About
Great Barrier Roof is a commercial roofing contractor headquartered at 3 Grogans Park Drive, Suite 220 in The Woodlands. The company, which also presents itself as Great Barrier Roof Systems with the tagline We love your roof!, focuses on commercial roof installation, restoration, maintenance programs, and roof safety. It promotes fluid-applied restoration and coating systems from manufacturers including American Weatherstar, Western Colloid, Uniflex, and Everest, alongside CertainTeed, GAF, and Mule-Hide products; those manufacturer relationships are stated by the company and were not verified in manufacturer directories.
The company says it self-performs with in-house crews, which it claims saves clients 10 to 30 percent, and cites 30 years of roofing experience with commercial coverage beyond Texas. Its older domain greatrooferbill.com now redirects permanently to greatbarrierroof.com, so Great Barrier Roof is the current public brand for the same business.

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.

City/county registration
No government registration in The WoodlandsThe Woodlands is a township, not a city, and Montgomery County does not enforce building codes on single family homes. Deed restrictions still apply, so check with The Woodlands Township before work starts. No city or county body registers roofers or inspects this work here, so a contractor's insurance and RCAT standing carry more weight than usual. Ask to see both.
Status Current in the RCAT directory (no published licence number for this record)
RCAT member ID1182 (member since 2022)
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.
Commercial work only, per its website: commercial roof installation, restoration, maintenance programs, and roof safety, with an emphasis on fluid-applied restoration and coating systems.
What is commercial roof restoration versus replacement?
Restoration applies a fluid coating system over a sound existing roof to extend its life, usually at a fraction of replacement cost and with less tenant disruption. It only works when the existing roof and insulation are still in good enough condition, which an inspection should establish.
Is Great Barrier Roof state licensed?
Texas has no state roofing license for any contractor. Trust signals for a commercial roofer are verified insurance, association standing such as RCAT membership, references, and manufacturer approved-applicator status for the system being installed.
What does RCAT Member mean?
It means the company pays dues to the Roofing Contractors Association of Texas. It is not the same as RCAT's separately earned Licensed Roofing Contractor credential, so ask the company which it holds.
Are the manufacturer logos on its site certifications?
The site displays CertainTeed, GAF, Mule-Hide, American Weatherstar, Western Colloid, Uniflex, and Everest as systems it works with. These are stated by the company. For a coating or membrane warranty, ask the manufacturer to confirm the contractor's current approved-applicator status.
Who handles permits for roofing in The Woodlands?
The Woodlands is not an incorporated city and has no city permitting office. Depending on the property, oversight can involve Montgomery County requirements and The Woodlands' own development standards and covenants, so ask the contractor which approvals apply to your building.
What insurance should a commercial building owner verify?
A certificate of general liability insurance with limits appropriate to the building, sent directly from the insurer, plus workers compensation or equivalent coverage for crews. Commercial landlords and property managers should also ask to be named as certificate holder.
Why does in-house labor matter on a commercial roof?
Self-performing contractors control training, safety, and quality directly instead of passing the job to subcontractors. Great Barrier Roof states that it uses in-house crews; ask any bidder who will actually be on the roof.
How does hail affect commercial roofs in the Houston region?
Hail can bruise membranes, crack coatings, and dent metal, often without leaks appearing immediately. After a storm, a documented inspection protects your insurance position, and a maintenance program catches slow damage before it becomes interior leaks.
Can a contractor absorb my insurance deductible in Texas?
No. Texas law prohibits contractors from paying, waiving, or offsetting an insurance deductible, and carriers can require proof of payment. That applies to commercial claims handling discussions as well.
