US-89 Metal Roofs And Snow
We are a Doney Park commercial roofing contractor for shops and small commercial buildings on US-89. We install, repair, and replace metal roofs so sliding snow lands clear of doors, parking, and walkways.
Local Roofs
Doney Park lies northeast of Flagstaff along US-89, and many of its shops, garages, and small commercial buildings carry pitched metal roofs. Metal sheds snow well, yet a full slope letting go at once lands hard on whatever sits below the eave.
On these buildings we start at ground level, noting where people walk, park, and enter, then check snow guards, panel ends, and fasteners on the roof.
Leak Signs
Owners usually spot the trouble at ground level first. Each pair below links what shows up around the building to the roof detail behind it.
Snow crashes off the eave and buries the main entrance or a service door after one warm afternoon.
Nothing holds the snow on the slope above that door. Rows of snow guards over entrances let it melt in place or drop in small amounts.
Vehicles parked along the eave side come back with dents, broken mirrors, or cracked windshields after a thaw.
The eave drops snow straight onto the parking row. Guards spaced for the panel length, or parking moved to the gable end, keep cars clear.
Meltwater from the roof refreezes on a sidewalk or ramp below the eave, and the same patch ices over every night.
Sliding snow rips gutters off or bends them so water spills at one spot. We set heavier gutter brackets and edge trim built for the snow load.
Water shows up along a wall or window head near the eave once snow starts moving on the roof.
Sliding snow drags on the panels and loosens fasteners at the panel ends. We replace worn fasteners and refasten the ends and eave trim.
Orange streaks run down the wall below the roof line, usually beneath a cut panel edge or a lap.
Field-cut panel edges rust first, and scraping snow speeds it up. We treat or replace corroded panel ends before rust spreads under the seams.
Who Gains
On a Doney Park metal roof, the gains come from controlling where snow lands and keeping the panels tight for decades of winters.
Roof Systems
Many buildings here pair a pitched metal roof with a low-slope addition. These two systems cover both.
Shops and small commercial buildings with pitched roofs, plus retrofit metal over a tired low-slope roof after a structural check. Snow guards are laid out with the panels.
Low-slope additions and lean-to roofs behind a metal building. EPDM stays flexible in deep cold, and we tape and roll every seam before closing a section.
Roof Trouble
Call and tell us which door or parking row takes the snow. We will look at the slope above it and the guards it needs.
How The Work Runs
Metal jobs here follow one order, set by where snow falls and when the weather allows safe work on a pitched roof.
First we walk the ground around the building and mark doors, walkways, and parking under each eave. Then we check panels, fasteners, snow guards, gutters, and any low-slope sections on the roof.
Guard rows, spacing, and attachment are matched to the panel type, slope, and the parcel's ground snow load. Coconino County Building and Safety confirms what permit the roof work needs.
Crews remove damaged panels, repair any deck or framing problems found underneath, and set new panels with fastened ends. Each section is closed and trimmed before afternoon storms roll in.
Together we walk the roof and the ground below it, checking guard rows over each door, gutter brackets, seams, and the edge metal at every eave.

Common Questions
Answers to what Doney Park owners and managers ask about metal roofs, sliding snow, and roof work on their buildings.
Metal lasts the longest, often 40 years or more, while EPDM runs about 25 to 30 years and TPO about 20 to 30.
Installation, membrane thickness, drainage, and upkeep all shift those numbers. Loose fasteners, rusting cut edges, and sliding-snow damage shorten metal. Failed seam adhesive, punctures, and edge uplift shorten EPDM. Weak welds, ponding, and foot traffic shorten TPO.
Coconino County Building and Safety, because Doney Park is in unincorporated county land.
The County asks for a pre-construction meeting with building staff before a commercial application, and we confirm current requirements before work begins.
It depends on the panel type, the roof slope and length, and the ground snow load for the parcel.
Longer runs and heavier loads call for more rows, set closer to the eave and directly over entrances. Clamp-on guards fit standing seam, while exposed-fastener panels use a different mount.
Yes, on most standing-seam and ribbed panels, after a check of panels and fasteners, because guards push the snow load onto the attachment points.
Loose or rusted fasteners get replaced before any guards go on, along with worn panel ends and eave trim.
Repair works when the panels are intact and the trouble sits in fasteners, sealant, trim, or a few damaged sheets.
Replacement makes more sense when rust has spread past the cut edges, panels are holed or buckled from sliding snow, or leaks return across the whole roof.
Most eave leaks come from loose panel ends or ice backing up under the trim.
Sliding snow tugs at each panel's bottom end and works fasteners loose, and ice at a cold eave pushes meltwater under closures and laps. We refasten the ends and replace closures.
We close off the eave side under active work and move entry to a protected door when needed.
Materials and any crane stay away from entrances, parking, and fire lanes. Panels are replaced one section at a time so the building is dry each night.
