About
David Gillian the Roofing Guy is a small, owner-operated roofing business based in Stockdale, in Wilson County, roughly 40 miles southeast of San Antonio. David Gillian is named as Owner/Operator on the Better Business Bureau record, which puts the business start date at 21 April 2022 and lists it as a BBB Accredited Business with an A+ rating since 19 March 2024. The mailing address is PO Box 462, Stockdale, TX 78160, and the physical location shown on its Yelp listing is 198 County Rd 429, Stockdale, a rural county road address that reads as a home base rather than a yard or showroom. That is a normal shape for a one-person roofing business and not a mark against it.
The trade experience is much longer than the entity. The company's own material and its Nextdoor page say Gillian is the son of a roofing contractor and has been active in the industry as an adult since 1975, across roofing manufacturing, distribution, consulting and contracting. Published services are roof renovation and replacement, roofing repairs, commercial roofing, gutter installation and repair, and exterior house painting, and its projects page describes the operation as a full service exterior restoration business that also handles stucco, windows and air conditioning damage. The work shown is a mix of houses, manufactured homes, churches and small commercial buildings, with named project locations in Stockdale, Falls City, Seguin, Marble Falls and San Antonio.
Wilson County is inland, well away from the Gulf Coast. Hail and wind are what generate insurance claims in this part of South Central Texas, and the long summer of heat and UV is what quietly ages an asphalt roof between storms. The company states a 2 million dollar general liability policy and offers free estimates, and its stated coverage is "all of South Texas" worked out of Stockdale. The city register carried no phone number for this business at all; the number published on its own contact page is (830) 340-5115 and the email is dgroofingguy@gmail.com.

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
Who actually runs this business?
David Gillian himself. The BBB record names him as Owner/Operator and the business trades under his own name. He is the son of a roofing contractor and has been active in the roofing industry since 1975, including time in roofing manufacturing, distribution and consulting as well as contracting. The BBB business start date for this entity is 21 April 2022, so the company is younger than the man's career by a long way.
The City of San Antonio register has no phone number for this company. How do I reach it?
The register field is genuinely blank, but the company publishes its own contact details. The phone number on its contact page is (830) 340-5115, the email is dgroofingguy@gmail.com, and the same 830 number appears on its BBB profile. The 830 area code covers Wilson County, which is consistent with a Stockdale base.
Does Texas license roofing contractors?
No. There is no state roofing license in Texas, so no roofer in Wilson County or San Antonio holds one, and any advertisement implying a state license is misleading. What you can actually verify is a current general liability certificate and workers compensation cover sent to you by the insurer or agent, city registration where a city requires it, and any voluntary trade or manufacturer credentials.
Is this company an RCAT member?
Not found via RCAT search. RCAT is the Roofing Contractors Association of Texas, a voluntary trade body, and it keeps plain dues-paying membership separate from the separately earned Licensed Roofing Contractor credential (CRRL, RRL or CRL). We searched the RCAT directory on Keyword=Gillian and Keyword=Roofing Guy and both returned no results, so this is a not-found result rather than a finding that the company was rejected. Most Texas roofers are not RCAT members.
Should I worry that this is essentially a one-man business?
Not by itself. A small owner-operated roofer working out of a rural home address is a real business, and you deal with the decision maker rather than a commissioned salesperson. What you should do is size the job to the outfit. For a full replacement, ask how many people will be on the roof, whether they are employees or a subcontracted crew, who supervises on the day, and how long the workmanship warranty runs and who honors it.
Stockdale is about 40 miles from San Antonio. Will they travel to my house?
The company states coverage across all of South Texas and is registered with the City of San Antonio, and its own project pages name work in Stockdale, Falls City, Seguin, Marble Falls and San Antonio. That is a wide rural footprint for a small operation, so confirm the travel is priced into the quote and ask what the response time would be for a leak callback rather than an initial estimate.
How does a hail or wind claim usually run out here?
You report the loss to your carrier, an adjuster inspects, and the carrier issues a scope and an estimate. A roofer can meet the adjuster, point out damage that was missed and supplement the claim if the scope comes back short. What a roofer must not do is negotiate the claim on your behalf or offer to absorb your deductible, both of which are illegal in Texas. Rural Wilson County addresses can mean a longer wait for an adjuster, so document the damage with dated photos the day you find it.
Are Class 4 impact-resistant shingles worth paying for here?
Usually yes. Class 4 means the shingle passed the UL 2218 steel-ball impact test, and most Texas homeowner carriers give a premium discount for a Class 4 roof, so part of the upgrade cost comes back each year. South Central Texas gets meaningful hail. Call your own insurer for the discount on your policy, then have the exact shingle brand and line written into the contract so the rating is documented later.
Does this company hold a GAF, Owens Corning or CertainTeed certification?
None that we could verify. Its own pages name no shingle manufacturer at all, and we found no profile for it in any manufacturer contractor directory, so no manufacturer credential is listed here. Installing a brand and being certified by that brand are different things, and only the second one lets a contractor register an enhanced system warranty. If a manufacturer warranty matters to you, ask which ones the company can actually register.
What are the hours, and does it do more than roofing?
Its contact page lists Monday to Saturday, 7:00am to 7:00pm. Beyond roofing it lists gutter installation and repair, exterior house painting, and on its projects page stucco work, windows and air conditioning damage restoration, describing itself as a full service exterior restoration business. That breadth is useful on a hail or wind loss where the roof is not the only damaged item.
