Homeowners across Walla Walla County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Walla Walla winter roof services, crews handle commercial ice dam removal across Walla Walla County.
Why Walla Walla Roofs Dam on Days It Never Thaws
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.

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 Walla Walla is clear while the other carries a wall of ice.
Ice-barrier practice in Walla Walla County
Mountain jurisdictions across Walla Walla 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.
Commercial Ice Dam Removal in Walla Walla: How The Work Runs
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Walla Walla building that is a sign the roof is holding standing water somewhere above a frozen drain, and the load is being carried rather than shed.
Scuppers are checked first for exactly that reason, and a dry scupper above a wet roof is as informative as a running one.
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Walla Walla unit, there is usually standing water up there.
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
