Commercial Roofing Cost in Dallas, TX (2026 Guide)
North Texas roofs take hail, high wind, long stretches of heat and sudden heavy rain, so a commercial roof replacement here is usually about more than age. The biggest swing in price is what is underneath: a dry, sound roof can often be recovered, while wet insulation or a damaged deck means tearing off to the deck. For contractor licensing, insurance claims and what to ask, see our page on commercial roofing contractors.
The ranges below come straight from our Texas cost estimator for the Dallas metro, so they match what you will see if you run your own numbers. Its three tiers are by roof system: Basic is a single-ply recover, Standard is a full tear-off and single-ply replacement, and Premium is standing-seam metal. They are typical planning estimates, not quotes.
Commercial roof replacement cost per square foot in Dallas
Single-ply recover (TPO / EPDM) over a sound deck
Full tear-off and single-ply replacement
Standing-seam metal roof
Per-sq-ft ranges at a typical 20,000 sq ft roof. Large, simple roofs spread mobilization and equipment costs and trend slightly lower per sq ft; small roofs with many penetrations trend higher (the estimator adjusts by up to ±8%).
What a 10,000 or 25,000 sq ft commercial roof costs in Dallas
| Finish level | 10,000 sq ft | 25,000 sq ft |
|---|---|---|
| Basic | $52K–$83K$5.20–$8.32/sq ft | $120K–$200K$4.94–$7.90/sq ft |
| Standard | $73K–$120K$7.28–$12/sq ft | $170K–$300K$6.91–$12/sq ft |
| Premium | $100K–$210K$10–$21/sq ft | $250K–$490K$9.87–$20/sq ft |
Totals use the estimator’s formula for Dallas and are rounded to two significant figures. Basic = single-ply recover, Standard = tear-off and single-ply replacement, Premium = standing-seam metal. Excludes structural deck replacement, rooftop HVAC work, new drains or scuppers beyond normal flashing, and insurance-claim supplements.

| Basic | 1–3 wks | 1–3 wks | 2–6 wks |
| Standard | 1–3 wks | 2–5 wks | 3–8 wks |
| Premium | 1–3 wks | 3–8 wks | 4–11 wks |
Typical ranges from our estimator. Construction weeks start after permits are issued; incomplete drawings, resubmittals and long-lead equipment are the usual causes of delay.
What drives commercial roof replacement costs in Dallas
Recover vs. tear-off
If the existing roof is dry and the deck is sound, a recover over it avoids most demolition and disposal and keeps you near $5–$8/sq ft. Building codes limit how many roof layers you can have, and wet insulation has to come out, which pushes a job into the $7–$12/sq ft range.
Insulation & energy code
When a low-slope roof with insulation above the deck is replaced, the energy code can require bringing that insulation up to current levels. Tapered insulation to fix ponding adds more. Insulation is often a bigger cost line than the membrane itself.
Membrane & system type
TPO, PVC, EPDM and modified bitumen are priced differently, and membrane thickness, attachment method (mechanically fastened, adhered or ballasted) and wind-uplift requirements all move the number. Standing-seam metal sits at the top of the range.
Hail & wind resistance
Impact-rated assemblies, thicker membranes or cover boards add cost but hold up better in hail. Some insurers recognize impact-rated roofs — ask your carrier before choosing a system.
Penetrations & rooftop equipment
Every curb, vent, skylight and pipe needs flashing. Rooftop units may have to be disconnected and raised or reset by a licensed HVAC contractor, often with a crane — ask whether bids include that work.
Warranty level
Manufacturer no-dollar-limit (NDL) warranties require approved installers, specific details and inspections, and longer warranty terms usually mean a thicker or upgraded system. Compare bids at the same warranty level.
Dallas permits and rules for commercial roofing
A commercial reroof in Dallas is usually simpler to permit than a buildout, but a few rules affect cost and who you hire.
Building permit
Commercial roof replacement generally needs a building permit from City of Dallas Development Services; minor repairs may not. Your roofing contractor should pull the permit and schedule inspections — confirm the requirement for your scope with the City.
Energy code
Dallas enforces the 2021 International Energy Conservation Code with local amendments. Roof replacements on buildings with insulation above the deck can trigger current insulation requirements, and low-slope roofs in this climate zone may have reflectance requirements — your bidders should state how they comply.

No state roofing license
Texas has no statewide license for roofing contractors. The Roofing Contractors Association of Texas (RCAT) offers a voluntary license, including a commercial category, and roof manufacturers certify the installers allowed to issue their warranties. That makes insurance, references and manufacturer certification the things to verify.
Insurance deductibles
Under Texas law, a contractor may not advertise or promise to pay, waive or rebate an insured’s deductible on a property insurance claim. Treat any bid that offers to “cover your deductible” as a red flag, and make sure the bid’s scope matches what your insurer approved.

Rooftop HVAC
Disconnecting, raising and resetting rooftop units is HVAC work that requires a contractor licensed by TDLR. On a reroof it is usually subcontracted by the roofer or hired separately — make sure it is in someone’s scope.

How to keep your Dallas commercial roof replacement on budget
- Get a roof survey before pricing. Core cuts or a moisture scan show whether the insulation is dry enough to recover — the single biggest cost decision.
- Fix drainage while the roof is open. Tapered insulation, crickets and added drains cost less now than repeated leak repairs later.
- Bundle rooftop unit replacements with the reroof so units are lifted once, not twice.
- Schedule outside the spring hail season when you can; crews are easier to book and weather delays are fewer.
- Compare warranty terms, not just price. A 20-year NDL warranty and a 10-year material-only warranty are not the same roof.
How to get accurate bids
- Give every bidder the same scope: roof area, recover or tear-off, membrane type and thickness, insulation R-value, attachment method and warranty term.
- Ask for line items for tear-off and disposal, insulation and cover board, membrane, flashing and penetrations, sheet metal, rooftop equipment work and permits.
- Ask how deck repairs are priced — a unit price per sheet or square foot keeps surprises predictable.
- Check insurance, references and manufacturer certification with our commercial contractor vetting checklist, and use our commercial construction bid checklist to build the request.
- Collect at least three bids and compare them line by line — see our guide to comparing contractor bids.

How much does a commercial roof cost per square foot in Dallas?
Typical planning estimates for Dallas–Fort Worth are about $5–$8 per sq ft for a single-ply recover over a sound roof, $7–$12 per sq ft for a full tear-off and single-ply replacement, and $10–$20 per sq ft for standing-seam metal. These are planning ranges, not quotes.
How much does it cost to replace a 25,000 sq ft commercial roof?
In Dallas, roughly $120K–$200K for a recover, $170K–$300K for a tear-off and single-ply replacement, and $250K–$490K for standing-seam metal. For 10,000 sq ft, about $52K–$83K, $73K–$120K and $100K–$210K. Deck repairs, rooftop HVAC work and new drains are extra.
Can I put a new roof over my existing commercial roof?
Sometimes. A recover is possible when the existing roof and insulation are dry, the deck is sound and the building code’s limit on roof layers isn’t exceeded. A moisture survey or core cuts tell you. Wet insulation traps moisture under the new membrane and has to be removed.
Do I need a permit to replace a commercial roof in Dallas?
Commercial roof replacement generally requires a building permit from the City of Dallas, and minor repairs may not. Your roofing contractor should pull the permit and arrange inspections; confirm the requirement for your scope with the City.
Can a roofer pay my insurance deductible?
No. Texas law makes it an offense for a contractor to advertise or promise to pay, waive or rebate a property insurance deductible. Any bid that offers to do so is a red flag.
How long does a commercial roof replacement take?
For a 20,000 sq ft building, plan on about 1–3 weeks for the permit, then roughly 1–3 weeks for a recover, 2–5 weeks for a tear-off and replacement, or 3–8 weeks for metal, plus weather days. Material lead times and crane scheduling for rooftop units are the usual causes of delay.
