Sun on Cold Snow: The Durango Pattern
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 which eaves suffer. A sunny plane sheds water across a roof in Durango 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 La Plata County
Design snow loads in La Plata County are among the highest anywhere, and the membrane and retention requirements that go with them are not formalities. On an older Durango cabin or chalet neither may be present.
How a Durango Steam Call Runs, Start to Finish
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 Durango 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.
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.

Where We Dispatch Around Durango
Crews working Durango cover the adjoining communities on the same route — Bayfield — so a storm week usually means one truck handling several addresses in La Plata County rather than separate trips.
Nearest hub towns with their own crew pages: Telluride, Montrose, Crested Butte, Grand Junction, Aspen, Glenwood Springs.
Durango sits inside the regular Colorado service area, so a crew is usually scheduled the same day or the following morning.
