The ice along a roof in Yakimaline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Yakima winter roof services, crews handle commercial roof snow removal across Yakima County.
Why Yakima Roofs Dam on Days It Never Thaws
Altitude makes the sun stronger and the air colder at the same time. A roof in Yakima can be producing meltwater on its south face at midday while the thermometer reads well below freezing.

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 Yakima County
Mountain jurisdictions across Yakima 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 Yakima: How The Work Runs
Fall protection on a deck with no anchors
Most commercial roofs have no permanent anchor points and a parapet too low to count as a guard. Working near an unprotected edge legally requires a system, and improvising one is where people get hurt. Ceiling Sagging or Bulging After Snow.
Crews bring mobile anchors, warning lines and whatever the layout actually needs. Where the roof cannot be worked safely at all, that gets reported to the Yakima property manager as a finding, because it will be just as true during the next storm.
Unbalanced loading is the real hazard
Snow does not settle evenly on a large deck. It piles against parapets, behind rooftop units, in the lee of a higher adjoining roof and in the valleys between bays.
Clearing has to be balanced for the same reason. Taking it all off one bay and none off the next shifts the load rather than removing it.
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 Yakima roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.

Yakima County Coverage From Yakima
Crews working Yakima cover the adjoining communities on the same route — Selah, Moxee, Parker, Wapato and Cowiche — so a storm week usually means one truck handling several addresses in Yakima County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Ellensburg, Cle Elum, Wenatchee, Richland, Moses Lake, Kennewick.
Scheduling for Yakima 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. Commercial Snow in Yakima often runs alongside crane-assisted snow removal in Yakima, and both get written into one scope rather than billed as separate visits.
