Ice dams are not a Spokane Valley problem so much as a Washington one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Spokane Valley winter roof services, crews handle commercial roof snow removal across Spokane County.
Sun on Cold Snow: The Spokane Valley Pattern
At Spokane Valley'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.
Volume is the other factor. A Spokane County roof carrying several feet of pack has an enormous reservoir above an overhang that never sees direct sun, and the supply does not run out until spring.
Ice-barrier practice in Spokane County
Snow retention above doors, walkways and parking is a requirement in most Spokane County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
Commercial Roof Snow Removal in Spokane Valley: How The Work Runs
Mid-span is where the margin runs out
Long-span steel and open-web joist roofs carry least where the drift is deepest. The average depth across the field is not the number that matters; the depth over the longest unsupported span is. Ceiling Sagging or Bulging After Snow.
That is where crews measure on a Spokane Valley building, and it is why two roofs with the same snowfall can be in very different trouble.
Reading the design load off the drawings
Where structural drawings exist they state the design ground snow load and the roof's own capacity, and that number turns the whole question from opinion into arithmetic. Measured depth and density against design capacity gives a percentage rather than an argument.
Where the drawings have been lost - common on older Spokane Valley stock - the conservative assumption is the code minimum of the era the building went up, which is usually well below what a modern roof would be built to.
Sequencing so the load comes off evenly
Stripping one bay to the deck while the next still carries two feet creates exactly the unbalanced condition that overloads a member. Structures object less to a lot of weight spread evenly than to a moderate weight concentrated on one side.
Crews work in passes across the whole span, reducing everywhere before going deeper anywhere, and the sequence is set before anybody starts rather than left to whoever gets up there first.
Reduction, not bare deck
The goal is to bring the load under threshold safely, not to scrape a roof in Spokane Valley clean. Clearing is balanced across the deck so load is not shifted onto one bay, drains and scuppers are opened so melt has an exit, and a cushion layer always stays on the membrane.
Where the figures call for it, crews bring in crane-assisted picks instead of adding bodies to a roof that is already carrying too much.
Ponding after the clear
Taking the snow off a flat roof with frozen drains leaves meltwater with nowhere to go, and water that ponds and refreezes puts load back on a deck that was just relieved.
So drains and overflows are opened as part of the clear rather than afterwards, and the roof is left draining. A clear that stops at the snow is half a job.

Where We Dispatch Around Spokane Valley
Crews working Spokane Valley cover the adjoining communities on the same route — Veradale, Greenacres, Otis Orchards, Liberty Lake and Mead — so a storm week usually means one truck handling several addresses in Spokane County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Spokane, Pullman, Moses Lake, Walla Walla, Pasco, Kennewick.
Crews cover Spokane Valley and the surrounding Spokane 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. Commercial Snow in Spokane Valley often runs alongside crane-assisted snow removal in Spokane Valley, and both get written into one scope rather than billed as separate visits.
