Elevation, Aspect and Ice: The Ravalli County Pattern
Thin air at altitude means intense direct sun even in deep cold. A Hamilton roof can be melting on its south face at midday in air that never gets near freezing, and all of that water has to go somewhere.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Hamilton to a shaded eave that has not been above freezing for weeks, and that is where the ice builds into a wall.
Ice-barrier practice in Ravalli County
Design snow loads in Ravalli County are among the highest anywhere, and the membrane and retention requirements that go with them are not formalities. On an older Hamilton cabin or chalet neither may be present.
What a Crew Does on a Hamilton Roof
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.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Hamilton clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.

Ravalli County Coverage From Hamilton
Crews working Hamilton cover the adjoining communities on the same route — Grantsdale, Corvallis, Pinesdale and Victor — so a storm week usually means one truck handling several addresses in Ravalli County rather than separate trips.
Nearest hub towns with their own crew pages: Missoula, Butte, Helena, Kalispell, Columbia Falls, Belgrade.
During a cold snap Hamilton gets worked alongside the neighboring Ravalli County towns on the same route, with active interior leaks moved to the front of the list.
If water is already inside a property in Hamilton, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
