TL;DR: Texas has no statewide roofing license, so anyone can call themselves a roofer — which matters a lot in San Antonio, a city that averages multiple hail events every year. This guide walks you through the credentials, questions, and red flags that separate a contractor worth hiring from one you’ll regret.
San Antonio gets hit hard by the weather. Hail season runs from roughly March through June, with the worst storms typically striking in April and May. Those aren’t small events — Texas consistently ranks as the top state for hail-related property insurance claims in the country, and Bexar County alone has lived through at least 16 major hail events over the past decade.
After every significant storm, the phones start ringing — and not just from local contractors. Storm chasers and out-of-town operators descend on neighborhoods, knock on doors, and promise fast fixes. Some are legitimate. Many are not. Knowing how to tell the difference before you sign anything can save you thousands of dollars and a serious headache.
Why Choosing a Roofer in Texas Is Harder Than in Most States
Here’s the part most homeowners don’t know: Texas has no statewide roofing contractor license. The Texas Department of Licensing and Regulation (TDLR) does not regulate roofers at the state level, meaning there is no mandatory state exam or registration required to operate a roofing business in Texas.
That regulatory gap places the burden squarely on you, the homeowner, to vet whoever you’re about to put on your roof.
There is one meaningful exception: San Antonio requires a Home Improvement Contractor (HIC) registration for roofing work, which includes proof of insurance, an FBI background check, and a registration fee. That’s a useful local filter — but it’s still not a skills test, and it doesn’t cover out-of-state operators who skip the registration entirely.
The voluntary credential worth asking about is an RCAT license — issued by the Roofing Contractors Association of Texas. To earn it, a contractor must have been operating in Texas for at least three years, carry proper insurance, pass a business-and-safety exam plus a roofing trade exam with a score of 70% or higher, and maintain good standing with the Better Business Bureau. It’s voluntary, not required — but a contractor who has it has cleared a meaningful bar.
The San Antonio Climate Reality: What Your Roof Is Up Against
Understanding the local weather environment helps you ask smarter questions. San Antonio sits at a meteorological crossroads where warm, humid Gulf air regularly collides with drier western air — conditions that are ideal for generating powerful hailstorms. Hail can range from pea-sized to softball-sized, and the damage it causes isn’t always obvious from the ground.
What makes this particularly tricky is cumulative damage. A roof may be struck multiple times in a single season, with each event adding wear that gradually weakens the whole system — often without any single event being dramatic enough to prompt an immediate claim.
Beyond hail, San Antonio’s intense summer heat and UV exposure put thermal stress on roofing materials year-round. A contractor who only knows coastal or North Texas conditions may not fully understand how that combination — repeated hail impacts followed by extreme heat cycles — accelerates shingle deterioration in the Hill Country and Bexar County corridor.
Your Vetting Checklist: 7 Things to Confirm Before You Sign
1. Verify a Local, Permanent Business Presence
Ask for a physical address — not a P.O. box — and look it up. The National Roofing Contractors Association (NRCA) advises homeowners to check for a permanent place of business, a working phone number, and a tax ID before engaging any contractor. A company that has been operating in San Antonio or South Texas for years has a reputation on the line. A storm chaser does not.
2. Demand Certificates of Insurance — Not Promises
Ask every contractor to provide an actual certificate of insurance (COI) before anyone sets foot on your roof. The certificate should show current policy dates, your job site address, general liability coverage, and — critically — workers’ compensation. If a worker is injured on your property and the contractor carries no workers’ comp, you could be held liable. This is not a formality you can skip.
3. Confirm They’ll Pull the Permit
San Antonio’s HIC registration system means legitimate contractors are registered and permitted through the city. A contractor who refuses to pull permits is signaling either that they don’t qualify or that they don’t want a record of accountability attached to the job. Either way, that’s your exit cue.
4. Check Reviews — and Read the Negative Ones
Google reviews tell a useful story, but pay attention to how a company responds to criticism, not just the star count. The NRCA also recommends contacting the Better Business Bureau (BBB) to check whether complaints have been filed. A BBB-accredited company has agreed to meet standards of transparency and responsiveness.
5. Ask About Manufacturer Certifications
Some roofing manufacturers — including GAF, Owens Corning, and CertainTeed — offer contractor certification programs that require ongoing training and quality standards. These certifications matter because they can unlock extended warranty coverage for homeowners that is not available through non-certified contractors. Ask whether the contractor is certified by the manufacturer whose materials they’re proposing to use.
6. Get Everything in Writing Before You Sign
A written proposal should include a line-item scope of work, the specific materials (brand, product line, color, weight), start and estimated completion dates, payment schedule, and warranty terms — both for materials and for the contractor’s own workmanship. If a contractor will not put the full scope in writing before you sign, that tells you what you need to know.
Industry associations including the NRCA specifically advise homeowners to insist on a written proposal covering complete descriptions of the work, specifications, approximate start and completion dates, and payment procedures.
7. Understand the Two Types of Warranty
There is a meaningful difference between a manufacturer’s material warranty (covering defective shingles or membrane sheets) and a contractor’s workmanship warranty (covering installation errors). Most early roof failures are caused by poor installation, not defective materials — so the workmanship warranty is often the more important of the two. Ask specifically: How long does the workmanship warranty last? Who backs it? What voids it?
Red Flags That Should Stop You Cold
- Door-to-door solicitation right after a storm. Legitimate local contractors don’t need to canvas neighborhoods. Storm chasers do.
- Pressure to sign the same day. A trustworthy contractor gives you time to compare and decide. If someone is pushing you to sign immediately, walk away.
- Offers to ‘cover your deductible.’ Under Texas law, a contractor offering to waive, absorb, or pay your insurance deductible is committing insurance fraud. This is not a perk — it’s a crime.
- No physical address or local references. If you can’t drive to their office and call three past customers who live within an hour of San Antonio, keep looking.
- Vague or verbal-only bids. If they won’t put it in writing before you commit, they won’t stand behind it after the job is done either.
- A deposit demand above one-third of the total job cost. Large upfront payments before any work begins are a classic storm-chaser pattern.
Insurance Claims: What a Good Contractor Does (and Doesn’t Do)
If hail damage triggers an insurance claim, the process moves fast and the documentation requirements are real. Texas insurance claims are time-sensitive — delaying a professional assessment can result in difficulty proving cause of damage or a reduced payout.
A contractor worth hiring will help you understand the claims process, document damage thoroughly, and communicate directly with your adjuster. What they will not do is ask you to sign over your claim through an Assignment of Benefits (AOB) arrangement — a practice that removes you from the process entirely and has led to widespread disputes in other storm-prone states.
If your claim touches roofing, siding, windows, or exterior painting, a single contractor who handles all of it is far easier to work with than coordinating four separate trades. That’s the practical advantage of a full-service exterior contractor — one point of contact, one warranty conversation, one schedule to track.
Why Material Knowledge Matters in San Antonio Specifically
Not every roofing material performs the same in Bexar County’s climate. A contractor who is fluent in the full range of options — asphalt shingle, metal, clay tile, concrete tile, and flat or TPO systems — can make an honest recommendation based on your home’s structure, your budget, and how long you plan to stay. One who only installs one type of material may steer you toward what they know how to install, not what’s best for your situation.
For commercial property owners and landlords with flat roofs, the material conversation is particularly important. TPO (Thermoplastic Polyolefin) is a single-ply membrane widely used on low-slope commercial roofs for its heat-reflective properties and UV resistance — both meaningful advantages in San Antonio summers. Make sure your contractor has documented experience with the specific system they’re proposing, not just asphalt shingle residential work.
The same principle applies to exteriors beyond the roof. If you’re also replacing siding or repairing a deck after storm damage, the same vetting questions apply. You can see what that process looks like for siding specifically in our guide to hiring a siding contractor on the Gulf Coast — the core checklist translates directly to San Antonio.
What to Ask on the Phone Before You Schedule a Quote
- How long have you been operating in San Antonio or Bexar County?
- Are you registered with the City of San Antonio as a Home Improvement Contractor?
- Can you send me a certificate of insurance before our appointment?
- Do you carry a voluntary RCAT license?
- Who will be on-site supervising my job — an employee or a subcontractor?
- Do you provide a separate workmanship warranty in addition to the manufacturer’s material warranty?
- Have you worked with my insurance company before, or handled similar storm damage claims?
A contractor who answers these questions directly and without hesitation is worth scheduling. One who deflects, rushes you, or can’t answer is telling you something.
