Why Yakima Roofs Dam on Days It Never Thaws
Altitude makes the sun stronger and the air colder at the same time. A roof in Yakima can be producing meltwater on its south face at midday while the thermometer reads well below freezing.
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 Yakima County
Mountain jurisdictions across Yakima 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.
What a Crew Does on a Yakima Roof
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.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in Yakima with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
What the crew does on arrival
Before anything is touched, the crew walks the eaves, valleys and gutter line and photographs every dam and every point where water is tracking inside. You get shown what they found. Then the dam comes off in sections, starting wherever water is actively backing up, so drainage opens early rather than at the end.
Downspouts and gutter troughs get cleared in the same visit where they are frozen, because a dam removed above a solid block of ice in the gutter just reforms in the next cold night.
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 Yakima 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.

Yakima County Coverage From Yakima
Crews working Yakima cover the adjoining communities on the same route — Selah, Moxee, Parker, Wapato and Cowiche — so a storm week usually means one truck handling several addresses in Yakima County rather than separate trips.
Nearest hub towns with their own crew pages: Ellensburg, Cle Elum, Wenatchee, Richland, Moses Lake, Kennewick.
Scheduling for Yakima tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
If water is already inside a property in Yakima, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
