Winter in Pullman does not need a record storm to put water inside a house. It needs a roof with snow on it, an attic leaking heat, and one cold night. As part of our complete Pullman winter roof services, crews handle commercial ice dam removal across Whitman County.
Why Pullman Roofs Dam on Days It Never Thaws
At Pullman'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 Whitman 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 Whitman County
Design snow loads in Whitman County are among the highest anywhere, and the membrane and retention requirements that go with them are not formalities. On an older Pullman cabin or chalet neither may be present.
Commercial Ice Dam Removal in Pullman: How The Work Runs
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
Scheduling around tenants
Noise, access, parking and the hours a Pullman business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Pullman unit, there is usually standing water up there.
Membrane-safe means something specific
EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.
Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.

Where We Dispatch Around Pullman
Crews working Pullman cover the adjoining communities on the same route — Albion, Colton, Palouse and Colfax — so a storm week usually means one truck handling several addresses in Whitman County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Spokane Valley, Spokane, Walla Walla, Pasco, Kennewick, Moses Lake.
Pullman sits inside the regular Washington service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Commercial Ice Dams in Pullman often runs alongside commercial roof snow removal in Pullman, and both get written into one scope rather than billed as separate visits.
