About
Mighty Fortress Roofing is a San Antonio residential and light commercial roofer. Its own pages describe it as based in North San Antonio and give a business address of 7550 Interstate 10 Frontage Road, Suite 1440, San Antonio, TX 78229. The City of San Antonio home improvement contractor registration is in the 2025 issue series and the company's website and social presence are similarly recent, so there is not yet much independent track record to weigh.
The company sets out a simple three step process on its own site: a free inspection with a written report, then a plan covering scope and finances, then the work with cleanup and communication handled. It states that it works directly with insurance agents on storm and hail claims to maximise coverage and reduce out of pocket cost, offers 0 percent interest financing with low down payments, and backs projects with its own warranty. Listed services are roof repair and replacement, storm damage and emergency response, roof inspection and maintenance, shingle, tile and flat roof repairs, roof leaks, and chimney, soffit and fascia work.
Two things to check before you sign. The company publishes (210) 716-0529 as its contact number, while the number on the city registration is (210) 273-0991, which we could not find on any of its own pages. And no manufacturer certification is claimed on the site or found on any manufacturer contractor directory, so ask directly which manufacturer warranty the company is able to register on your roof.
Highlights
Free inspection with a written report before any plan or price is put forward
Works directly with insurance agents on storm and hail claims, which matters in a hail-exposed market
0 percent interest financing with low down payments offered on its own site
Backs its work with its own workmanship warranty
Holds a current City of San Antonio home improvement contractor registration
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.
The company describes itself as a licensed San Antonio roofing company. Read that carefully, because Texas does not issue a state roofing licence. What a Texas roofer can hold is city or county registration where required, insurance, and voluntary industry credentials. In this case the relevant item is the City of San Antonio home improvement contractor registration, number SA-LIC-HIC-LIC25-16901026. Nobody in Texas roofing holds a state licence.
Is the company an RCAT member?
We searched the Roofing Contractors Association of Texas member directory ourselves on the keywords Mighty Fortress and Fortress, and no record came back. That means not found via RCAT search, not that anything is wrong. RCAT membership is voluntary, and RCAT also runs a separate, harder to earn Licensed Roofing Contractor credential that is not the same thing as plain membership.
Which phone number should I use?
Use the number the company publishes on its own site and Nextdoor page, (210) 716-0529. The city registration lists (210) 273-0991, which does not appear on any page the company controls that we could find. Both may be real lines for the same business, but only one is verifiable, so start with the published one and ask them to confirm the registration number.
Is 7550 Interstate 10 Frontage Road a real office?
It is the address the company publishes for itself, in a multi-tenant office building on the IH-10 frontage in the Medical Center area, with a high suite number. A suite in a shared building is normal for a roofing company that runs crews out of trucks rather than a yard, so it is not a red flag by itself. If it matters to you, ask to meet there or ask where their materials and equipment are actually stored.
How new is this company?
Newer than most on this list. Its City of San Antonio registration is in the 2025 series and its website and social profiles are recent. That is not a reason to rule a contractor out, but it does mean you should lean harder on the things you can check now: current insurance certificates sent by the insurer, references from jobs finished in the last twelve months, and clear written warranty terms.
Does the company hold GAF, Owens Corning or CertainTeed certification?
We found none, and the company claims none on its site. That matters because the enhanced manufacturer warranties, the ones that cover labour as well as material for decades, are only available through contractors enrolled in those programmes. Ask which manufacturer programmes the company is in and what warranty it can actually register, then verify it on the manufacturer's own contractor locator before you sign.
How should I handle a hail claim in San Antonio?
Document first. Photograph the roof, gutters, screens and any dented soft metal after the storm, note the date, and get an independent inspection before an adjuster visits. Hail bruising on shingles is genuinely hard to see from the ground and often does not leak until months later. Beware anyone who offers to cover your deductible, which is illegal in Texas, and read your policy for whether it pays replacement cost or actual cash value.
Are impact resistant shingles a good idea here?
Usually. A UL 2218 Class 4 shingle survives hail better than a standard architectural shingle, and most Texas insurers offer a premium credit for a Class 4 roof, which can pay back a meaningful share of the upgrade over the roof's life. Confirm the discount with your insurer first, then have the exact product name and impact rating written into the contract.
How long does a roof last in San Antonio?
Less than the number on the shingle wrapper, in most cases. Sustained heat, intense UV and repeated hail all age a roof faster here than in a milder climate, and ventilation quality makes a large difference. Plan on a shorter real world life than the warranty length, keep the attic properly ventilated, and get an inspection after every significant hailstorm rather than on a calendar.
What paperwork should I insist on before work starts?
A certificate of general liability and workers compensation insurance sent directly from the insurer or agent. A written scope naming the shingle line, underlayment, flashing, ventilation and disposal. The workmanship warranty term in writing, separate from any manufacturer warranty. A payment schedule that does not front-load most of the cost. And confirmation of who pulls the permit, which should be the contractor.
