Thunder City Roofing & Construction Earns Approvals from Five Major Commercial Roofing Manufacturers

OKLAHOMA CITY, OK, UNITED STATES, September 11, 2026 /EINPresswire.com/ -- Approvals from Elevate, Polyglass, Duro-Last, Kingspan and Mule-Hide expand Thunder City Roofing & Construction's commercial roofing capabilities across Oklahoma and Kansas.

Thunder City Roofing & Construction has earned approved contractor status with five major commercial roofing manufacturers, significantly expanding the Oklahoma roofing contractor's ability to bid and complete commercial roofing projects according to manufacturer specifications.

Thunder City now holds approvals with Elevate, an Amrize brand, as a Licensed Contractor; Polyglass USA as a Premio Select Contractor; and Duro-Last, Kingspan and Mule-Hide as an approved contractor.

Together, the approvals strengthen Thunder City's growing commercial roofing division and give the company access to a broader range of roofing systems, manufacturer specifications and warranty options for projects throughout Oklahoma and Kansas.

Built to Bid the Job the Way It Was Drawn

For commercial roofing projects, manufacturer approval can play an important role long before installation begins.

Architects, general contractors, and property owners frequently develop project specifications around particular roofing systems and manufacturers. When a roofing contractor is not approved by the manufacturer specified for the project, the contractor may have to pass on the opportunity or request approval for a substitute product, adding another step to the bidding process.

With approvals from five manufacturers, Thunder City can now pursue more projects using the roofing systems already specified in the construction documents.

“Commercial specs are written around specific manufacturers, and we didn’t want to be the roofer asking for a substitution.” said Brant Holloway, owner of Thunder City Roofing & Construction.

For general contractors managing complex commercial builds, that can make it easier to identify a roofing subcontractor who already meets the qualifications established for the project.

Expanded Commercial Roofing Capabilities

Thunder City's manufacturer approvals collectively cover several of the most widely used commercial roofing systems, including TPO, PVC, EPDM, modified bitumen and roof coating systems. The company also self performs standing seam metal roofing using its own crews.

This range gives Thunder City the ability to work with different roof designs, building requirements and project specifications rather than being limited to a single manufacturer or roofing system.

The commercial division provides new construction roofing, commercial reroofing, roof repairs, restoration, and preventative maintenance for general contractors, commercial property owners and facility managers.

Whether a project involves a new commercial facility, replacement of an aging roofing system or ongoing maintenance of an existing property, Thunder City's expanded manufacturer relationships gives the company additional options for approaching the project based on its specifications and requirements.

A Commercial Roofing Division Built for General Contractors

Thunder City's commercial division is led by Chase Oliver, Vice President of Commercial Operations, and has already completed manufacturer warranted commercial roofing projects for a national restaurant brand.

The company's continued investment in manufacturer approvals is intended in part to make Thunder City a stronger roofing partner for general contractors bidding projects throughout the region.

“When a GC sends over a bid package, the first thing I check is the approved manufacturer list,” said Oliver. “More and more often, we’re already on it. That makes us an easy call for general contractors who need a roofing sub that’s qualified before the bid ever goes in.”

For general contractors, property developers and facility managers, manufacturer credentials can help simplify the process of identifying commercial roofing contractors that meet project requirements before work begins.

Manufacturer Backed Roofing Systems and Warranties

Manufacturer approval is also important after a commercial roofing project is complete.

Many commercial roofing systems offer manufacturer backed warranty options when the project is installed by an approved contractor and meets the manufacturer's applicable requirements. Thunder City's growing list of approvals allows the company to work within those manufacturer programs across a broader range of commercial roofing systems.

The five manufacturer relationships also allow Thunder City to approach commercial projects based on the needs and specifications of the individual building rather than promoting a single roofing system for every application.

This flexibility is particularly valuable as the company pursues larger commercial roofing opportunities across Oklahoma and Kansas.

Oklahoma Roots with a Growing Regional Reach

Thunder City Roofing & Construction is based in the Oklahoma City metro and provides commercial roofing services across Oklahoma, including the OKC and Tulsa markets and communities throughout the state. The company is also licensed to perform roofing work in Kansas.

While the company's commercial division continues to expand, Thunder City remains rooted in the same Oklahoma communities where it built its residential roofing business.

The company has earned more than 230 five star Google reviews from Oklahoma property owners and continues to provide residential roofing, storm restoration, and exterior construction services alongside its growing commercial operations.

Its approach to expansion is reflected in the company's message:

Born Oklahoma. Raised Oklahoma. Roofing Oklahoma.
