Why Moscow 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.
That is why mountain roofs dam up on clear, cold weeks that look harmless. South and west faces melt, north-facing eaves and shaded valleys hold the ice, and the pack above keeps feeding it.
Ice-barrier practice in Latah County
Snow retention above doors, walkways and parking is a requirement in most Latah County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
The Moscow Dispatch Process, Step by Step
Crews walk the eaves, valleys and gutter line first and photograph every dam and every point where water is tracking inside, before touching anything. You get shown what they found and quoted the crew-hour rate before work starts.
Then the ice comes off with low-pressure steam, starting wherever water is actively backing up so drainage opens early. Frozen gutters and downspouts are cleared in the same visit, because a cleared eave above a solid block of ice in the gutter dams again on the next cold night.
Why the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.
Why a drainage channel is not removal
Cutting a few channels through a dam so water can get past is quick and it is sometimes sold as ice dam removal. It drains the roof for as long as the channels stay open, which in a Moscow cold snap can be a single night before they close again.
Removing the dam means taking the ice off down to the shingle along the whole affected run, so the eave can drain the way it was built to. It takes longer and it is the only version that holds.
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Moscow, and a postponed start gets explained rather than dressed up.

Neighborhoods and Towns We Reach From Moscow
Crews working Moscow cover the adjoining communities on the same route — Viola, Troy, Genesee and Princeton — so a storm week usually means one truck handling several addresses in Latah County rather than separate trips.
Nearest hub towns with their own crew pages: Lewiston, Coeur d'Alene, Post Falls, Hayden, Sandpoint, McCall.
Crews cover Moscow and the surrounding Latah County towns through the whole season, and during a freeze event they run from first light until dark.
