Homeowners across Clackamas County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Lake Oswego winter roof services, crews handle ice dam removal across Clackamas County.
Why Lake Oswego Roofs Dam Up: Altitude Sun on a Deep Pack
The pack at this elevation is deep enough to act as its own insulation, which means the surface melts under sun while the base stays locked. Water released at the top has to travel through and under all of it.

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 Clackamas County
Design snow loads up here are among the highest in the country, and the membrane and retention details that come with them are not paperwork. On an older Lake Oswego cabin neither is likely to be present.
Ice Dam Removal in Lake Oswego: How The Work Runs
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 Lake Oswego home. Water Stain on the Ceiling in Winter.
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.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.
What happens after the ice is off
Once the eave is clear and water is draining, the crew walks the interior with you where there is visible damage and says plainly whether it needs drying. Wet insulation and a damp ceiling cavity do not resolve themselves in a cold Lake Oswego February.
If it does, that is a separate scope and it gets written separately — nobody is upsold a dryout on the strength of one damp patch.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Lake Oswego clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
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.

Lake Oswego Coverage and the Adjoining Communities
Crews working Lake Oswego cover the adjoining communities on the same route — Marylhurst, West Linn, Tualatin, Gladstone and Happy Valley — so a storm week usually means one truck handling several addresses in Clackamas County rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Tigard, Portland, Beaverton, Oregon City, Hillsboro, Gresham.
Crews cover Lake Oswego and the surrounding Clackamas County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Ice Dam Removal in Lake Oswego often runs alongside water mitigation & dryout in Lake Oswego, and both get written into one scope rather than billed as separate visits.
