How Much Does Single-Ply Roofing Cost in Texas? TPO, PVC & EPDM

A single-ply roof in Texas runs $8.00 to $20.00 per square foot installed. TPO is the value pick at $8.00 to $12.00, EPDM sits at $11.00 to $16.00, and PVC, the grease-resistant premium, runs $14.00 to $20.00.

Commercial single-ply roofing costs $8.00 to $20.00 per square foot installed in Texas, and the membrane your building calls for decides where in that band you land. If you're pricing a replacement, start with the three systems ARP installs as a GAF GoldElite Commercial Contractor (TPO, PVC, and EPDM), because the material choice moves your number more than almost anything else on the estimate.

Updated July 2026. Texas market pricing.

Here's the four-part version, so the range actually means something to you. The range is $8.00 to $20.00 per square foot across all three membranes. What's in it: a full existing-roof assessment with photos, a written scope before you sign, manufacturer-specified installation, all penetration flashings, and a final walkthrough with you or your facility manager. What moves it: which membrane your building needs, deck and substrate condition, drainage corrections, and rooftop access. The label: these are Texas market numbers confirmed July 2026, and final price still depends on your existing roof condition, deck substrate, drainage requirements, and access complexity, which is what the on-site assessment settles.

A 10,000-square-foot single-ply roof in Texas typically runs $105,000 to $262,500 installed, depending on membrane. Smaller 2,500-square-foot buildings land near $26,500 to $65,500; large 50,000-square-foot footprints reach the high six and low seven figures.

Your per-square-foot rate is only half the math. The other half is how much roof you actually have. A building's flat roof runs larger than its interior floor space once you account for parapets, overhangs, and rooftop equipment, so a "10,000-square-foot building" carries closer to 13,000 square feet of roof. Here's what that turns into as a Texas baseline.

Updated July 2026. Texas baseline pricing. Labor rates, staging, and access vary across the state, so your market can move these figures roughly 3% to 10%, and your assessment sets the exact number. These totals assume a straightforward tear-off and replacement; a lay-over recover over one existing layer typically comes in lower, and heavy drainage or deck repair pushes higher.

Every commercial estimate we write includes the full roof assessment and photos, a deck and substrate condition report, the scope in writing before the contract is signed, all penetration flashings, code-required drainage notes, the building permit, manufacturer warranty registration, and a final walkthrough. No surprise line items on day three.

The three membranes aren't three grades of the same thing. They're different chemistries built for different buildings, and the price gap reflects what each one is engineered to survive. Knowing why the numbers differ keeps you from overpaying for resistance you don't need, or underbuying and putting the wrong membrane over the wrong exhaust.

TPO, your value and reflectivity pick ($8.00–$12.00/sq ft). If you want the lowest sound number without giving up performance, TPO is usually where you land. It's a reflective white thermoplastic membrane that heat-welds into one watertight surface, and that white face bounces heat instead of soaking it up, which shows up on your summer cooling bill on a big-box footprint. According to ENERGY STAR's cool-roof guidance, a reflective roof lowers air conditioning costs and eases peak demand on the grid, and the U.S. Department of Energy's cool-roof acquisition guidance puts the surface-temperature gap at up to 60°F against a traditional black roof. That's real money over a 20-year hold, not a brochure line.

EPDM, your proven-rubber option ($11.00–$16.00/sq ft). When a reflective surface isn't the priority, EPDM earns its place. It's a synthetic rubber membrane, ballasted or fully adhered, with a decades-long track record on low-slope roofs. You're paying for durability and a long, boring service life, not for reflectivity you won't use.

PVC, your grease- and chemical-resistant premium ($14.00–$20.00/sq ft). If your rooftop exhaust carries grease or chemicals (restaurants, commercial kitchens, food processing), PVC is the one membrane that won't be eaten alive by it. You're paying the premium for a membrane engineered to resist animal fats and chemical exhaust that would degrade a lesser sheet. Put it where you need it; skip it where you don't.

Two identical-looking buildings can price thousands of dollars apart, and the difference is almost never the membrane alone. Here's what a real walkthrough is measuring when it sets your number.

• Membrane type and thickness. Beyond the TPO-EPDM-PVC choice, thickness matters: an 80-mil membrane costs more than a 60- or 45-mil sheet, and it buys you more puncture resistance and warranty term. If your roof takes foot traffic or hail, the thicker spec usually earns its upcharge.
• Deck and substrate condition. Your price assumes a sound deck. Wet insulation, a corroded metal deck, or a saturated substrate discovered on assessment adds tear-out and replacement, which is exactly why we core and document before quoting, not after.
• Tear-off versus recover. Building code caps you at two roof layers. If you're on your first layer, a lay-over recover can save you real money over a full tear-off. If you already have two layers, tear-off is the only compliant path, and the disposal is part of the number.
• Rooftop penetrations. Every HVAC curb, drain, pipe, and skylight is a flashing detail that has to be welded and sealed by hand. A roof crowded with equipment costs more to detail than a clean field of the same size.
• Parapet and edge-metal complexity. Tall parapets, expansion joints, and custom edge metal add labor and material. The perimeter is where flat roofs leak first, so it's not a place to cut.
• Drainage and slope corrections. Water that still sits 48 hours after a rain is telling you the drainage isn't working. Tapered insulation or added drains to fix ponding adds cost up front, and prevents the premature failure that costs far more later.
• Access and staging. A single-story building with open parking prices differently than a four-story roof over an occupied tenant space that needs a crane, night staging, and phased work to keep the business below running.
• Warranty tier. A standard manufacturer warranty costs less than an enhanced no-dollar-limit (NDL) warranty, where the manufacturer inspects and backs the full system. On a building you plan to hold 15-plus years, the enhanced tier is usually worth the line item.

If one bid comes in far under the others, something is missing from the scope, not from the price. We've walked buildings where three different roofing companies had been up top in five years, each one shaving the number by skipping the drainage fix, specifying a thinner membrane than the roof needed, welding seams by hand instead of by robot on a big field, or writing "included" flashings that turned into change orders on day three. Same-looking roof, very different outcome at year seven.

The cheapest part of a bad roof is the quote. Everything after that gets expensive fast.

The fix is simple: compare scopes, not just numbers. Ask each bidder to itemize membrane type and thickness, seam method, flashing details, drainage corrections, tear-off versus recover, and warranty tier. When the scopes match, the honest low bid is a fair deal. When they don't, the cheap number is usually buying you a second roof sooner than you planned.

There's no calculator that can price a commercial roof from the curb. The number comes from what we find on the roof, in writing, before you commit a dollar. Here's the three-step path from question to quote.

1. We assess and document. A project manager walks your roof, cores where needed, photographs the deck, drainage, penetrations, and edge conditions, and identifies which membrane fits your building and how it's holding up today.
2. We scope and price it in writing. You get a written scope (membrane, thickness, flashings, drainage corrections, warranty tier) with the range tied to what's actually up there. No flat magic number, no vague "we'll see."
3. We install and back it. The install crew we deploy and supervise builds to manufacturer specification, our project manager inspects the work, we register your warranty, and we walk the finished roof with you or your facility manager before final payment.

That discipline comes from how ARP is built. 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 single-ply replacement, that's the difference between a number pulled from a rate sheet and a number built from your roof.

If your project is heading toward a full replacement, the commercial roof replacement guide walks the whole scope, and if your roof still has life left, a restoration coating can run $5.00 to $10.00 per square foot instead of a full replacement.

Cost content only helps you if it's honest about who we serve well, and who should call someone else.

You're probably the right fit if:

• You want the scope, membrane spec, and warranty tier in writing before anyone touches your roof
• You manage a building in Texas and want photo documentation you can hand to ownership
• You want one contractor for the assessment, the replacement, and the maintenance that follows
• You're holding the asset long-term and want the roof priced for the hold, not just the sale
• You'd rather compare scopes than chase the lowest number

You're probably not the right fit if:

• You need the single lowest bid in the market, which is a fair call, but it's not the number we'll be
• You need work to start within 24 hours with no assessment or documentation
• Your roof is under 1,000 square feet, where minimum scope makes the economics work against you
• You've been quoted a price that doesn't allow the roof to be installed correctly
