Homeowners across Walla Walla County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Walla Walla winter roof services, crews handle commercial roof snow removal across Walla Walla County.
Why Walla Walla Roofs Dam on Days It Never Thaws
Mountain ice dams are a solar problem more than a temperature one. The sun works the pack from above while the air stays cold, so meltwater is produced and refrozen within the same afternoon.
Aspect decides everything here. The sunny plane sheds water that the shaded plane and the shaded eave then lock up, so one side of a roof in Walla Walla is clear while the other carries a wall of ice.
Ice-barrier practice in Walla Walla County
Mountain jurisdictions across Walla Walla County generally require ice-barrier membrane well up the roof plane, not just the first course, along with snow retention on metal roofs above entries and walkways.
Commercial Roof Snow Removal in Walla Walla: How The Work Runs
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. Ceiling Sagging or Bulging After Snow.
Where the drawings have been lost - common on older Walla Walla 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.
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.
Why large decks carry the most risk
A long-span steel or open-web joist roof has the least margin exactly where the drift is deepest — mid-span. Snow does not settle evenly either: it piles against parapets, behind rooftop units, in the lee of higher adjoining roofs, and in valleys between bays. The average depth across the roof is not the number that matters.
Crews survey depth and density at the drift points rather than the middle of the field, and calculate the working load from that against the structure's design capacity.
Reduction to a threshold, not a bare deck
The goal is bringing the load under the structure's capacity safely, with a cushion layer left on the membrane throughout.
Scraping a commercial Walla Walla roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
What the documentation covers
Depth and density readings, calculated load, dated photographs and a written condition report per visit.
Preventing an imminent failure is treated as loss mitigation by most carriers, and that record is what supports the position if it is ever tested.

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