Snow is the load. Rain is the nuisance. Commercial Roofing Flagstaff is a commercial roofing contractor that works from that rule in Flagstaff, AZ. A Flagstaff roof sits near 7,000 feet and holds up under 90 to 97 inches of snow in an average year, which makes it a structure under a long test, not a surface that sheds a shower. We repair, replace, recover, coat, inspect and maintain low-slope and metal commercial roofs, and every job begins with the same question: what is this roof carrying, and where does the water go?
The people who call us are property managers, owners, facility teams and contractors. They have a leak, a decision or a deadline. We give them a walk, a ranked list and a price beside every item.
A commercial roof needs different work at different ages. We handle repair for local failures, replacement when a roof is finished and the recover in between. We apply coatings to dry, worn membranes. We clear drains, reset edge metal and flash curbs.
We install and repair TPO, PVC, EPDM, KEE, modified bitumen, built-up, standing seam and retrofit metal, spray foam, and silicone and acrylic coating systems. The choice among them comes from the building: its deck, its drainage, what sits under it and what the winter does to it.
Inspections come first. We walk the roof, run drone and infrared moisture surveys on larger roofs and write condition reports with photographs. We run preventive maintenance programs, and we document insurance claims. Across the services we offer and the roof systems we install, the walk comes first and the recommendation follows the evidence.
The cold comes back in late September, and the record low sits at minus 30 degrees F. The single-day snow record is 35.9 inches, set on February 21, 2019. Parts of the city were under 24.5 inches by March 2, 2023, after a storm that began on February 28, and officials reported several roofs collapsing. The warnings they put out named sagging ceilings, bowing trusses and severe leaks.
We built our walk around that list. A sag check sits beside every drain check in how we walk a roof. We map drift lines behind parapets and mechanical wells, test drains under a thaw and look at the edges where ice builds. When we see signs of structural movement, we stop and recommend an engineer, because the structure comes before the membrane.
Summer brings its own test. Roughly a third of the year's 20 to 22 inches comes with the monsoon, when thunderstorms are most common in July and August. The same drains that held snowmelt face a downpour a few months later.
Flagstaff has a mix. Downtown, the Railroad Addition holds historic commercial buildings, and since an 1897 ordinance required brick, stone or iron, the older roofs there sit on masonry. Mike's Pike runs industrial, in boxy metal, wooden and concrete buildings. Butler Avenue and Lone Tree Road run near Northern Arizona University. Flagstaff Mall, a single-story center opened in 1979, stands on the east side, and five industrial parks sit along I-40 and I-17.
The large employers bring their own roof questions: Northern Arizona University, Flagstaff Medical Center, the Flagstaff Unified School District and W. L. Gore and Associates. Hospital, campus and school roofs run on calendars and consequences that a warehouse roof does not. A hospital, a campus and a warehouse each need a different property type plan, and an owner's industry decides who approves it and when.
Every job follows four steps. We walk the whole roof, not just the stain. We rank what we find by what spreads fastest and what the building cannot afford. Each item gets a price and a label, patch or fix, with its cost drivers noted: access, equipment, tear-off depth, insulation and the weather window. Then we record the work with dated photographs.
That record feeds the larger decisions. Our capabilities include asset records, capital plans, condition reports, warranty files, due diligence surveys and multi-site programs. They matter most to owners with several roofs, who need an order of attack more than another patch.
We work on occupied buildings and plan around tenants, operations and schedules. Work happens in sections, each closed watertight before the crew leaves, with fumes and debris kept away from entries and air intakes.
Emergency response runs around the clock, all week, holidays included. On an active leak we start with a temporary dry-in as soon as the roof is safe to walk. The permanent repair follows when surfaces are dry and temperatures allow adhesives and welds to work, which in this climate may be days or weeks later. We document the temporary work as temporary, so it gets replaced properly.
We cover Flagstaff and the places around it: downtown, Southside, Butler Avenue, East Flagstaff and Fort Valley in the city, and Bellemont, Williams, Munds Park, Doney Park and the mountain towns beyond. Distance and elevation change the plan, so each of the service areas gets a route, a calendar and a snow assumption of its own.
A price comes after we have seen the roof. Manufacturer warranty terms come from the paper, and repairs follow the method a warranty allows. When the evidence points to a replacement, we show the test results. When it points to a repair, we say that too, and we put the cost of each path side by side.
Call with the building address, the roof type and the last walk date, and we will line up the sag and drain checks. Do it before the next heavy storm.
Low-slope and metal commercial roofs on offices, retail centers, industrial buildings, hotels, schools, medical buildings, hangars and public buildings. The right plan depends on the roof system and what sits under it, so the first walk records both.
Yes, around the clock and on holidays. We open with a temporary dry-in once the roof is safe to walk. Permanent work follows when the surface is dry and the temperature allows the materials to cure.
Moisture and spread. Dry insulation and local defects mean repair. Wet insulation, open seams across the roof or a soft deck mean replacement. We test with infrared and core samples and show both options with their costs.
The building address, the roof type and when the roof was last walked. Those three items let us schedule the drain checks and the sag checks that matter most before a heavy storm.
We plan for them. Sections are opened and closed in a day, noise and fumes stay away from entries and intakes, and the schedule follows the building's hours, whether it is a clinic, a store or a plant.
A walk of the roof with photos, findings and a written scope.
Active leaks, storm damage and blocked drains get a fast response.
