Homeowners across Nez Perce County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Lewiston winter roof services, crews handle ice dam insurance claims across Nez Perce County.
Why Lewiston Roofs Dam on Days It Never Thaws
At Lewiston'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 Nez Perce 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 Nez Perce County
Mountain jurisdictions across Nez Perce 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.
Ice Dam Insurance Claims in Lewiston: How The Work Runs
The roof on the same claim
Ice dams can damage the roof itself: shingles lifted or cracked by ice, seal strips broken, underlayment and decking soaked and softened along the eave. Where that damage came from the storm event, it belongs on the same claim as the interior. Does Insurance Pay for Ice Dam Water Damage?.
It does not cover a roof that was simply old. Photographs of the deck from the attic side, the shingles at the eave and the extent of the wet decking are what separate storm damage from wear.
Why the time stamp on the photographs matters
An adjuster arriving in April is looking at a dry ceiling and a clear roof, and is being asked to accept an account of something that happened in January. Dated photographs taken while the ice was on the roof and the water was running are what turn that account into evidence.
Crews photograph on arrival, during the work and on completion, with timestamps intact. It costs nothing at the time and it is routinely the difference between a paid claim and a contested one.
Why the scope gets written in Xactimate line items
Most carriers estimate in Xactimate. A scope that already speaks that language can be compared line for line instead of translated, and translation is where hours get cut.
It does not guarantee the number. It removes one of the common reasons a reasonable number gets reduced.
What a carrier is actually looking for
A claim turns on proving sudden, accidental water intrusion rather than a maintenance failure the homeowner let develop. In practice that means dated photographs of the dam, the entry points and the interior damage, taken while the event is live — not reconstructed in March from memory.
Crews photograph as they work for exactly this reason. Timestamped images of the ice before removal, the water path, the affected interior and the dried-out result form the spine of a claim that survives review.
Scopes in the format adjusters use
Scopes get written in Xactimate line items, with the mitigation work priced and described the way a carrier's own estimating software describes it. An adjuster comparing like to like approves faster than one translating a hand-written invoice into their system.
Where the policy allows direct billing, carriers are billed directly, so the out-of-pocket conversation is smaller from the start.
