STX Roofing – Experts Serving Southeast Texas for Decades
STX Roofing is a veteran-owned commercial roofing contractor in Houston, TX, serving property managers, business owners, HOAs, and general contractors across Southeast Texas. The company is owned by Russell Mullin, a U.S. Air Force veteran who brings a military standard of service to every project. We install, replace, repair, and restore commercial roofing systems on industrial facilities, retail plazas, warehouses, multi-family properties, and office buildings.
We carry GAF Master Elite, GAF Coating, IKO Commercial, and CertainTeed ShingleMaster certifications. We’re bondable to $750,000. And we operate one company across both residential and commercial — which means the same standards govern a $4,000 repair and a $400,000 multi-building replacement.
STX Roofing Experts Tackle All Commercial Roof Types
Our Commercial Roofing Company provides complete roofing care, from inspections to storm damage repair services:
- Roof Installation – For new construction or expansions, we install long-lasting systems tailored to your property’s needs.
- Roof Replacement – When aging systems fail, we remove and replace your roof with a modern, high-performance option.
- Roofing Repairs – We respond quickly to roof leaks, storm damage, and surface failures with targeted, lasting repairs.
- Storm Damage Repairs – From hail to hurricanes, we restore roofs affected by extreme weather and assist with insurance claims.
- Roof Coatings & Restorations – Restore an aging flat roof with seamless coatings that resist water, reflect heat, and save you money.
Ignoring damage can lead to major expenses. Issues like punctures, ponding water, open seams, loose fasteners, or blisters can quickly escalate. Our team identifies and addresses these vulnerabilities before they compromise insulation or decking.
We believe fast, informed action is the key to preventing costly replacements—and protecting your investment.

Why STX for Commercial Roofing
Veteran-led with bond capacity
Property managers and general contractors care about two things on the trust side: who runs the company, and whether it can carry a bond on a real project. STX Roofing is owned by Russell Mullin, a U.S. Air Force veteran, and we’re bondable to $750,000. Those two facts tell most B2B buyers what they need to know.
One team for residential and commercial
Some commercial roofers don’t do residential, and most residential roofers won’t touch commercial. We do both. That matters when an HOA needs roofs on individual townhomes and shared community buildings, or when a property manager has a mixed portfolio. Same standards, same crews, one point of contact.
Houston-specific system knowledge
Houston commercial roofs face conditions other markets don’t — roughly 50 inches of rainfall a year, UV intensity that breaks down membranes faster than the Midwest, thermal cycling that stresses flashing, and Gulf Coast hurricane exposure. Hurricane Beryl in July 2024 made that last point unmistakable: NRG Stadium’s own roof was damaged. We spec systems for the climate that actually exists, not the climate the manufacturer’s national brochure assumes.
Documented, code-compliant work
Every commercial project includes pre-installation inspection, system recommendation, written scope, code compliance, and detailed completion documentation — useful for tenants, lenders, and insurance carriers.

How We Work With Commercial Clients
- Initial inspection and consultation. We meet on-site, evaluate the existing system, and discuss your operational constraints.
- Custom system recommendation. We recommend the system that fits the building, the budget, and the timeline — not just the one we install most often.
- Written scope and pricing. Itemized, code-referenced, and clear about exclusions.
- Scheduling around your operations. Most commercial work happens with the building still in use. We sequence to minimize disruption — after-hours and weekend work options available for sensitive operations.
- Documented completion. Photos, warranty paperwork, and inspection sign-off.
Frequently Asked Questions
How much does a commercial roof cost in Houston?
Commercial roofing costs vary widely with building size, roof system, and access. A small flat-roof repair might run a few thousand dollars; a multi-building TPO replacement can run hundreds of thousands. We give every commercial prospect a written, itemized scope so the cost is grounded in specifics, not square-foot estimates.
What’s the best commercial roofing system?
Depends on the building. For flat or low-slope commercial roofs in Houston, TPO or PVC single-ply are the most common choices — they handle UV and thermal movement well. Modified bitumen is the right call on some older buildings. Metal makes sense on industrial facilities. We tell you which system fits your building, not just the one we sell most.
How long does a commercial roof last?
Properly installed single-ply (TPO, PVC) systems are designed for 20 to 30 years. Modified bitumen runs similar. Built-up (BUR) systems can last 20+ years. Roof coatings can add another 10 to 15 years to an existing system if applied before failure.
Do you handle multi-building portfolios?
Yes. Multi-family communities, retail plazas, and property management portfolios are part of our commercial work. We coordinate sequencing across buildings, manage resident or tenant communication, and document each building separately.
Are you bonded and insured?
Yes. STX Roofing is bondable to $750,000 and carries general liability and workers’ compensation insurance. We can provide certificates of insurance with your project named as additional insured.
What warranty do you provide on commercial work?
STX provides a 2-year workmanship warranty on commercial work. Manufacturer system warranties (10–30 years depending on system) apply on top of our labor warranty.
Can you minimize disruption to my business during installation?
Yes. Commercial roof work typically happens with the building occupied. We schedule around your operations, communicate with your team throughout, and adhere to safety standards that protect your employees and customers.
