Why Ketchikan Roofs Dam Up: Altitude Sun on a Deep Pack
At Ketchikan'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.

Volume is the other factor. A Ketchikan Gateway County roof carrying several feet of pack has an enormous reservoir above an overhang that never sees direct sun, and the supply does not run out until spring.
Ice-barrier practice in Ketchikan Gateway County
Mountain jurisdictions across Ketchikan Gateway County generally require ice-barrier membrane well up the roof plane, not just the first course, along with snow retention on metal roofs above entries and walkways.
How a Ketchikan Steam Call Runs, Start to Finish
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.
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.
Steep, high and awkward Ketchikan 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 Ketchikan needs a longer setup, it is said on the phone rather than discovered at the end of the invoice.
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 Ketchikan the following week.
