Homeowners across Brown County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete De Pere winter roof services, crews handle commercial ice dam removal across Brown County.
Why De Pere Roofs Dam Up: Lake-Effect Load and Freeze-Thaw
Lake-effect snow arrives in bands rather than fronts, which is why De Pere can take a foot overnight while a town twenty miles inland takes two inches. It falls wet, it compacts fast, and it does not blow off.

The damage comes on the thaw. Warm air leaking into the attic melts the underside of that pack, the meltwater runs to an eave that is still well below freezing, and it sets. Repeat that four or five times in a January and the ridge of ice at the gutter line stops being cosmetic.
Ice-barrier practice in Brown County
Lake-belt jurisdictions in Wisconsin 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 De Pere: How The Work Runs
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.
Roof warranties and who is allowed up there
Most commercial membranes carry a manufacturer's warranty with conditions about who may work on the roof and what methods are permitted. Snow removal is generally fine; mechanical ice removal very often is not, and the wrong contractor with the wrong tool can void cover worth considerably more than the clearing.
The warranty gets read before the roof is walked, and the method used is one the document permits.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a De Pere unit, there is usually standing water up there.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial De Pere call.
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.

Where We Dispatch Around De Pere
Crews working De Pere cover the adjoining communities on the same route — Wrightstown, Oneida, Greenleaf, Freedom and Seymour — so a storm week usually means one truck handling several addresses in Brown County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Green Bay, Appleton, Neenah, Manitowoc, Oshkosh, Fond du Lac.
Crews cover De Pere and the surrounding Brown County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Commercial Ice Dams in De Pere often runs alongside commercial roof snow removal in De Pere, and both get written into one scope rather than billed as separate visits.
