Why Green River Roofs Dam on Days It Never Thaws
At Green River's elevation the air can stay below freezing all day while direct sun still melts the top of the snowpack. That meltwater runs down under the pack, reaches a shaded eave, and refreezes — on a day the thermometer never rose above freezing.
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 Green River is clear while the other carries a wall of ice.
Ice-barrier practice in Sweetwater 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 Green River cabin neither is likely to be present.
How We Work a Green River Ice Dam
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in Green River the following week.
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.
What gets photographed, and why it matters later
Before the lance comes out, the crew shoots the dam from the ground and from the roof, the icicle line, any staining visible inside, and the specific courses where water is tracking under the shingles. Timestamps are on every frame.
That record is the whole case if a claim follows. An adjuster arriving in March sees a dry roof and a stained ceiling; the photographs are what connect the two, and they are what a maintenance-exclusion denial runs into.

Green River Coverage and the Adjoining Communities
Crews working Green River cover the surrounding Sweetwater 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: Rock Springs, Evanston, Lander, Riverton, Jackson, Teton Village.
Scheduling for Green River tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Water through a ceiling in Green River is a same-day call, not a next-week one. (888) 561-9664 goes straight to dispatch.
