Most Tigard homeowners find out about an ice dam from the inside — a damp patch on a bedroom ceiling, or water tracking down the inside of a window frame. As part of our complete Tigard winter roof services, crews handle roof snow removal across Washington County.
Elevation, Aspect and Ice: The Washington County Pattern
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.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Tigard 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 Washington County
Design snow loads in Washington County are among the highest anywhere, and the membrane and retention requirements that go with them are not formalities. On an older Tigard cabin or chalet neither may be present.
Roof Snow Removal in Tigard: How The Work Runs
Rain on top of snow
A warm rain onto a deep pack is the loading case that puts roofs on the news. The snow absorbs the rain instead of shedding it, the drains and gutters are still frozen, and the load can climb sharply within hours while the depth barely changes. Ceiling Sagging or Bulging After Snow.
When that forecast appears over Washington the priority order changes: large flat spans and anything already carrying a deep pack get cleared ahead of the line, before the rain rather than after it.
Clearing the eaves is what matters
The first three to six feet above the gutter line is where dams build, because that strip of roof sits past the heated part of the house. Taking the snow off that band removes the meltwater supply before the next thaw-freeze cycle can turn it into ice.
Crews work from the ground with extended rakes wherever the pitch and height allow, and from the roof with harnesses and anchors when they do not. A cushion layer of snow is always left behind on the surface, because a rake run hard against bare shingle does its own damage.
How much of the roof actually needs clearing
Rarely all of it. The band that matters is the lower three to six feet above the gutter, because that is the strip sitting past the heated envelope where meltwater refreezes.
On a roof in Tigard with no load concern, clearing that band and the valleys is usually the whole job. Scraping the full plane costs more, takes longer, and buys very little extra.
Rake from the ground or crew on the roof
Ground work is safer, cheaper and enough for most single-story and story-and-a-half Tigard homes. The limit is reach: a rake handles the first several feet and nothing past it.
Above that, or where the pitch makes a rake useless, somebody goes up harnessed. The call is made on arrival and the rate reflects which it turned out to be.
Wet snow, dry snow and what the weight actually is
Depth tells you very little on its own. Light powder runs around seven pounds per cubic foot; old settled snow two or three times that; the saturated layer sitting at the bottom of a pack after a thaw can approach the weight of standing water. Two roofs in Tigard under the same twenty inches can be carrying loads that differ by a factor of four.
Crews take a core and weigh it rather than guessing from the ruler, because that measurement is what decides whether a roof is near its limit or nowhere close.

Where We Dispatch Around Tigard
Crews working Tigard cover the adjoining communities on the same route — Tualatin, Marylhurst, Sherwood, West Linn and Wilsonville — so a storm week usually means one truck handling several addresses in Washington County rather than separate trips.
Nearest hub towns with their own roof snow removal pages: Beaverton, Lake Oswego, Portland, Hillsboro, Oregon City, Gresham.
Scheduling for Tigard 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. Roof Snow Removal in Tigard often runs alongside ice dam removal in Tigard, and both get written into one scope rather than billed as separate visits.
