About
Alon Roofing Systems, LLC is a family owned San Antonio roofing and exterior contractor operating at alonroofing.com. Its BBB profile gives an incorporation date of January 6, 2016, names Tomas Villarreal as managing member and Belinda A. Villarreal as administrator, records BBB accreditation since September 8, 2017 with an A+ rating, and lists Alon General Construction and Alon Roofing and Solar, LLC as alternate names. The company publishes (210) 468-7663, spelled (210) GOT-ROOF, and (210) 570-2300, and the number on the City of San Antonio register, (210) 722-1808, also appears on the company's Nextdoor page.
The service list is broad for a roofer: residential and commercial roofing, replacement, repair and maintenance, plus siding, windows, gutters, insulation, doors, interior and exterior painting, and solar installed together with a new roof. The company markets free inspections and free insurance claim assistance for hail and wind damaged roofs, and states discounts for military, medical staff, firefighters, law enforcement and educators. Its own site names Owens Corning Preferred Contractor status and HUB certification, and the profile in GAF's contractor directory shows GAF Certified status with authority to offer GAF's System Plus Limited Warranty. Published service areas are San Antonio, Universal City, Converse, Schertz, Cibolo and Selma.
Bexar County is inland, so windstorm certification is not part of the picture. Hail drives most claims in this market, and the everyday wear comes from heat and ultraviolet exposure that age shingles, harden pipe boots and dry out flashing sealant. Homeowners weighing a manufacturer certified installer should check what the certification actually buys, which is usually access to an extended system warranty that a non certified contractor cannot offer.

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.

RegionSan Antonio
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
Does Texas issue a state roofing license?
No. Texas has no state roofing license, so no San Antonio roofer can be state licensed for roofing. The meaningful checks are current general liability and workers compensation insurance, City of San Antonio contractor registration, BBB standing, and voluntary credentials such as RCAT membership or a manufacturer certification you can look up in the manufacturer's own directory.
Is Alon Roofing Systems an RCAT member?
No RCAT record was found for this company when the Roofing Contractors Association of Texas member directory was searched. RCAT membership is voluntary and most companies on the City of San Antonio register are not members, so this is expected. The company's verifiable third party credentials here are its GAF certification and its BBB accreditation.
What is the difference between an RCAT Member and an RCAT Licensed Roofing Contractor?
Member means the company pays association dues. The Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned separately through RCAT's testing and continuing education program. The two are not interchangeable, and a company can be one without being the other, so ask which is being claimed.
What does GAF Certified actually get me?
GAF Certified is the entry tier of GAF's contractor program, above uncertified and below Master Elite. Its practical value is warranty access: a GAF Certified contractor can register the System Plus Limited Warranty on a qualifying GAF roof system, which extends coverage beyond the standard shingle only warranty. Ask for the warranty to be registered in writing after the job.
Is windstorm or WPI-8 certification needed in San Antonio?
No. WPI-8 windstorm certification applies to the 14 first tier Gulf Coast counties inside the Texas Windstorm Insurance Association program. Bexar County is inland and outside it, so windstorm paperwork is not part of a San Antonio roof replacement.
What actually damages roofs in San Antonio?
Hail, mainly in spring and early summer, is the leading cause of sudden loss and the usual reason for an insurance funded replacement. The slower damage comes from heat and ultraviolet exposure over long summers, which strips granules from asphalt shingles, embrittles pipe boot rubber and dries out sealant at flashings, where most leaks start.
Should I choose impact resistant Class 4 shingles?
It is usually worth pricing in a hail exposed market. Class 4 is the highest UL 2218 impact rating and stands up to hail far better than a standard shingle. Many Texas insurers give a premium credit for a Class 4 roof, so ask your carrier for the annual figure in dollars and compare it to the upgrade cost over the years you expect to stay.
Do I need a permit to replace a roof in San Antonio?
Texas has no statewide building code, so permitting is city by city. In San Antonio, roofing work runs through the city's Development Services department, and residential roofing contractors are expected to be on the city's contractor register. Get it in writing which party pulls the permit and schedules any inspection.
How should I handle the insurance side of a hail claim?
Document the damage with dated photographs, report it to your carrier promptly because Texas policies carry claim deadlines, and get an independent inspection so you understand the scope before the adjuster's visit. A contractor offering to help with the claim is normal. A contractor offering to waive or absorb your deductible is offering something illegal in Texas.
What should I confirm before signing with any roofer here?
A certificate of insurance sent to you by the insurer showing current general liability and workers compensation. A written scope covering tear off, decking, underlayment, ventilation and flashing. Both warranties named separately, the manufacturer's material or system warranty and the contractor's workmanship warranty with its length. And a check of any claimed certification directly in the manufacturer's own directory.
