About
Alamo Roofing is a San Antonio roofing company operating from 12075 Starcrest Dr in north-east Bexar County (78247), with a second Central Texas office at 2512 W Pecan St in Pflugerville. The BBB files it as Alamo Roofing, LLC, founded 2 February 2022, BBB Accredited since 28 May 2025 with an A+ rating, under president Alfredo Cortez, with Duke Johnson as marketing director. The register phone (210) 707-4342 is the number carried on the company's Owens Corning contractor profile and its GuildQuality profile at the Starcrest Dr address, which is how this record was matched. The company also publishes (210) 512-7663 for San Antonio and (512) 842-7000 for Austin on its own website.
The work runs both residential and commercial. On the residential side it lists roof inspection, replacement, repair, leak repair, storm damage repair and insurance claims assistance, in asphalt shingles, tile, metal and stone-coated steel. On the commercial side it lists roof inspection, replacement, repair and coatings across flat and low-slope systems including TPO, PVC and built-up roofing, and it offers thermal drone inspection, which is a genuinely useful tool for locating trapped moisture in a flat roof without cutting it open. Published hours are Monday to Friday 7.30am to 7.30pm and Saturday 8am to 4pm, closed Sunday. Stated service areas are San Antonio, Alamo Heights and Shavano Park in Bexar County, and Austin, Pflugerville, Round Rock and Cedar Park in Central Texas.
The strongest credential here is checkable at source rather than taken on trust. Owens Corning's own contractor locator lists this company, at the Starcrest Dr address and the (210) 707-4342 number, as an Owens Corning Platinum Preferred Contractor, which is the top tier of the Owens Corning network and unlocks its strongest system warranties. That profile URL is included below. Alamo Roofing also carries an independent GuildQuality survey profile showing 4.7 stars across 74 verified homeowner reviews. It is not listed in the Roofing Contractors Association of Texas member directory. Texas has no state roofing license, so alongside those credentials the checks that matter are current general liability and workers' compensation certificates sent directly by the insurance agency, and clarity on exactly which Owens Corning warranty tier is being registered on your roof.

Insurance & credential verification
Texas does not issue a state roofing license, so we verify companies the way homeowners actually can: confirming insurance coverage, checking RCAT (Roofing Contractors Association of Texas) status, and checking city or county registration where the local jurisdiction requires one. Every credential below links to the actual issuing organization's own public lookup — don't just take our checkmark for it. Always ask for a current certificate of insurance before signing any contract.

Confirm this yourself: ask the company for their certificate of insurance (COI). Note that RCAT's Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned and held by a named individual at a company, not by the business itself, which is why we name that person above where we know it; Texas issues no company roofing license at all. RCAT and NTRCA status can be checked in their own public directories (RCAT, NTRCA) — use the "Licensed"/"Accredited" filter to see more than plain membership. GAF's contractor verification tool and Owens Corning's Texas locator confirm those tiers directly; CertainTeed doesn't offer a comparable self-serve lookup, so ask to see that certificate in person. BBB accreditation and rating are on bbb.org. Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly. Corpus Christi's STAR program has its own online contractor registry — for any other city or county registration claim, confirm directly with that jurisdiction's permit office.

Frequently asked
There are several San Antonio companies with Alamo in the name. Which one is this?
This is Alamo Roofing, LLC of 12075 Starcrest Dr, San Antonio 78247, website alamoroofing.com, register phone (210) 707-4342, president Alfredo Cortez. It is a separate business from Alamo Roofing Pros, LLC, from Alamo City Home Exteriors and from Alamo Roofing & Metal Co., Inc. of 1319 March Rd, all of which are also San Antonio companies with their own registrations, reviews and credentials. Match on the phone number and the Starcrest Dr address before applying anything you read online to this company.
What does Owens Corning Platinum Preferred actually mean?
Platinum Preferred is the top tier of the Owens Corning Roofing Contractor Network, above the entry-level Preferred tier. It carries additional training, review and standards requirements and it unlocks Owens Corning's strongest system warranties, including extended workmanship coverage backed by the manufacturer. It is a manufacturer programme, not a government license, and Texas issues no state roofing license at all. You can check this company's tier yourself on the Owens Corning contractor locator profile linked on this listing.
Is Alamo Roofing an RCAT member or an RCAT Licensed Roofing Contractor?
Neither was found. A keyword search of the Roofing Contractors Association of Texas directory at web.rcat.net for 'Alamo' returns no results, and the company does not appear among the 61 records the directory returns for San Antonio. RCAT membership is voluntary and paid, so absence is not a mark against the company. In this case the Owens Corning Platinum Preferred tier and the BBB accreditation are the checkable credentials on the table.
What is the difference between an RCAT Member and an RCAT Licensed Roofing Contractor?
They are two different things. A Member pays annual dues to the association. The Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned separately through RCAT's examination and continuing education requirements. A company can be a dues-paying Member without holding the credential, so ask which one a contractor actually has rather than accepting 'RCAT' as a single claim.
Does Texas issue a state roofing license?
No. Texas has no state roofing license and no state roofing board, so no Texas roofer is state licensed for roofing. The real trust signals here are verified current insurance, city or county registration where the local jurisdiction requires it, manufacturer credentials you can look up on the manufacturer's own site, and complaint history. Alamo Roofing is registered as a home improvement contractor with the City of San Antonio.
Why should I care about thermal drone inspection on a flat roof?
On a flat or low-slope commercial roof, water often tracks a long way from the entry point and sits inside the insulation where nobody can see it. An infrared scan flown after sunset shows wet insulation as a warm patch because it releases stored heat more slowly than dry insulation, which lets the contractor map the saturated area and cut out only what needs replacing instead of guessing or tearing off the whole roof. It is a genuinely useful diagnostic rather than a gimmick.
How bad is hail in north-east Bexar County?
Bexar County sits at the southern end of the Texas hail belt and takes damaging hail most springs, usually March through June. Hail rarely punches a visible hole in an asphalt roof. It bruises the shingle mat and knocks off the protective granules, shortening the remaining life, so damage is easy to miss from the ground and often only shows up as a leak one or two seasons later. Get a roof looked at after any storm that drops stones bigger than a coin.
Are Class 4 impact-resistant shingles worth it here?
For most Bexar County homeowners, yes. Class 4 is the highest rating under the UL 2218 impact test, and many Texas insurers offer a premium credit for a Class 4 roof. Ask your own carrier what the credit is worth annually on your policy, then compare it against the upgrade cost over the roof's expected life. Ask this contractor specifically which Owens Corning impact-resistant line they would use and what warranty tier comes with it.
Do I need a permit to replace a roof in San Antonio?
Yes for most reroofing work inside city limits, handled through the City of San Antonio Development Services Department, and residential home improvement contractors are expected to be registered with the city. Texas has no statewide building code, so suburbs such as Shavano Park and Alamo Heights, and the Austin-area cities this company also serves, each set their own requirements. Confirm for your address and have the contractor pull the permit rather than you.
What should I confirm before signing with a Platinum Preferred contractor?
Ask which specific Owens Corning warranty is being registered on your roof and get the tier in writing, because Platinum Preferred status makes the strongest warranties available but does not automatically mean yours is the one being used. Get a line-item scope covering tear-off, decking replacement allowance, underlayment, drip edge, flashing, pipe boots, ventilation and haul-away. Have the insurance agency email you the general liability and workers' compensation certificates directly. Confirm the workmanship warranty length, who pulls the permit and the payment schedule. In Texas a roofing contractor cannot adjust your insurance claim on a property they are contracted to work on, and any offer to waive or absorb your deductible is illegal.
