About
Bison Roofing is a family owned roofing contractor founded in San Antonio in 2004 by Genaro Montelongo. Its San Antonio office is at 1445 Austin Highway, and the company also operates from Alamo in the Rio Grande Valley. The Better Business Bureau lists Genaro Montelongo Jr. as owner and Manny Luera as vice president, records a business start date of August 2004, and has accredited the company with an A+ rating since December 2008. The company is an Owens Corning Platinum Preferred Contractor, the top tier of the Owens Corning contractor network and one that Owens Corning limits to a small fraction of the roofers it certifies. That status is what lets Bison offer the Owens Corning Platinum Protection limited lifetime warranty alongside its own workmanship warranty. The BBB profile also lists GAF, CertainTeed, Versico, Mule-Hide and Thermotek among the product lines it works with. Work splits across residential, multi family and commercial roofing. On the residential side the company promotes Class 4 impact resistant architectural shingles, metal roofing and Spanish tile. On the commercial and multi family side it handles TPO, PVC, metal and other low slope systems, plus storm and hail restoration with emergency tarping. Published Texas coverage runs from San Antonio out to New Braunfels, Georgetown, Austin, Houston, Corpus Christi and the Rio Grande Valley around McAllen. Bexar County is hail and heat country, and Class 4 shingles are the usual response.

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 listing yourself at web.rcat.net/rcat/search.
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.

Bison Roofing, Out of the 3 Companys I spoke with to get my roof work done were some of the most professional people I've dealt with while trying to figure out who I wanted to get my roof done with. Derrick and Robert kept me updated on everything that was going on. I didn't have to reach out to them. I will definitely refer anyone looking to get roof work done needs to seek out Bison Roofing. I can't forget Marz she was on point to with getting the paperwork to me explaining everything in detail. Great Job and thanks for my New Roof.
I called bison roofing and I'm blessed that I got Robert as my roof expert. We did not go with bison for convenience reasons with another company. But he displayed the most professional experience, and exceptional customer experience. He may not have gotten the repair job, but when it comes to replacing my roof. Bison roofing will be the company I call. I'm glad I got to meet Robert. If he is your inspector, you're in good hands. I promise.
Robert and Marz were outstanding to work with! They were very professional, incredibly responsive, and extremely knowledgeable. Any questions I had were answered quickly and they made everything easy to understand. Their expertise and customer service truly set them apart. I can't recommend Robert, Marz, and the Bison Roofing team enough!
I contacted Bison Roofing to provide me a quote for my chimney and surrounding that needed to be fixed. Robert Garcia did the inspection and he was super professional and helpful. I hired them to do the job, it was an easy process and they finished in one day. Also, shout out also to Derick V who was also very professional and friendly! The entire team was great. Highly recommended!!
Got some structural repair work done and from start to finish i found bison roofing and everyone who helped me out to be extremely professional. From the initial inspection all the way up to the repair crew everyone was fantastic. My repair representative Derek did fantastic and his team did great work. Highly recommend them if you are needing professionals to do important repairs.
