Ice dams are not a Hillsboro problem so much as an Oregon one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Hillsboro winter roof services, crews handle ice dam removal across Washington County.
Hillsboro Ice Dams: Melting on Days It Never Thaws
At Hillsboro'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 Washington 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 Washington County
Snow retention above doors, walkways and parking is a requirement in most Washington County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
Ice Dam Removal in Hillsboro: How The Work Runs
Access, ladders and what the crew needs on site
Steam equipment needs somewhere to park within hose reach, and ladders need footing that is not a buried flower bed or a sheet of ice. Clearing a path to the affected eave, moving vehicles off the driveway and unlocking a side gate takes ten minutes and saves considerably more than that on the clock. Water Stain on the Ceiling in Winter.
Where the only access is through a neighbor's property, that conversation is worth having before the crew is in the street rather than while it waits.
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 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 Hillsboro with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
Why the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.

Washington County Coverage From Hillsboro
Crews working Hillsboro cover the adjoining communities on the same route — Cornelius, North Plains, Forest Grove, Gaston and Sherwood — so a storm week usually means one truck handling several addresses in Washington County rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Beaverton, Tigard, Portland, Lake Oswego, Oregon City, McMinnville.
Hillsboro sits inside the regular Oregon service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Ice Dam Removal in Hillsboro often runs alongside water mitigation & dryout in Hillsboro, and both get written into one scope rather than billed as separate visits.
