A Minnetonka roof can look fine from the driveway and still be backing water under the shingles at the eave, where nobody can see it. As part of our complete Minnetonka winter roof services, crews handle commercial ice dam removal across Hennepin County.
What the Lake Does to a Roof in Minnetonka
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
Lake-belt jurisdictions in Minnesota have enforced eave membrane on re-roof permits for a long time. The roofs that leak are, almost without exception, the ones that have not been touched since before that.
Commercial Ice Dam Removal in Minnetonka: How The Work Runs
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.
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.
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.
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 Minnetonka unit, there is usually standing water up there.

Minnetonka Coverage and the Adjoining Communities
Crews working Minnetonka cover the adjoining communities on the same route — Wayzata, Navarre, Excelsior, Minnetonka Beach 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: Hopkins, Chanhassen, Eden Prairie, St. Louis Park, Edina, Plymouth.
When a storm hits Hennepin County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Commercial Ice Dams in Minnetonka often runs alongside commercial roof snow removal in Minnetonka, and both get written into one scope rather than billed as separate visits.
