Why Ketchum Roofs Dam on Days It Never Thaws
At Ketchum'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.

Depth makes it worse. A Blaine 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 Blaine County
Snow retention above doors, walkways and parking is a requirement in most Blaine County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
How We Work a Ketchum 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 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 Ketchum 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.
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 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.

Blaine County Coverage From Ketchum
Crews working Ketchum cover the adjoining communities on the same route — Hailey — so a storm week usually means one truck handling several addresses in Blaine County rather than separate trips.
Nearest hub towns with their own crew pages: Sun Valley, Mountain Home, Twin Falls, Boise, Eagle, Meridian.
When a storm hits Blaine County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Water through a ceiling in Ketchum is a same-day call, not a next-week one. (888) 561-9664 goes straight to dispatch.
