Drifted Snow And Buried Drains
Munds Park sits at the south end of our I-17 coverage. Our work as a Munds Park commercial roofing contractor covers lodging, stores, and offices whose roofs hold drifted snow against walls and units for weeks.
Local Roofs
Munds Park roofs carry long mountain winters: heavy snow that lingers for months, then wind that moves it into drifts behind parapets and around rooftop equipment.
Drifts put the most weight and the most meltwater exactly where a flat roof is weakest. We start every Munds Park inspection at the curbs, the parapet walls, and the drains that snow covers first.
Leak Signs
A drift on the roof turns into a stain, a drip, or a sag inside. These are the matches we see most on Munds Park buildings.
Water lands on a ceiling tile right under a rooftop unit after a sunny week on deep snow.
Wind piles snow on the downwind side of each unit. Melt sits above the curb flashing and finds the base seam, so we raise short curbs and reflash them.
Brown streaks run down the inside face of a wall below a parapet, worst in late winter.
Parapets trap drifts several feet deep. Melt soaks the base flashing and the coping joints, so we check flashing height and reseal each coping lap.
Ceiling grid dips mid-span after heavy snow, and interior doors near the walls start to stick.
Drift zones put extra weight near walls and units. We mark deflection on the deck and bring in an engineer when the framing shows strain.
Dripping starts on bright afternoons, stops overnight, and comes back the next day while snow stays on the roof.
Meltwater can't reach a drain under packed snow, so it ponds and backs under laps. We mark each drain and add overflow scuppers at parapets.
Icicles and a sheet of ice form above the main entry, right below the roof edge and gutter.
Snow off a pitched section fills the gutter and refreezes. We check edge metal fastening, gutter hangers, and the path meltwater takes off the eave.
Who Gains
Rebuilding the roof details that drifts attack pays off for the owner, the person running the building, and everyone under a Munds Park roof.
Roof Systems
Two membranes cover most flat commercial roofs here. Rooftop equipment, building size, and winter exposure decide between them.
Lodging and retail roofs with many rooftop units. Heat-welded laps hold where drifts sit against curbs, and white TPO reflects strong summer sun.
Smaller flat roofs on offices and shops. EPDM stays flexible in deep cold, and taped seams with reinforced curb flashing ride out long freeze-thaw stretches.
Roof Trouble
Call and tell us where drifts build up and which rooms leak after a thaw. We start the inspection at those curbs and walls.
How The Work Runs
Warm, dry working weeks are limited here. This is how we line up a Munds Park reroof so it lands inside them.
During fall or spring, we walk the roof and mark drift zones, curb heights, parapet flashing, and every drain. Deck deflection and wet insulation go on the same roof plan.
Membranes, adhesives, and sealants need warm, dry weather, and that season is short at this elevation. Booking in winter or early spring holds a slot between late spring and early fall.
Crews raise short curbs, add overflow scuppers, and set tapered insulation toward drains. Work starts early each morning so open roof areas close before afternoon storms.
Each curb, parapet, and edge is flashed and checked. A final walk with you covers drain locations and a snow plan showing where drifts form and how to reach each drain.

Common Questions
Answers to what Munds Park owners and managers ask about drifts, drains, and timing a roof job.
Late spring through early fall. Most membranes, adhesives, and sealants need warm, dry weather to bond, and at this elevation that window is short, so book well before it opens.
Storms build on many summer afternoons, which is why crews begin early and seal each section before the weather changes. Leaks still get fixed in winter, with temporary dry-ins holding until the season returns.
Coconino County Building and Safety, because Munds Park is unincorporated county land.
Commercial jobs start with a pre-construction meeting with county building staff before the application goes in. The County's parcel viewer confirms the district for an address, and we check the current requirements with the county before work begins.
Drifts hold meltwater above the top of the curb flashing. Wind packs snow on one side of each unit, sun melts the surface, and water sits against the base seam for days.
Low curbs are the usual weak point. Raising the curb and reflashing it above the expected drift line stops most of these leaks.
Sometimes, mainly where drifts pile against parapets and units or where the deck shows sagging. Leave a layer of snow on the membrane and use plastic shovels, since metal blades cut it.
Clearing a path to each drain matters more than clearing the whole roof.
Sagging ceiling lines, sticking doors, new cracks in interior walls, and ponding where the roof used to drain all call for a prompt check after heavy snow.
Coconino County sets ground snow loads by parcel, and drift zones near parapets and units carry more than the open field. An engineer reviews any framing concern.
Fall prep does most of the work. Before snow, drains, scuppers, and gutters get cleared of pine needles and debris and flashings resealed.
During winter, a marked path to each drain lets someone clear it after a storm, and overflow scuppers give water a second exit when a drain freezes.
Repairs fit a roof with dry insulation and a few failed details, such as one curb or a stretch of parapet flashing.
Replacement makes sense when leaks keep moving, insulation is wet across large areas, or seams are open in many places.
