About
Shamrock Roofing & Construction is a multi-state roofing company headquartered at 7899 Frontage Rd, Overland Park, Kansas, operating branches across Missouri, Kansas, Arkansas, Oklahoma, Nebraska, Iowa, Colorado and Texas. Its Sherman, Texas location, branded locally as Shamrock Roofing and Construction Texoma, is registered at 1521 S Sam Rayburn Fwy and holds its own BBB profile, separate from the parent company's Kansas/Missouri BBB filing, with an A+ rating and BBB accreditation dating to March 28, 2022.
The parent company's own site traces the Shamrock name to a family roofing business founded in 1977 in the Kansas City area. The Sherman-specific BBB filing shows a business start date of May 1, 2014 for that entity, so it is unclear whether the Texoma branch has been operating locally since then or whether that date simply reflects when this Texas registration was filed; both figures are reported here rather than picking one.
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.

City/county registration
Not checked for ShermanTexas has no state roofing licence, and city rules differ: some require contractor registration, some run a voluntary registry, some neither. Ask this company and your local permit office.
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 Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly.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.
Does Texas require roofing contractors to hold a state license?
No. Texas has no statewide roofing license. Roofers are not regulated by a state licensing board the way electricians or plumbers are. Homeowners should confirm a contractor's liability insurance directly, ask for references, and check for registrations such as an RCAT (Roofing Contractors Association of Texas) membership.
Is Shamrock Roofing & Construction listed with the Roofing Contractors Association of Texas (RCAT)?
We searched the RCAT member directory at web.rcat.net by company name and did not find Shamrock Roofing & Construction listed as of our research. RCAT membership is voluntary, so this is not by itself a red flag, but homeowners who want RCAT-verified credentials should ask the company directly or search the RCAT site themselves.
How can I verify a roofing contractor's insurance before signing a contract?
Ask for a certificate of insurance (COI) naming you or your job address, then call the listed carrier to confirm the policy is active and covers general liability and workers' compensation. A verbal assurance is not proof.
What is a Class 4 impact resistant shingle, and is it worth it in Grayson County?
Class 4 shingles pass the toughest UL 2218 impact test and resist cracking from hail. The Sherman/Texoma area of North Texas sees regular hail activity, so it is reasonable to ask any roofer, Shamrock included, whether Class 4 shingles are available and whether your insurer offers a premium discount for them.
Does the City of Sherman require a permit for a roof replacement?
Texas has no statewide building code, so permitting rules are set city by city and county by county. Homeowners in Sherman should confirm directly with the city or Grayson County building/permits department whether a residential reroof needs a permit and inspection before work begins.
What should I ask a roofer before signing a contract?
At minimum: proof of current liability insurance, a written scope of work and materials list, manufacturer and workmanship warranty terms, a payment schedule that does not require full payment upfront, and whether the contractor pulls any required permits. For a multi-state company like Shamrock, it is also worth asking whether the crew and project manager are local to Texoma.
How does a hail damage insurance claim typically work in Texas?
After a hailstorm, you file a claim with your insurer, who sends an adjuster to inspect the roof. Some contractors offer to meet the adjuster on site and help document damage, but you should still read your policy and get an independent opinion before agreeing to a repair scope.
What is the difference between a roof repair and a full roof replacement?
A repair addresses a specific damaged area, like a leak or missing shingles. A full replacement strips the roof to the deck and installs an entirely new system. A qualified roofer should explain why one is recommended over the other for your roof's age and condition.
How long does a typical roof replacement take?
Most residential roof replacements in Texas take one to three days depending on roof size, materials, and weather. Ask any contractor you are considering, including Shamrock, for a written timeline estimate.
What warranty should I expect on a new roof?
Most shingle manufacturers offer a limited materials warranty, often 25 to 50 years depending on the product line, plus a separate, typically shorter, workmanship warranty from the installer covering labor. Shamrock advertises a lifetime workmanship warranty on its own site; ask for the exact written terms as they apply to the Sherman branch.
