Most Janesville homeowners find out about an ice dam from the inside — a damp patch on a bedroom ceiling, or water tracking down the inside of a window frame. As part of our complete Janesville winter roof services, crews handle roof shoveling across Rock County.
Why Janesville Roofs Dam Up: Lake-Effect Load and Freeze-Thaw
What makes Rock 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.

Each band is followed by a clearance and a cold night, and that is the cycle doing the damage. Meltwater released during the day sets at the eave after dark, and the ridge at the gutter line gains a layer every time.
Ice-barrier practice in Rock County
Ice-barrier membrane at the eaves is standard practice across the lake-effect counties, and most Wisconsin jurisdictions enforce it on re-roofs. If your roof predates that, the eave has nothing under the shingles holding water out.
Roof Shoveling in Janesville: How The Work Runs
Anchors, rope and why this is not a DIY job
Every crew member on a pitched roof is tied to a rated anchor. On ice over shingle, footing is unreliable in a way that is hard to appreciate from the ground. Ceiling Sagging or Bulging After Snow.
Roof falls are the most common serious winter injury in this trade and they happen to people who have done it for years. A Janesville homeowner in work boots on a January roof is taking a risk out of all proportion to the money saved.
Where hand clearing is the only option
A roof rake reaches the first several feet from the edge and nothing beyond it. Dead valleys between roof planes, the pockets behind dormers and chimneys, low-slope and flat sections, and upper roofs on anything over a story and a half all need someone on the roof with a shovel.
Those are also the places snow collects deepest, because wind deposits it there and nothing sheds it. A Janesville roof can look mostly clear from the street and still be carrying two feet of drifted pack in the valleys.
Partial scopes are normal
Plenty of calls are one dead valley, the pocket behind a chimney, or the flat section over an addition. That is a legitimate job and it gets priced as one.
There is no minimum and no pressure to clear a whole Janesville roof that does not need clearing.
How crews work without wrecking the roof
Plastic-bladed shovels only, never steel. Snow is cut and lifted in layers rather than scraped, and a cushion layer stays on the surface at all times so the blade never contacts shingle, membrane or seam. Discharge is aimed away from walkways, decks, shrubs and mechanical units.
Everyone on the roof is harnessed to a rated anchor. On an icy pitch that is not a formality — it is the whole reason this is not a homeowner job.
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.
Scheduling in Janesville 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.
