Why Valdez Roofs Dam Up: Altitude Sun on a Deep Pack
Mountain ice dams are a solar problem more than a temperature one. The sun works the pack from above while the air stays cold, so meltwater is produced and refrozen within the same afternoon.

That is why mountain roofs dam up on clear, cold weeks that look harmless. South and west faces melt, north-facing eaves and shaded valleys hold the ice, and the pack above keeps feeding it.
Ice-barrier practice in Valdez Cordova County
High-country Alaska codes typically call for extended ice barrier and, on metal roofing, snow guards above any door, walkway or parking area. Both exist because of what comes off these roofs.
The Valdez Dispatch Process, Step by Step
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.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.
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 Valdez the following week.
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.
