What commercial roof systems do you install?

TPO, EPDM, modified bitumen, built-up (BUR / hot asphalt), single-ply membranes, standing-seam and galvalume metal, and flat tile. We evaluate the building and help you choose the right system for your application.

What size projects do you handle?

We have handled commercial projects in Yuma for more than 80 years, with project values ranging from small local buildings up to federal-scale work. We scope capacity to match the project.

Do you coordinate with general contractors and property managers?

Yes. On new construction and major renovations we work under the GC or property manager’s schedule and submittal process. We provide submittals, change orders, and as-built documentation.

Can you work after hours to avoid disrupting operations?

Yes. Weekend and off-hours work is available where it matters, such as for storefronts, occupied medical buildings and production facilities. We coordinate our schedule around your operation.

Is a roof coating or restoration a real alternative to replacement?

Sometimes. When the underlying membrane is still sound, a cool roof coating can seal it, reflect solar heat, cut your cooling costs, and add 10 to 15 years of service life without a tear-off. When the underlying system is failed, it is not a defensible choice, and we tell you which situation you are in.

What warranty comes with a new commercial roof?

You get two warranties in writing: the manufacturer system warranty on the roof materials (terms vary by product and manufacturer), and our workmanship warranty on the installation. We walk you through both at project close.

Do you handle commercial roofing emergencies?

Yes. Commercial buildings get the same 24/7 emergency response as residential properties. See our emergency roof repair page.

What licenses do you hold?

ROC L-42 #070448 for commercial roofing, ROC C-42 #069354 for residential roofing, and ROC C-40 #068260 for residential insulation. Bonded and insured in Arizona.

Do you provide documentation for insurance and warranty claims?

Yes. We document every commercial project with photographs, written scope, materials specifications, and as-built details. For insurance claims, that documentation is what your adjuster will typically ask for.

Why does a cool roof matter in Yuma?

Dark commercial membranes can exceed 170°F on Yuma summer afternoons. Reflective surfaces, including white TPO, light-coated BUR, or metal with cool-roof finishes, can run 30 to 50°F cooler, which reduces the load on the building’s cooling system. In Yuma’s climate, that adds up quickly.

Commercial Roof Systems We Install

Commercial roofs in Yuma fail under a different load profile than residential roofs. Surface temperatures climb higher, sun exposure runs longer and the stakes are different, involving a closed business, damaged inventory or a halted production line. The right system depends on your building, your budget, and how long you plan to own it.

TPO (Thermoplastic Polyolefin)

Single-ply white membrane, heat-welded seams, highly reflective. TPO is one of the most common new commercial systems in Yuma because reflectivity directly offsets cooling cost in our desert climate.

EPDM (Ethylene Propylene Diene Monomer)

Durable synthetic rubber membrane, often called “rubber roof.” Long service life, proven in commercial applications for decades. It's a reliable choice where reflectivity is less critical.

Modified Bitumen

Multi-ply asphalt-based membrane. Tough, repair-friendly and well-suited to roofs that take foot traffic for HVAC service.

Built-Up Roof (BUR / Hot Asphalt)

Multiple layers of felt, hot asphalt and surfacing. It's the system our company was built on in 1945. Still chosen today when owners want a proven, heavy-duty flat roof.

Standing-Seam and Galvalume Metal

Cross-cuts residential and commercial. Standing-seam panels and galvalume sheet offer a 40- to 70-year service life, high wind resistance, and strong reflectivity. More on metal roofing →

Roof Coatings and Restoration

Not every tired commercial roof needs to come off. A cool roof coating can restore a sound membrane, cut cooling costs and extend your service life meaningfully. More on roof coatings →

Yuma’s Commercial Roofing Climate

Yuma is one of the most punishing climates in the country for a commercial roof. A few points worth noting:

Surface temperatures over 170°F. Dark commercial membranes can exceed 170°F on summer afternoons. Reflective systems (white TPO, light-coated BUR, metal with cool-roof finishes) can run 30 to 50°F cooler.
Sustained UV. Yuma is one of the sunniest cities in North America. UV degrades plasticizers, sealants, and coatings faster here than most other markets.
Monsoon storms. Short, intense summer storms load flat-roof drainage systems that spend most of the year dry. Drain design and flashing detailing matter.
Haboobs and wind. Dust storms and gust fronts load roof edges, flashings, and mechanical fasteners.

Every system we install in Yuma is designed with these conditions in mind, and our fastening patterns, reflectivity, drain design, and flashings all reflect our local climate.

Project Capacity and Scheduling

We have handled commercial roofing projects in Yuma for more than 80 years, and our portfolio ranges from small local businesses to federal work for agencies like NAVFAC. Our commercial clients typically want three things beyond the roof itself:

Predictable scheduling. We coordinate around your operations. Weekend and off-hours work is available when it's necessary.
Documentation. Project specifications, submittals, change orders and as-builts documented in writing. Photographs of conditions before, during and after.
GC coordination. On new construction and major renovations, we work alongside your general contractor, architect or property manager under their schedule and submittal process.

Credentials That Matter for Commercial Work

Commercial roofing is a credentialing business. Our combined license portfolio is unusual in the Yuma market:

ROC L-42 #070448, Commercial Roofing. Required for commercial roof work in Arizona.
ROC C-42 #069354, Residential Roofing. Mixed-use and multifamily properties often need both.
ROC C-40 #068260, Residential Insulation. We can pair insulation work with roof replacement under our own license.

We are members of the Arizona Roofing Contractors Association and the National Roofing Contractors Association. We are bonded, insured, and licensed. See our full affiliations →

Restoration and Cool Roof Coatings

Not every aging commercial roof is ready to come off. A restoration with a cool roof coating can:

Seal and re-waterproof a sound membrane
Reflect a large share of solar heat, lowering your cooling costs
Extend your service life by 10 to 15 years, deferring a full replacement
Keep your existing roof on your building, which means no tear-off or dumpsters and less disruption

We evaluate commercial roofs honestly. If the underlying system is too far gone, we tell you so. If a coating is the right call, we tell you that too.

Commercial Storm Damage Response

Commercial storm damage gets the same fast response residential does. Active leaks above your inventory, wind damage, or storm debris on your commercial building can halt operations. Call during business hours (Mon–Fri 8 AM – 4 PM) and we move fast on assessment and tarping. See our storm damage repair page for details.
