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 licence yourself at web.rcat.net/rcat/search — search #03-0604 or the company name.
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 Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly.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
Texas has no state roofing licence, so how do I vet a Round Rock roofer?
Verify insurance yourself by asking for a certificate of insurance sent directly from the agent, covering current general liability and workers compensation. Check any manufacturer certification on the manufacturer's own site. Then read the BBB record and confirm registration or permitting requirements with the City of Round Rock or Williamson County.
What is the difference between RCAT Member and the RCAT licensed credential?
The Roofing Contractors Association of Texas offers plain membership, which simply means dues are paid, and a separately earned Licensed Roofing Contractor credential (CRRL, RRL or CRL) that requires testing and documented experience. Neither is a government licence, and one does not imply the other.
Does an A plus BBB rating mean a company is BBB Accredited?
No. A rating is BBB's own assessment based on complaint history and other factors, while accreditation is a paid membership with additional standards. A company can hold an A plus rating without being accredited, and it is worth checking which one you are looking at.
Is there more than one Cardinal Roofing in Texas?
Yes, and it causes confusion. This listing is the Round Rock business in Williamson County at 1620 Red Bud Lane. There is a separate and unrelated Cardinal Roofing operating in the Dallas Fort Worth area, and other Cardinal named roofers elsewhere in Texas. Check the address and phone before assuming reviews belong to the same company.
Should I choose metal or asphalt shingle in Central Texas?
Standing seam metal costs more up front but lasts longer, sheds heat well and handles hail differently than shingles. Asphalt shingles are cheaper and faster to repair. For a hail exposed Central Texas roof, ask for pricing on both and for the impact rating of whichever product is proposed.
What are Class 4 impact resistant shingles and are they worth it here?
Class 4 shingles pass the UL 2218 steel ball impact test, the top impact classification. Many Texas insurers offer a premium discount for them. Central Texas gets regular spring hail, so they are usually worth pricing, but confirm the discount with your own carrier first because the credit varies.
Do I need a permit to replace a roof in Round Rock or Williamson County?
Texas has no statewide building code enforcement for reroofing, so it is set locally. Round Rock, Georgetown, Hutto, Cedar Park and unincorporated Williamson County all have their own rules. Ask who is pulling the permit and make sure that is written into the contract.
How does a hail insurance claim usually work?
You file with your own carrier. An adjuster inspects and issues a scope and an actual cash value payment, with recoverable depreciation released once work is completed and invoiced. A roofer can document damage and meet the adjuster, but cannot negotiate the claim for you unless separately licensed as a public adjuster.
Can a contractor cover my deductible?
No. Texas law makes it unlawful for a contractor to pay, waive, rebate or absorb an insurance deductible. Any offer to do so should end the conversation, because it usually means the scope or the price has been inflated somewhere else.
What should be in the contract before I sign?
The manufacturer and product line, the price for replacing damaged decking, underlayment, flashing and ventilation details, who pulls the permit, the exact workmanship warranty length and what voids it, the payment schedule, and the cleanup and nail sweep commitment. Avoid large deposits and avoid contracts that hinge on a specific insurance settlement figure.
