Rock County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Janesville winter roof services, crews handle commercial ice dam removal 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.
Commercial Ice Dam Removal in Janesville: How The Work Runs
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.
Membrane-safe means something specific
EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.
Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.
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 Janesville building that distinction shows up as a tenant ceiling two floors down.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Janesville building that is a sign the roof is holding standing water somewhere above a frozen drain, and the load is being carried rather than shed.
Scuppers are checked first for exactly that reason, and a dry scupper above a wet roof is as informative as a running one.
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.
