Homeowners across Hennepin County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Plymouth winter roof services, crews handle ice dam removal across Hennepin County.
Plymouth Ice Dams: What Lake-Effect Snow Does to an Eave
What makes Hennepin County roofs dam is not the seasonal total, it is how the snow arrives. Bands dump a heavy, saturated pack in hours, and that pack becomes a water reservoir sitting on a heated surface.
What turns that pack into a dam is the house underneath it. Warm air finds its way into the attic, the underside of the snow melts, and the water travels to an overhang that has no heated space below it. There it stops.
Ice-barrier practice in Hennepin County
Ice-barrier membrane at the eaves is standard practice across the lake-effect counties, and most Minnesota jurisdictions enforce it on re-roofs. If your roof predates that, the eave has nothing under the shingles holding water out.
Ice Dam Removal in Plymouth: How The Work Runs
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath. Water Stain on the Ceiling in Winter.
It is a stopgap at best. On a roof in Plymouth with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
If water already got inside
Taking the ice off stops new water. It does nothing about what is already in the insulation, the ceiling and the walls of a Plymouth home.
The same company handles the rest: water mitigation and dryout, mold remediation where the water has led to growth, the interior repair, and the roof where the dam damaged it, all documented on one insurance claim.
Access, ladders and what the crew needs on site
Steam equipment needs somewhere to park within hose reach, and ladders need footing that is not a buried flower bed or a sheet of ice. Clearing a path to the affected eave, moving vehicles off the driveway and unlocking a side gate takes ten minutes and saves considerably more than that on the clock.
Where the only access is through a neighbor's property, that conversation is worth having before the crew is in the street rather than while it waits.
What gets photographed, and why it matters later
Before the lance comes out, the crew shoots the dam from the ground and from the roof, the icicle line, any staining visible inside, and the specific courses where water is tracking under the shingles. Timestamps are on every frame.
That record is the whole case if a claim follows. An adjuster arriving in March sees a dry roof and a stained ceiling; the photographs are what connect the two, and they are what a maintenance-exclusion denial runs into.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.

Plymouth Coverage and the Adjoining Communities
Crews working Plymouth cover the adjoining communities on the same route — Wayzata, Navarre, Long Lake, Osseo and Crystal Bay — so a storm week usually means one truck handling several addresses in Hennepin County rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Maple Grove, Golden Valley, Hopkins, Minnetonka, Brooklyn Park, St. Louis Park.
Crews cover Plymouth and the surrounding Hennepin 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. Ice Dam Removal in Plymouth often runs alongside water mitigation & dryout in Plymouth, and both get written into one scope rather than billed as separate visits.
Active leak right now? Our 24/7 Plymouth steam ice dam removal crews are dispatched first during a freeze event. Call (888) 561-9664.
