Why ARP
When your flat roof starts leaking, the fear isn't the water — it's explaining to ownership why the building flooded on your watch. That's the call ARP's commercial roofing in San Antonio team answers most. A San Antonio commercial roof takes a specific beating: water that ponds for days after a storm, and spring supercells that lift seams and pull flashings loose at every rooftop unit.
As a GAF GoldElite Commercial Contractor, ARP repairs single-ply, coating, and flashing systems and documents each one, so the number you approve is the number you pay.
What sets an ARP repair apart:
When we take on a flat-roof repair on a multi-tenant building downtown or off Loop 410, the first thing I map out isn't the leak. It's your tenants' hours. We stage the seam and flashing work around the businesses under that roof, so the fix protects your building without ever shutting its doors.

How It Works
Here's the order that protects you — and your tenants.
Assessment and leak trace. An ARP project manager walks the roof, reads the drains, seams, and flashings, and traces the leak to the point that actually failed — not just the spot over your stain.
Written scope and job total. You get the repair scope in writing with a flat price before anyone touches the roof. When the work needs a permit, ARP files it through the City of San Antonio Development Services Department at 1901 S. Alamo Street.
Documented repair and warranty. The crew ARP deploys completes the fix under project-manager supervision, with before-and-after photos and the manufacturer warranty registered where the system qualifies.

SA Cost Drivers
A San Antonio roof repair is priced by the job, not by the square foot. Most commercial roof repairs in San Antonio are flat-priced work: a single leak, open seam, or failed rooftop flashing typically runs $1,500 to $3,500; a larger section cut-and-replace is quoted by area, and emergency storm response runs higher. You approve a flat job total before work starts — final price depends on existing roof condition, drainage, and access.
What moves your number is local. A San Antonio flat roof bakes under summer heat and UV that craze a membrane year after year, while water that ponds for days after a storm works every weak seam and drain. Spring is the other driver: Bexar County's supercell season peaks in March, and hail and straight-line wind lift flashings loose at HVAC curbs and parapets. Roof access — building height, ponding, whether a lift is required — and any City of San Antonio permit timeline round out what a flat roof repair in San Antonio actually costs.
Vetting a Local Roofer
Type "roofer San Antonio," "commercial roofer San Antonio," or "commercial roofers San Antonio" into a search bar and the same wall of names comes back — they look alike until you check who documents the work. Plenty of roofers in San Antonio can run a tube of sealant over a stain. Fewer commercial roofers in San Antonio will trace the leak, document the repair, and stand behind it — and telling them apart is your real job. Before you hire a commercial roofer in San Antonio, confirm the basics:
Be wary of the storm-chaser pattern that follows every spring hail season into Bexar County — out-of-town plates, no local address, a door-knock, and pressure to sign before the water's even dry. A settled San Antonio roofer doesn't work that way.

Get your San Antonio repair assessment
A repair is priced by the job — the leak, seam, or flashing we actually fix — not by your roof's square footage. Here's the honest range, and the fastest way to get a firm number in writing.
Typical repair — flat-priced
$1,500 – $3,500 per job
Most commercial roof repairs — a single leak, open seam, or failed rooftop flashing — are flat-priced. A larger section cut-and-replace is quoted by area, and emergency storm response runs higher. You approve a flat job total before work starts.
Why it's flat, not per square foot
Anyone quoting a firm repair price over the phone is guessing. We trace the leak to its real failure point, then put the scope and a flat price in writing after a free on-roof assessment.
Free and photo-documented — a written scope and flat price before anyone touches the roof.
Request in — we'll text to confirm

Honest fit check
The best way to judge any San Antonio 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
No — we'll say so up front
We'd rather tell you that on the phone than waste a walkthrough.
No cost, no obligation
A free San Antonio commercial roof assessment costs nothing and comes with no obligation. Instead of a phone guess, a project manager finds the actual source of the leak on the roof, photographs it, and gives you a written scope for the fix.
Most flat-roof leaks trace back to a failed seam, an open flashing, or a rooftop penetration — not the spot where water shows up inside. We find the real source before we quote.
You get the photo set and a flat job total in writing before any work starts, and on commercial projects the scope is COO-reviewed.
From assessment to warranty
We measure your roof, photograph it, and document what's actually there — not a curbside guess. You get the photo set whether you hire us or not.
You'll see line-item scope, materials, warranty options, and a real number in writing. On commercial projects that document is COO-reviewed. Nothing starts until you've read it.
A crew led by an ARP project manager does the work, pulls the San Antonio permit, and inspects at the key stages — then your manufacturer warranty registers in your name within 30 days.
No fee, no deposit, no pressure. We confirm your address is covered before we schedule — then a project manager walks the roof.
