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.

RegionHarlingen
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 Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly.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
Does Texas require a state roofing license?
No. Texas has no statewide roofing license. Trust is established through insurance, manufacturer certifications, and BBB or trade association standing rather than a state license.
What is the difference between an RCAT Member and an RCAT Licensed Roofing Contractor?
Plain RCAT membership means dues are paid; the separately earned Licensed Roofing Contractor credential (CRRL/RRL/CRL) is a different, higher bar. No RCAT record for this company turned up in a keyword search, so ask the company directly which status it holds.
Does Cameron County fall under Texas windstorm insurance rules?
Yes. Cameron County is one of the 14 first-tier Gulf Coast counties covered by the Texas Windstorm Insurance Association's WPI-8 program, and Castillo Roofing references TDI windstorm certified standards on its own site.
What does an Atlas Pro Gold or CertainTeed Shingle Master credential mean?
These are manufacturer-issued installer certifications that require training and a track record of properly installed roofs, which can extend the manufacturer's warranty coverage compared to a standard installation.
Who issues roofing permits in Harlingen?
Texas has no statewide building code, so permitting is handled locally. Confirm with the City of Harlingen whether your project needs a permit and have the contractor pull it.
What should I confirm before signing a contract with any roofing company?
Ask for current proof of general liability insurance, a written scope of work with materials specified, manufacturer warranty terms, and how the company documents storm damage for an insurance claim.
What roofing materials does Castillo Roofing install?
Its own site lists Atlas, Malarkey, and CertainTeed shingle lines, McElroy Metal standing seam systems, and Mulehide and Thermotek products for low-slope roofs.
Does Castillo Roofing offer free inspections?
Yes, its own site advertises free roof inspections.
What area does Castillo Roofing serve?
Its own site lists Harlingen, McAllen, Brownsville, South Padre Island, San Benito, Los Fresnos, Pharr, Alamo, San Juan, Weslaco, Mercedes, La Feria, Mission, and Edinburg.
How can I verify a Rio Grande Valley roofing company's standing?
Look for a Google Business Profile with reviews, check for manufacturer certification badges on the company's own site, and ask for references from recent local jobs, since Texas has no state licensing board to check instead.
