Commercial Roofing in Arizona is a different trade than it is anywhere else. Your membrane bakes at 160 degrees on a July afternoon, then takes 70 mph monsoon gusts in August. We install and restore TPO, EPDM and modified bitumen systems on warehouses, retail centers, schools and industrial plants across the state, and we spec every roof for the climate it actually sits in.
Commercial Roofing in Arizona means installing, restoring and maintaining low-slope membrane systems on buildings where a leak shuts down business. That covers TPO membrane, EPDM membrane and modified bitumen, plus the flashing, scuppers, drains and penetrations that fail first. We tear off failed systems, install new insulation and cover board, weld or adhere the membrane, and detail every curb and pipe boot so water leaves the roof instead of finding your ceiling tiles.
Most Arizona commercial buildings sit on flat or low-slope decks, and that geometry is unforgiving. Ponding water on flat roofs, clogged scuppers and drains, UV and sun deterioration of roofing materials, and monsoon wind damage all show up on the same roofs. If you own a strip center in Gilbert or a shop in Show Low, an Arizona commercial roofing contractor who understands ponding and drain flow matters more than the brand of membrane on the roll.
Every commercial project starts with a full roof assessment and a written scope. From there, the work covers membrane installation or restoration, flashing and drain detailing, and a final inspection with warranty paperwork. Add-ons like insulation upgrades, skylight replacement and structural deck repair are priced separately so you can see exactly what each item costs.
We walk the entire roof, photograph deficiencies, and check for wet insulation with a moisture meter and infrared thermal camera. You get a condition report with photos and a clear repair-versus-replace recommendation before any work is scheduled.
Hot-air welded TPO, adhered or mechanically fastened EPDM, and torch or self-adhered modified bitumen. We install to manufacturer specification so the material warranty stays valid, and we probe every seam before sign-off.
New metal flashing at walls, curbs and expansion joints, plus scupper and drain rebuilds. These details cause most commercial leaks, so we treat them as the priority, not an afterthought. Every penetration gets a proper boot or pitch pan.
We replace saturated insulation and add polyiso or cover board where the assembly needs it. Higher R-value cuts cooling load in Arizona summers, and cover board protects the membrane from foot traffic and hail impact.
Flood-testing drains, seam probing, and a magnetic nail sweeper pass over the lot. You receive manufacturer warranty documents, photos of the finished roof, and a recommended maintenance schedule for the next 12 months.
We walk the roof, photograph every deficiency, and run a moisture meter and infrared thermal camera over wet insulation. You get a condition report with photos and a repair-versus-replace recommendation. Most assessments take 60 to 90 minutes on a typical 20,000 square foot roof.
You receive a line-item scope: membrane type and thickness, insulation R-value, flashing details, drain work and warranty terms. No allowances, no surprises. We price repairs, restoration and full replacement side by side so you can compare the real numbers.
We confirm dates around your business hours and tenant needs. Materials get staged the day before, roof anchors and a ladder stabilizer go up for crew safety, and we protect HVAC units, skylights and signage before any tear-off starts.
Crews strip the old system with a shingle ripper and pry bar, inspect the deck for dry rot, then install insulation, cover board and the new membrane. TPO seams are hot-air welded; EPDM is adhered or mechanically fastened. A 20,000 square foot TPO replacement runs 5 to 8 working days.
We flood-test drains, probe every weld and seam, and walk the perimeter for fasteners with a magnetic nail sweeper. You get warranty paperwork, photos of the finished roof, and a maintenance schedule. Final walkthrough takes about an hour with your facility manager.

Finds wet insulation under a dry membrane by reading temperature differences. It turns a 20,000 square foot roof into a map of problem areas in under an hour instead of a dozen test cuts.
Confirms what the thermal camera suggests. We probe the membrane and insulation at suspect points to measure actual moisture content and decide whether a section can be saved or must come out.
Documents tall or steep sections and gives you aerial photos of the finished roof. Useful for multi-story buildings and for insurance claims where visual evidence matters.
Fuses TPO seams into a single membrane. We probe every weld by hand after cooling, because a seam that fails in year three is the most common cause of TPO leaks.
Keeps crews tied off and ladders secure on every visit. OSHA-compliant fall protection is not optional on a commercial roof, and it is part of how we keep the job insured and clean.
Runs over the parking lot and staging area at the end of every workday. It pulls stray roofing nails and fasteners before they end up in a customer's tire.
A 30,000 square foot retail roof in Gilbert had ponding water 2 inches deep near two scuppers. Ceiling tiles stained after every storm, and two contractors had quoted a full tear-off at six figures.
After: We rebuilt both scuppers, re-sloped two low areas and resealed the surrounding membrane. Total cost came in under $18,000. The roof has stayed dry through two full monsoon seasons since.

A school roof in Show Low had a 22-year-old modified bitumen system with cracked flashing, wet insulation over the gym and active leaks. Work had to finish before the school year started.
After: We tore off the old system, replaced saturated insulation, added cover board and installed 60-mil TPO across 24,000 square feet in six working days. The roof passed inspection and was watertight before the first day of class.

A monsoon gust peeled back 400 square feet of membrane at the corner of a Cave Creek shop roof. Water was entering over the office ceiling and the owner needed it stopped before the next storm.
After: We tarped the same afternoon, then replaced the lifted section, upgraded the edge metal and re-fastened the perimeter to spec. The permanent repair was done in three days and the office stayed dry.
Book this service →Most commercial roof failures in Arizona trace back to five things: water that cannot leave the roof, seams that open under thermal cycling, penetrations that were never detailed right, UV breakdown of the membrane, and wind uplift during monsoon season. We fix the cause, not the stain on your ceiling tile.
Ask a pro →For most Arizona low-slope buildings, 60-mil TPO is the best all-around choice. It reflects sunlight, holds up to UV and thermal expansion, and welds into strong seams. EPDM is a close second for large, simple roofs and costs less per square foot. Modified bitumen works well on smaller roofs with lots of penetrations. We spec the material to your deck, slope and drainage, not to a sales sheet.
Typical 2026 pricing runs $6 to $12 per square foot for a full TPO or EPDM replacement, and $1.50 to $3.50 per square foot for recoating or restoration. Repairs usually land between $450 and $3,500 depending on access and scope. Insulation R-value, tear-off layers, height and drain work move the number most. We give you a fixed written price before any work starts.
Twice a year, minimum. Schedule one inspection in spring before monsoon season and one in fall after it. Arizona roofs take extreme UV and thermal cycling, so seams, sealants and drains degrade faster here than in milder climates. Buildings over 15 years old or with existing ponding should be inspected quarterly.
Yes. We handle Arizona commercial flat roof repair statewide, from single membrane punctures to full drain and flashing rebuilds. Most repairs are completed in one visit, and we carry common TPO, EPDM and modified bitumen materials on the truck. If the repair is not worth the money, we tell you and price the replacement instead.
We dispatch commercial roofing crews across Arizona, from the Phoenix metro out to the high country and the southern border. One Arizona commercial roofing contractor, one set of standards, whether your building is a strip center, a warehouse, a school or an industrial plant. Below are some of the communities we serve regularly.
Warehouse and light-industrial roofs on the east valley edge. We handle TPO replacement, drain rebuilds and monsoon damage repair for buildings exposed to open-desert wind.
↗ 02 GilbertRetail centers and office buildings with older, undersized drainage. We rebuild scuppers, re-slope low spots and restore membrane instead of defaulting to a full tear-off.
↗ 03 Cave CreekRidge-top commercial buildings that take the full force of monsoon gusts. Edge metal, perimeter fastening and post-storm membrane repair are our most common calls here.
↗ 04 YoungtownSmall commercial and multi-tenant buildings in the west valley. We provide repair-first assessments, recoats and maintenance programs sized for smaller roofs.
↗ 05 MayerHigh-country commercial roofs with freeze-thaw and snow load. We spec heavier membrane and hail-rated assemblies, and we renew sealants before winter.
↗ 06 ParksElevation and cold swings shorten sealant life on Parks commercial roofs. Twice-a-year inspections with penetration resealing keep these buildings dry through the freeze season.
↗ 07 Skull ValleyRural commercial and ranch-support buildings where access takes planning. We stage materials carefully and complete TPO and modified bitumen work in fewer, longer visits.
