Sun on Cold Snow: The Crested Butte Pattern
Thin air at altitude means intense direct sun even in deep cold. A Crested Butte 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.
Depth makes it worse. A Gunnison County roof can carry several feet of pack, and all of that is a reservoir sitting above an eave that never sees sun.
Ice-barrier practice in Gunnison 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 Crested Butte cabin neither is likely to be present.
What a Crew Does on a Crested Butte 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.
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 Crested Butte 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.
Steep, high and awkward Crested Butte 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 Crested Butte needs a longer setup, it is said on the phone rather than discovered at the end of the invoice.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in Crested Butte with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.

Crested Butte Coverage and the Adjoining Communities
Crews working Crested Butte cover the surrounding Gunnison 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: Aspen, Glenwood Springs, Montrose, Vail, Frisco, Breckenridge.
When a storm hits Gunnison 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 Crested Butte, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
