About
Expertise Roofing is a family owned roofing contractor based in Von Ormy, in southwest Bexar County, and it markets itself across the wider San Antonio area. The owner is Gilbert A. Alcantara. The Better Business Bureau records the business as having started on 1 January 2011, which makes it one of the longer running small roofing outfits on the south side of the county. The company's own site describes it as a trusted, family owned local business for roof installations and roof repair.
The service list on the company's own website is unusually detailed for a business of this size. Alongside full roof replacement and repair it covers flat roof replacement, shingle roof systems, roof inspections, fascia replacement, skylights, ventilation and vent installation, new construction roofs, chimney leak repairs, rotted decking replacement, wall flashing, waterproofing, drip edge and metal valley installation, and emergency dry in after a storm. Published service areas run well beyond the city, taking in Pleasanton, Jourdanton, Poteet, Somerset, Elmendorf, Castroville, Lytle, Stockdale and Universal City.
Von Ormy and San Antonio are inland, so windstorm certification does not apply. The company's own pages point at severe weather, storm damaged roofs and hail damage as the reasons homeowners call. That matches the Central Texas pattern: hail bruising, then heat and UV ageing the shingle mat and the rubber and sealant around penetrations until water finds a way in.

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
Is Expertise Roofing licensed by the State of Texas?
There is no such thing. Texas does not license roofing contractors at state level, so no roofer in Von Ormy or San Antonio holds a state roofing license. Check insurance, city registration where the work is being done, voluntary industry credentials and the company's complaint history instead.
Is Expertise Roofing BBB Accredited?
No. The BBB has a file on the company that was opened in August 2018, and that file records the business as not BBB Accredited. Accreditation is a paid programme, so its absence is not evidence of poor work, but you should not be told the company is accredited when it is not. Read the BBB file yourself using the link on this listing.
Is Expertise Roofing an RCAT member?
We searched the Roofing Contractors Association of Texas member directory for Expertise Roofing and no record came back. RCAT membership is voluntary and plenty of established Texas roofers have never joined, so this tells you nothing about quality. It only means there is no RCAT record for us to point you at.
What is the difference between an RCAT Member and an RCAT Licensed Roofing Contractor?
A Member simply pays association dues. The Licensed Roofing Contractor credential, shown as CRRL, RRL or CRL, is earned separately through testing and experience and appears with a license number on the RCAT directory record. The two are not interchangeable, and neither is a government license.
Does a Von Ormy or San Antonio roof need windstorm certification?
No. WPI-8 certification and TWIA windstorm insurance apply only to the 14 first tier Gulf Coast counties. Bexar County is inland. Anyone quoting windstorm certification for a roof in Von Ormy is either confused or padding the invoice.
What are the real risks to a roof in this part of Texas?
Hail first. Central Texas sits on the southern end of hail country and repeated small hail bruises shingle mats long before anything looks obviously broken. Then heat and UV, which harden asphalt, crack pipe boots and lift sealant off flashing. Wind driven rain exploits whatever those two have opened up.
Should I pay for impact resistant Class 4 shingles?
It is worth pricing. Class 4 is the top rating under the UL 2218 impact test, and many Texas insurers discount premiums for a Class 4 roof, which recovers part of the upgrade cost over the life of the roof. Ring your own insurer for the actual discount, then have the contractor name the specific product and rating on the written proposal.
What does emergency dry-in actually mean?
It is temporary weatherproofing to stop water entering while a permanent repair is arranged: usually underlayment or tarping over the opened area, mechanically fastened and sealed. It is not a repair, and it should be priced and documented separately so it does not muddle the insurance scope for the real work.
Who pulls the permit for roof work in San Antonio and Bexar County?
Texas has no statewide building code, so permitting is set locally. Inside San Antonio city limits, roofing work generally requires a permit through the city's Development Services Department and the contractor should be registered with the city. In unincorporated Bexar County and in small towns like Von Ormy the requirements differ, so confirm in writing who is responsible. Never pull the permit in your own name for a contractor.
What should be in the written proposal before I sign?
The exact shingle brand, line, colour and impact rating. Whether underlayment, drip edge, pipe boots, valley metal and ventilation are being replaced or reused. An allowance and unit price for rotted decking found after tear off. Who pulls the permit, who hauls the debris, the workmanship warranty term, and the payment schedule. Ask for a certificate of insurance sent to you directly by the insurer.
