Big Sky Ice Dams: Melting on Days It Never Thaws
The pack at this elevation is deep enough to act as its own insulation, which means the surface melts under sun while the base stays locked. Water released at the top has to travel through and under all of it.
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 Big Sky is clear while the other carries a wall of ice.
Ice-barrier practice in Gallatin County
Snow retention above doors, walkways and parking is a requirement in most Gallatin County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
What a Crew Does on a Big Sky Roof
Nothing gets touched until the roof has been walked and photographed. The crew finds every dam, locates where water is getting in, shows you, and gives you the crew-hour rate and a time estimate before the equipment comes off the truck.
Removal then works from the worst point outward, so water starts draining early rather than at the end. Gutters and downspouts frozen solid get steamed through in the same visit — leaving them means the eave dams again within days.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Big Sky house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.
Steep, high and awkward Big Sky roofs
Pitch and height change the job more than ice thickness does. A walkable ranch eave is a ladder and a lance. A three-story roof with a steep pitch means anchors, rope, staging and two people where one would otherwise do.
Crews quote on that honestly. If a property in Big Sky needs a longer setup, it is said on the phone rather than discovered at the end of the invoice.
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.

Gallatin County Coverage From Big Sky
Crews working Big Sky cover the surrounding Gallatin County addresses on the same route, so a storm week usually means one truck handling several properties rather than separate trips.
Nearest hub towns with their own crew pages: Bozeman, Belgrade, Livingston, Butte, Helena, Billings.
When a storm hits Gallatin County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
If water is already inside a property in Big Sky, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
