A new roof is one of the biggest investments you will make in your home, and in San Antonio you are choosing a contractor in a crowded market right after every hail season fills the neighborhood with out-of-town crews. The good news is that a good contractor is not hard to spot once you know what to look at. Verify insurance before anything else, confirm a real local track record, get every detail in writing, and be careful with anyone who showed up at your door the week after a storm. This guide walks through each of those, in plain language, so you can hire with confidence instead of guessing.
Do roofing contractors have to be licensed in Texas?
Here is the part most homeowners do not know: Texas does not license roofing contractors at the state level. There is no state roofing license to check, which means “licensed” is a weaker filter here than it is in a lot of other states. Some cities and counties have their own permit and registration rules, but the state itself does not issue a roofing license.
That does not mean anything goes. It means you have to verify the things that actually protect you: proof of insurance, manufacturer certifications, a verifiable local track record, and a written contract. The rest of this guide is built around exactly those signals, because in Texas they matter more than a license number ever could.
Verify insurance before anything else
Insurance is the one item you should confirm before you even discuss the roof. A reputable San Antonio roofer carries two kinds:
- General liability, which covers damage to your property during the work.
- Workers’ compensation, which covers the crew if someone is injured on your roof. Without it, an injury on your property can become your problem.
Ask for a certificate of insurance, and do not stop there. Call the insurance carrier listed on it and confirm the policy is active. It takes five minutes and it is the single best way to filter out the operators you do not want on a ladder over your home.
Look for manufacturer certifications
Because Texas has no state license, manufacturer certifications do a lot of the work of proving a contractor is properly trained. Shingle and roofing manufacturers such as GAF, CertainTeed, and Owens Corning certify contractors who meet their standards, and certified installers can often offer stronger, longer manufacturer warranties than a non-certified crew can.
Certification also tells you the manufacturer has vetted the company’s work and standing. When you are comparing two bids that look similar on paper, the one from a certified installer with a documented specialty is usually the safer choice. A contractor who has earned a master certification in shingle application, for example, has demonstrated a level of skill that a general crew has not.
Choose a local, established San Antonio contractor
A contractor with a real physical address in the San Antonio area and years of history here is accountable in a way a traveling crew is not. Local roofers know how our heat cycles age a roof, how the spring hail seasons behave, and what the permitting looks like in the different jurisdictions around the metro. If a warranty issue comes up in three years, a local company is still here to answer the phone.
Look for a business that has been serving the area for at least several years, has a findable address, and can point you to recent local work. Longevity is not a vanity metric on a roof. It is a sign the company will still exist when you need it.
Watch for storm chasers after San Antonio hail storms
After a big hail storm, out-of-town crews flood San Antonio neighborhoods knocking on doors. The pitch is familiar: they are “already working in your neighborhood,” they can start tomorrow, and they will handle everything. Some of them do fine work. Many do not, and by the time a problem surfaces they have moved on to the next city and cannot be reached.
The warning signs are consistent. High pressure to sign today. An out-of-state phone number or truck. A quote written on the spot with no real inspection. An offer to “waive your deductible,” which is not something a legitimate contractor does. If a roof took real storm damage, you are better off calling a local company for a proper look and, when insurance is involved, letting someone local help you work through the claim with your insurer rather than handing it to a stranger. When a Texas hail storm hits, a local storm-damage repair team is the safer first call.
Get a detailed, itemized estimate, and get more than one
A trustworthy estimate is specific. It lists the work line by line: tear-off and disposal of the old roof, the material brand and color, flashing, ventilation, underlayment, labor, and cleanup. A one-line number with no breakdown makes it impossible to compare bids or to know what you are actually paying for.
Get two or three estimates and compare the scope, not just the bottom line. The cheapest bid often wins by leaving something out, and the gap shows up later as an inferior material, a skipped step, or a warranty claim that gets denied. Start with an honest look at the roof itself. A no-cost inspection of your actual roof gives you a real baseline to measure every quote against.
Understand the two warranties
Every good roof comes with two separate warranties, and homeowners mix them up constantly:
- The manufacturer warranty covers the materials, the shingles or metal panels themselves, if they fail prematurely.
- The workmanship warranty covers the labor, the installation itself, if something was done wrong.
A great shingle installed badly still leaks, and a manufacturer warranty will not cover a bad install. Ask about both, get the terms in writing, and confirm the length of each. Certified contractors can often back their materials with enhanced manufacturer coverage, which is one more reason certification matters.
Insist on a written contract
Never run a roofing project on a handshake. A proper contract spells out the start and completion dates, the payment schedule, the exact materials by brand and type and color, who handles cleanup and permits, and whether any of the work will be subcontracted. It protects both sides and it forces clarity before the first shingle comes off.
Be cautious with payment terms. No reputable roofer asks for the full amount up front. A modest deposit with the balance due on completion is normal. Cash-only demands and requests for full prepayment are two of the clearest signs to keep looking.
Repair or replacement? A good contractor tells you the truth
One of the fastest ways to judge a contractor is whether they are honest about what your roof actually needs. Not every roof with a problem needs to be replaced. A trustworthy roofer will tell you when a targeted roof repair is the right call and when replacement genuinely makes more sense, and they will show you why. If every conversation ends at “you need a full replacement” without a clear reason, get another opinion. We wrote a plain-English breakdown of whether a repair or a full replacement makes sense if you want to think it through before anyone comes out.
Questions to ask before you hire
Bring this list to every estimate. The answers tell you almost everything:
- Are you licensed where required, and can you show current general liability and workers’ compensation insurance?
- Are you certified by any roofing manufacturers, and what warranty does that certification let you offer?
- How long have you been roofing in the San Antonio area, and do you have a local address?
- Can you provide references from recent local jobs?
- Will you provide a written, itemized estimate?
- Who will actually be on my roof, your crew or subcontractors?
- What is your payment schedule?
- What does your workmanship warranty cover, and for how long?
- Will you pull the required permits?
- How do you handle unexpected issues found once the old roof is off?
Any contractor worth hiring will answer these easily. Hesitation or vague answers are information too.
Red flags that mean walk away
A quick recap of the signals that should end the conversation:
- No proof of insurance, or a certificate they will not let you verify
- Demands full payment up front, or cash only
- Pressures you to sign the same day
- No local physical address
- Offers to waive or absorb your insurance deductible
- Refuses to put the scope and price in writing
- Skips permits to save time
None of these are small. Any one of them is a good reason to call someone else.

Frequently asked questions
How can you tell a good roofer?
A good roofer carries verifiable general liability and workers’ compensation insurance, has a real local address and years of history in the area, holds manufacturer certifications, provides a written itemized estimate, and gives you honest guidance on repair versus replacement instead of pushing the most expensive option.
Do roofers need a license in Texas?
No. Texas does not issue a state roofing license. Some local jurisdictions have their own permit or registration requirements, but at the state level there is no license to check. That is why insurance, manufacturer certifications, and a verifiable local track record matter so much here.
What is the 25% rule for roofing?
The 25 percent rule refers to a building-code guideline stating that if more than a quarter of a roof is damaged within a 12-month period, the whole roof section generally must be brought up to current code rather than patched. A reputable local contractor can tell you whether it applies to your situation after a proper inspection.
How many roofing estimates should I get?
Two to three is a good target. More than that rarely adds information and can slow down an urgent repair. Focus on comparing the scope of each itemized estimate, not just the final number.
How do I know if a roofer is overcharging me?
Compare itemized estimates from more than one local contractor and look at what each one includes rather than the total alone. A quote with no line-item breakdown, or one that is dramatically lower than the others, is usually the one to question.
