By the time a roof in Cottage Grove has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Cottage Grove winter roof services, crews handle roof shoveling 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.
Roof Shoveling in Cottage Grove: How The Work Runs
Timing a clear against the forecast
Clearing a roof the day before eight more inches arrive is money spent twice. Clearing it the day before a thaw, or ahead of a rain-on-snow event, is money that prevents a claim. Ceiling Sagging or Bulging After Snow.
Scheduling in Cottage Grove is built around the forecast rather than the order calls came in, and a job gets moved - with a reason - when the weather makes a different day obviously better.
Flat and low-slope roofs shed nothing
A pitched roof loses some of its load on its own. A flat or low-slope roof does not: whatever falls stays, settles, and gets heavier as it absorbs the next melt.
On Cottage Grove properties with a flat section — a garage, an addition, a porch roof, a whole commercial deck — hand clearing is not optional maintenance, it is the only way the load comes off.
Working around what is up there
Rooftop units, exhaust fans, conduit runs, gas lines, solar racking, skylights and safety railing all have to be cleared around rather than over. The drift shadow behind a unit is usually the deepest snow on the roof.
Skylights in particular get flagged and worked around deliberately — a shovel through cold glass is a bad afternoon for everyone.
Cutting in layers rather than scraping
Crews cut the pack into blocks and lift them, leaving a cushion layer behind. The blade never touches the roof surface. That is the whole technique and it is why a shovelled roof looks untouched afterwards.
Scraping to bare membrane or bare shingle is what damages a roof, and it is what a well-meaning homeowner with a steel shovel does on the first pass.
Clearing to let the drains work
On anything flat, the job is not finished when the snow is off. Drains, scuppers and overflow outlets have to be opened so the melt that follows has somewhere to go.
A cleared Cottage Grove deck with blocked drains just ponds and refreezes, and ponded water on a membrane finds seams.

Crews working Cottage Grove cover the adjoining communities on the same route — Saint Paul Park, Newport, Afton, South Saint Paul and Vermillion — so a storm week usually means one truck handling several addresses in Washington County rather than separate trips.
Nearest hub towns with their own roof shoveling pages: Inver Grove Heights, Woodbury, Hastings, Maplewood, Oakdale, Eagan.
Coverage runs across Cottage Grove and the nearby towns all winter, and capacity is surged into whichever Minnesota market the storm actually hits.
Most jobs do not stop at one service. Roof Shoveling in Cottage Grove often runs alongside roof snow removal in Cottage Grove, and both get written into one scope rather than billed as separate visits.
