About
Courtesy Roofing, Inc. is a family run roofing contractor at 15515 Garrett Road, Houston, TX 77044, in Harris County, working the Greater Houston area. The company's own site dates the business to 1992 and describes more than 30 years of service, and the association directory record likewise gives an established date of 1 January 1992. Frank Thornton, a Texas native and U.S. Marine Corps veteran who has been in construction and roofing since 1975, is listed as founder and Director of Operations, and the team page shows several family members and long serving staff, including a field supervisor and an architectural design professional who have been with the company for well over a decade.
Residential work covers roof replacement, repairs for storm, wind and hail damage and missing or broken shingles, and maintenance and inspections for homeowners and insurers. The company installs composition shingles from CertainTeed, GAF, Tamko and Owens Corning, plus metal and flat roofs, and advertises a 7 year workmanship warranty alongside a limited lifetime manufacturer warranty, with premium options covering materials, labour, tear off and disposal for up to 50 years.
Commercial work is a significant part of the business and covers modified bitumen, built up roofing, flat roofs, metal roofs, TPO and waterproofing, with 24/7 emergency repair, roof inspections and insurance claim assistance. Several staff hold CERTA torch safety training and Flintlastic application certificates, which matters on low slope modified bitumen work. The company also carries out remodelling, carpentry, sheetrock, electrical and ceiling tile work. It has been BBB accredited since 20 March 2002 and holds an A+ rating.

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.

InsuranceNot verified by us (we hold no certificate for this company — ask them for a current COI before signing)
City/county registration
Voluntary registry in HoustonRoofer Registration Program. Joining is optional here, so not being listed is not a mark against a company.

Licence boardRCAT, Roofing Contractors Association of Texas (Texas issues no state roofing licence; RCAT runs the licensing programme)
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.

From top throughout this is a top notch contractor. Thankfully they discovered some hidden damage I was unaware of. Every single employee seemed to give the extra 10% and showed pride and attention to detail. They also replaced my chimney cap which had been giving me issues for years.

Frequently asked
Is Courtesy Roofing licensed by the State of Texas?
Texas issues no state roofing licence, so no Texas roofer holds one. What you can check is current general liability and workers compensation coverage, standing in the Roofing Contractors Association of Texas directory, and any registration the City of Houston or Harris County requires for your job.
What does the RCAT "Member" status on this listing mean?
It means the company is a dues paying member of the Roofing Contractors Association of Texas and appears in its contractor directory. That is different from RCAT's separately earned Licensed Roofing Contractor credential (CRRL, RRL or CRL), which an individual earns through testing. Membership is a genuine association credential but it is not the licensed credential and it is not a government licence.
How long has Courtesy Roofing been in business?
The company's own site dates it to 1992 and the roofing association directory record gives an established date of 1 January 1992. The BBB profile records a slightly later start date of 1 January 1993. Either way it has been trading in the Houston area for over 30 years and has been BBB accredited since March 2002.
Does a Houston roof need a WPI-8 windstorm certificate?
No. WPI-8 certificates apply to construction in the 14 first tier Gulf Coast counties in the Texas Windstorm Insurance Association area. Harris County is not one of them. Galveston, Brazoria, Chambers and the other first tier counties are, so if your property is down the coast rather than in Houston, that changes.
What kind of commercial roofing does the company do?
Modified bitumen, built up roofing, flat roofs, metal roofs, TPO and waterproofing, with 24/7 emergency repair, roof inspections and insurance claim assistance. Staff hold CERTA torch safety training and Flintlastic application certificates, which are the relevant credentials for torch applied modified bitumen work.
Which shingle brands does Courtesy Roofing install?
Its residential page lists composition shingles from CertainTeed, GAF, Tamko and Owens Corning, along with metal and flat roof options. Working with several manufacturers means the shingle line is not fixed before the estimate.
What warranty is included?
The company advertises a 7 year workmanship warranty plus the limited lifetime manufacturer warranty on the shingle itself, and says premium warranty options are available that cover materials, labour, tear off and disposal for up to 50 years. Ask which specific manufacturer warranty tier your quote includes, because the top tiers usually require a full system of that manufacturer's components.
Which manufacturer credentials are confirmed?
The CertainTeed SELECT ShingleMaster and CertainTeed Silver Star commercial designations, and the Master Shingle Applicator and Flintlastic Application Specialist certificates held by named staff, are all stated by the company on its own website. We were not able to open CertainTeed's own contractor directory to confirm the current tier, so ask to see the certificates. The BBB accreditation and A+ rating are verified on bbb.org.
Does hail matter for a roof in the Houston area?
Less than in North Texas, but it happens, and Houston roofs also take high wind and long wind driven rain from tropical systems. Class 4 impact resistant shingles carry the top UL 2218 rating and many Texas insurers give a premium credit for them, so it is worth asking your carrier what the credit is before deciding on the upgrade.
What should a Houston homeowner check before signing?
Ask for the certificate of insurance direct from the insurer, a written scope naming the exact shingle line, underlayment and ventilation, the workmanship warranty term in writing, confirmation of who pulls any permit needed by the City of Houston or Harris County, and how any gap between the estimate and the insurance settlement will be handled.
