The ice along a roof in Greshamline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Gresham winter roof services, crews handle ice dam removal across Multnomah County.
Sun on Cold Snow: The Gresham Pattern
At Gresham'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.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Gresham to a shaded eave that has not been above freezing for weeks, and that is where the ice builds into a wall.
Ice-barrier practice in Multnomah County
High-country Oregon 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.
Ice Dam Removal in Gresham: How The Work Runs
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. Water Stain on the Ceiling in Winter.
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 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 Gresham with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
If water already got inside
Taking the ice off stops new water. It does nothing about what is already in the insulation, the ceiling and the walls of a Gresham home.
The same company handles the rest: water mitigation and dryout, mold remediation where the water has led to growth, the interior repair, and the roof where the dam damaged it, all documented on one insurance claim.
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.
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 Gresham 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.

Scheduling for Gresham tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Ice Dam Removal in Gresham often runs alongside water mitigation & dryout in Gresham, and both get written into one scope rather than billed as separate visits.
