Commercial Roof Repair in San Antonio
Most commercial leaks start small. A seam opens on a TPO membrane, flashing lifts around a rooftop unit, or a clogged drain lets water sit on the roof for days after a storm. As a local roofing company in San Antonio, we find the source, fix it, and tell you honestly whether the rest of the roof still has years left in it. Our crews use drone inspections and thermal (infrared) scans to spot problem areas quickly, including wet insulation you can’t see from the surface.
If a storm opens up your roof, call us any time, day or night. We offer 24/7 emergency service and same-day tarping to keep water out until the permanent repair is done; see our emergency roof repair page. After hail or high winds, we document the damage and work directly with your adjuster. Our San Antonio roof insurance claim help page explains how that works.
Commercial Roofing Systems We Install
Most commercial buildings in San Antonio have flat or low-slope roofs, and the right system depends on the building, how it’s used and how long you plan to own it. We install, repair and maintain all of these:
- TPO: a white, heat-welded single-ply membrane. Its reflective surface helps keep buildings cooler through long Texas summers.
- PVC: a single-ply membrane that holds up well to grease and chemicals, which makes it a common pick for restaurants.
- EPDM: a durable rubber membrane found on many older low-slope roofs around the city.
- Modified bitumen: layered asphalt sheets that stand up well to foot traffic and are easy to patch.
- Built-up roofing: layers of asphalt and felt, often called tar and gravel. We repair aging built-up roofs and replace them when repairs stop making sense.
- Metal roofing: panel and standing seam systems for commercial and industrial buildings. See our metal roofing page.
- Roof coatings: silicone and acrylic coatings that seal and restore a sound roof, often without a full tear-off.
- Spray foam (SPF): a seamless foam roof that seals and insulates in one layer.
Apex is certified by Atlas Pro, Carlisle and Firestone (now Holcim Elevate), so those systems go on the way the manufacturer intends. Want to compare systems side by side? Our commercial roofing systems page goes deeper on each one.
Commercial Roof Replacement
When a roof is past repair, we inspect it, explain your options in plain language and give you a written recommendation. If you go ahead, our team handles the whole job, from tear-off to final cleanup.
We know a roof project can’t shut your business down. We phase the work section by section and plan around your hours, deliveries and tenants, so your doors stay open while we work. Roof financing is available for commercial clients too.
What Commercial Roofing Costs in San Antonio
Commercial roof prices vary a lot with the size of the roof, the system, the number of rooftop units and drains, and whether the old roof has to come off first. As a starting point, here are typical price ranges per square foot from national cost guides published in 2026:
- EPDM: about $3 to $7 per square foot
- TPO: about $4 to $8 per square foot
- Modified bitumen: about $4 to $8 per square foot
- Built-up roofing: about $5 to $12 per square foot
- Metal: about $7 to $15 per square foot
- PVC: usually priced above TPO
- Spray foam (SPF): about $6 to $14 per square foot installed
- Silicone roof coating: about $1.50 to $4.50 per square foot installed
Sources: ServiceTitan (membrane, built-up and metal ranges), Roofing Observations (spray foam) and Angi (coatings). Thumbtack puts most full commercial replacements at $5 to $14 per square foot installed.
These are general ranges, not Apex quotes. Your real number comes after a free roof inspection, followed by a written estimate.
Built for San Antonio Weather
Commercial roofs here take three kinds of punishment. Summer heat bakes dark membranes and speeds up aging, which is why reflective white TPO and PVC are so common across the city. Spring storms bring hail and straight-line winds. The National Weather Service office for Austin/San Antonio issues the severe thunderstorm warnings for Bexar County, and those are the days our phones ring. Heavy downpours also test low-slope drainage: water still sitting on a flat roof two days after rain is a sign the drains or the slope need attention.
We serve commercial properties all over the city, from office and retail buildings along Loop 1604 and in the Medical Center area to warehouses and industrial buildings along I-35 and I-10 and around Port San Antonio.
Commercial Roof Maintenance Plans
A maintenance plan is the most affordable way to make a commercial roof last. We recommend an inspection twice a year, once in spring and once in fall, plus a check after any hail or wind event. Each visit covers:
- A full walk of the roof surface, seams, flashing and drains
- Small repairs to cracks, punctures and loose membrane before they turn into leaks
- Thermal (infrared) scans where we suspect trapped moisture
- A written report with photos to help you budget for the years ahead
Start with a free roof inspection and we’ll tell you where your roof stands today.

Frequently Asked Questions
Do you do commercial roofing in San Antonio?
Yes. Apex Roofing & General Contractors repairs, replaces and maintains commercial roofs across San Antonio and Bexar County. Our office is at 6414 W. Loop 1604 N, Suite 210, and every job starts with a free roof inspection.
What commercial roofing systems do you install?
We install and repair TPO, PVC, EPDM, modified bitumen, built-up (tar and gravel), metal, silicone and acrylic roof coatings, and spray foam. For flat roofs in San Antonio, white TPO and PVC are popular because they reflect heat. We recommend a system after we inspect your building.
Can my commercial roof be repaired instead of replaced?
Often, yes. Many leaks come from a single seam, flashing detail or drain, and a targeted repair fixes them for far less than a new roof. A roof coating can also add years to a sound roof. We’ll tell you honestly when replacement is the better investment.
Do you offer 24/7 emergency commercial roof repair?
Yes. Call (726) 727-7663 any time, day or night. We offer same-day tarping to keep water out of your building until the permanent repair is done.
Can my business stay open while you replace the roof?
Yes. We phase the work section by section and plan around your hours, deliveries and tenants, so most businesses keep operating while we work.
How often should a commercial roof be inspected in San Antonio?
At least twice a year, once in spring and once in fall, plus after any hail or high-wind storm. Our maintenance plans cover these visits, small repairs and a written photo report, with thermal (infrared) scans where we suspect trapped moisture.
Do you help with insurance claims after hail damages a commercial roof?
Yes. We inspect the roof, document the hail or wind damage with photos and a detailed report, and work directly with your insurance adjuster to make the claim process smoother.
How much does a commercial roof cost in San Antonio?
It depends on the size of the roof, the system, the rooftop units and drains, and whether the old roof has to come off. National 2026 cost guides put most full commercial replacements at about $5 to $14 per square foot installed. Your real number comes after a free inspection and a written estimate.
Is Apex certified by roofing manufacturers?
