Cottage Grove Ice Dams: What Lake-Effect Snow Does to an Eave
Roofs in Cottage Grove are loaded unevenly and quickly. A band sets up, dumps for six hours and moves, and the roof is carrying a dense wet pack it did not have at breakfast. Nothing about that snow wants to slide off.

Then the temperature swings. Lake-effect regions cycle hard either side of freezing, and each cycle moves meltwater down to a cold eave and locks it there. The dam grows by a layer every time, and the water behind it rises with it.
Ice-barrier practice in Washington 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.
How a Cottage Grove Steam Call Runs, Start to Finish
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Cottage Grove, and a postponed start gets explained rather than dressed up.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in Cottage Grove the following week.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Cottage Grove house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.
