Ice dams are not a Eugene problem so much as an Oregon one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Eugene winter roof services, crews handle commercial ice dam removal across Lane County.
Eugene Ice Dams: Melting on Days It Never Thaws
Altitude makes the sun stronger and the air colder at the same time. A roof in Eugene can be producing meltwater on its south face at midday while the thermometer reads well below freezing.

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 Eugene is clear while the other carries a wall of ice.
Ice-barrier practice in Lane County
Design snow loads up here are among the highest in the country, and the membrane and retention details that come with them are not paperwork. On an older Eugene cabin neither is likely to be present.
Commercial Ice Dam Removal in Eugene: How The Work Runs
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on a Eugene building that distinction shows up as a tenant ceiling two floors down.
What the board or the owner gets
A condition report with dated photographs, what was found, what was done and what is still a risk — in a form that can go to a board, an owner or a carrier without being rewritten.
For a managed Eugene property that document is usually the reason the spend gets approved without a second conversation.
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.
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
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.

Neighborhoods and Towns We Reach From Eugene
Crews working Eugene cover the adjoining communities on the same route — Thurston, Alvadore, Junction City, Pleasant Hill and Creswell — so a storm week usually means one truck handling several addresses in Lane County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Springfield, Corvallis, Albany, Salem, Keizer, McMinnville.
Crews cover Eugene and the surrounding Lane 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 Ice Dams in Eugene often runs alongside commercial roof snow removal in Eugene, and both get written into one scope rather than billed as separate visits.
