By the time a roof in Sun Valley has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Sun Valley winter roof services, crews handle commercial ice dam removal across Blaine County.
Why Sun Valley Roofs Dam Up: Altitude Sun on a Deep Pack
Mountain ice dams are a solar problem more than a temperature one. The sun works the pack from above while the air stays cold, so meltwater is produced and refrozen within the same afternoon.

Aspect decides everything here. The sunny plane sheds water that the shaded plane and the shaded eave then lock up, so one side of a roof in Sun Valley is clear while the other carries a wall of ice.
Ice-barrier practice in Blaine County
Design snow loads up here are among the highest in the country, and the membrane and retention details that come with them are not paperwork. On an older Sun Valley cabin neither is likely to be present.
Commercial Ice Dam Removal in Sun Valley: How The Work Runs
Scheduling around tenants
Noise, access, parking and the hours a Sun Valley business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on a Sun Valley building that distinction shows up as a tenant ceiling two floors down.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Sun Valley unit, there is usually standing water up there.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Sun Valley call.
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
