A roof system has to survive the winter first and look good second. Flagstaff, AZ has freezing weather back by late September, a record low of minus 30 degrees F and 90 to 97 inches of snow in an average winter. Commercial Roofing Flagstaff installs and repairs the main commercial systems, and we pick among them by how each one handles snow, ice, meltwater and a hard monsoon.
No system is right for every building. The deck, the insulation, the drainage and the use below decide the choice.
Single-ply membranes suit low-slope roofs with parapets and drains. TPO and PVC are heat-welded at the seams, which makes a continuous sheet that resists meltwater. EPDM is a rubber sheet with taped or bonded laps, and KEE is a ketone-based membrane used where chemical or grease exposure matters. Each one needs clean seams and a dry deck.
Plies of asphalt and reinforcing fabric make a roof with redundancy. Modified bitumen is torched, mopped or self-adhered in sheets. Built-up roofing stacks several plies under a surfacing layer. Both take foot traffic better than many sheets and repair well in cold weather with the right materials, though torch work needs a dry, clear roof and strict fire precautions.
Metal roofs shed snow and last. A standing seam metal roof hides its fasteners and moves with temperature. A metal roof retrofit adds a new panel system over an old roof where the framing can carry it. The catch is slide: snow lets go all at once, so snow guards and walkway planning come with every metal job.
Spray polyurethane foam adds insulation and a continuous surface to irregular roofs. Silicone and acrylic roof coatings restore a worn but dry membrane and reflect heat. All three need a dry, clean substrate and workable temperatures, which in this country means late spring through early fall.
Moisture testing comes before any of them. A coating or a foam layer over wet insulation traps the problem. We check with infrared and core samples, then recommend.
Downtown brick buildings in the Railroad Addition, metal and concrete buildings along Mike's Pike and rooftop-equipment retail near Butler Avenue each lean toward different systems. We start from the existing roof, test it and weigh cost, life and the winter that follows. The result is a priced option for each workable system, with the trade-offs written plainly.

Several do, if the deck and drains are right. Standing seam metal sheds snow, welded single-ply resists meltwater, and layered systems take traffic. Structure, drains and snow guards matter more than the brand on the label.
Sometimes. A recover works when the insulation is dry and the deck is sound. We test with infrared and core samples, then tell you whether a recover or a tear-off fits.
Well, when applied to a clean, dry, sound roof at a workable temperature. Coatings fail when applied over wet insulation or dirty surfaces, so prep and testing come first.
Yes. Fasteners and seam sealant need yearly checks, and snow guards belong over doors and walkways because snow slides in sheets.

Active leaks, storm damage and blocked drains get a fast response.
