Hennepin County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Plymouth winter roof services, crews handle commercial 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.
Commercial Ice Dam Removal in Plymouth: How The Work Runs
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.
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.
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.
Access control, hatches and escorts
Getting onto a commercial roof is a procedure: keys or fobs, a hatch that may be padlocked, a ladder in a locked plant room, sometimes a site induction and an escort for the duration.
Sorting that out with the property manager in advance is the difference between a crew starting at seven and a crew waiting in the parking lot until nine. Where a tenant controls the only access, that conversation happens before the dispatch rather than on the roof.
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.

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 commercial ice dams pages: Maple Grove, Golden Valley, Hopkins, Minnetonka, Brooklyn Park, St. Louis Park.
During a cold snap Plymouth gets worked alongside the neighboring Hennepin County towns on the same route, with active interior leaks moved to the front of the list.
Most jobs do not stop at one service. Commercial Ice Dams in Plymouth often runs alongside commercial roof snow removal in Plymouth, and both get written into one scope rather than billed as separate visits.
