Ice dams are not a Cottage Grove problem so much as a Minnesota one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Cottage Grove winter roof services, crews handle commercial ice dam removal across Washington County.
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.
Commercial Ice Dam Removal in Cottage Grove: 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 Cottage Grove building that distinction shows up as a tenant ceiling two floors down.
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.
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.
Built for property managers
One contact, one scheduled window, one invoice coded the way your accounting needs it. Crews work around tenant hours where that matters, and the condition report goes to whoever has to show the board or the owner what was spent and why.
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.
