineered for exactly this.
• Industrial buildings with chemical exhaust. Manufacturing, labs, and plants that vent solvents or chemical fumes onto the roof need a membrane rated to take it.
• Low-slope roofs that pond. Where drainage isn't perfect and water stands after rain, PVC's ponding tolerance buys you service life.

We've walked restaurant roofs where a five-year-old membrane was already failing in a grease-shadow around the kitchen exhaust: the rest of the roof looked fine, but the section under the fumes was cooked. That's the failure PVC is built to prevent. If your building doesn't have that exposure, we'll tell you honestly that PVC is more membrane than you need, and point you at the system that fits.

Commercial PVC roofing in Texas runs $14.00 to $20.00 per square foot installed. A 10,000-square-foot building typically lands between roughly $184,000 and $262,500, depending on your deck condition, drainage, and rooftop access.

Commercial PVC roofing in Texas runs $14.00 to $20.00 per square foot installed. Final price depends on your existing roof condition, deck substrate, drainage requirements, and rooftop access, which is why every figure below is a range, not a quote.

Updated July 2026, Texas market pricing. Every commercial estimate we write includes a full roof assessment with photos, a written scope before you sign, manufacturer-specified installation, and a final walkthrough. PVC sits at the top of the single-ply range, above TPO and EPDM, because you're buying chemical resistance, not just a watertight roof. For sample project totals by building size and a full breakdown, see the single-ply roofing cost guide, and for the head-to-head, read TPO vs PVC vs EPDM.

You get three steps, not a mystery. Here's how a PVC project runs from your first call to your warranty paperwork.

1. Free assessment and written scope. We walk your roof, core-sample where needed, document condition with photos, and hand you a written scope (membrane, mil thickness, attachment method, flashing detail at every curb and penetration, and drainage corrections) before you sign anything.
2. Hot-air-welded installation, supervised. Your PVC membrane goes down to GAF EverGuard specifications by vetted installation partners we deploy and supervise, with an ARP project manager on the job. Every seam is hot-air-welded and probe-tested, and you get photo documentation at each stage.
3. Final walkthrough and warranty registration. We inspect the finished system with you, confirm every weld and penetration, clean the site, and register your manufacturer warranty. You end with a documented roof and a paper trail you can hand to ownership.

One line an honest PVC scope always spells out: new scuppers and drains. A new PVC membrane almost always needs new drainage, and reusing old scuppers and drains under a fresh membrane is technically unsound, because those aged connections are where leaks start. Positive drainage is a warranty condition for many single-ply manufacturers, and it matters even more on the low-slope, ponding-prone roofs PVC is chosen for, so we carry scuppers and drains as an itemized line rather than leaving warranty-required drainage off the bid to look cheaper. When you compare PVC quotes, check whether new drainage is actually in the competitor's scope.

When you sign a commercial roof contract, you're not hiring a logo. You're hiring a certified installer, a documented process, and a company that will still answer the phone when the warranty question comes up in year fifteen.

• The right certification for the membrane. ARP Roofing is a GAF GoldElite Commercial Contractor, GAF's top commercial designation, and the umbrella certification that covers GAF EverGuard PVC single-ply. We're also an Elevate Red Shield Licensed Contractor and a UNIFLEX Premier Elite Contractor, and we're registered with every municipality where we work. The certification is what unlocks the manufacturer warranty in your name.
• A COO who reads roofs for a living. Randal Williams is a former commercial high-rise field engineer and Xactimate expert with 15+ years in roofing and construction. He has scoped and documented more than $7 million in insurance claim work across Texas, including single commercial claims above $2 million, supporting property managers and building owners through the claims process as the contractor of record. On a PVC job, that field-engineering eye is the difference between a membrane spec'd for your building's exposure and one spec'd for the contractor's convenience.
• One point of contact and a documented job. Your ARP project manager runs the schedule, coordinates the permit, and delivers photo documentation from assessment through warranty registration, the record you hand ownership when they ask how the roof is holding up.

Every commercial roof I've ever seen leak was telling the owner something about its design or its install months before the first drip showed up inside. Leaks are the last symptom, not the first. The contractors who fix the drip and leave are the reason you're still getting drips.

PVC is a long-term specification decision, so here's the honest read on who we serve well, and who we don't.

You're probably the right fit if you...

• Manage a restaurant, commercial kitchen, food-processing, or industrial building with grease or chemical exhaust on the roof
• Have a low-slope roof that ponds and need a membrane that tolerates standing water
• Want a written scope of work and photo documentation before anyone touches the roof
• Want the membrane matched to your building's actual exposure, not a contractor's default system
• Are holding the building long-term and want a partner, not a one-off vendor

You're probably not the right fit if you...

• Run a clean office or warehouse with no grease or chemical exposure; honestly, TPO will likely give you the same welded performance for less
• Need the lowest bid in the market, a respected decision we can't always match
• Need work to begin within 24 hours with no inspection or documentation
• Manage a building under 1,000 sq ft, where our minimum scope makes the economics work against you

• ASTM D4434: the material standard behind PVC single-ply membrane referenced in the systems overview.
