Ice dams are not a Green Bay problem so much as a Wisconsin one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Green Bay winter roof services, crews handle water mitigation & dryout across Brown County.
The Brown County Pattern: Heavy Bands, Fast Thaws
Roofs in Green Bay 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.
Melting happens from underneath, not from the sun. Attic heat releases water under the pack, it runs to the overhang where there is no heated space below, and it freezes. That is the engine, and in Green Bay it runs most of the winter.

The relevant detail is how far up the roof the membrane runs — it has to reach past the interior wall line, not just cover the first course. On older Green Bay roofs it frequently does neither.
Water Mitigation & Dryout in Green Bay: How The Work Runs
Why wet insulation comes out rather than dries
Saturated cellulose and fiberglass hold water against framing and sheathing for weeks, and in a cold attic there is no air movement to carry it off. It also stops insulating, which warms the deck and feeds the next dam. Wet Insulation in the Attic.
So it comes out. On an attic in Green Bay that is usually the single biggest step toward the structure actually drying.
Why a cold attic will not dry itself
Drying is evaporation, and evaporation needs warmth and air movement. A Green Bay attic in February has neither. Wet insulation and damp sheathing sit at near-freezing with no meaningful vapor drive, which is why a leak that stops in January can still be wet in March.
Equipment supplies what the season does not. Without it the structure is not drying slowly - in a cold cavity it is very largely not drying at all.
The sequence
Standing water is extracted first. Saturated insulation comes out, because it cannot be dried in place and it is holding moisture against everything it touches. Containment goes up where tear-out is needed, with HEPA scrubbers running inside it. Dehumidifiers and air movers are placed to the room's volume and load rather than scattered around.
Then the readings get taken daily until they hit standard. In a Green Bay winter, with cold cavities and low ambient humidity outside, that typically takes longer than people expect.
What happens to flooring
Hardwood cups as it absorbs and may flatten out on its own once the subfloor is dry, so it is given the chance before anyone talks about replacement. Laminate and engineered board usually do not recover.
Carpet and pad are a judgment call on how long they were wet and what the water passed through on the way down.
Containment before tear-out
Where drywall or insulation has to come out, barriers go up and HEPA scrubbers run inside them. That keeps the dust and whatever is growing in the wet material out of the rest of the house.
It also keeps the job to one room rather than the whole floor, which on an occupied Green Bay home is the difference between staying and moving out.

Neighborhoods and Towns We Reach From Green Bay
Crews working Green Bay cover the adjoining communities on the same route — Oneida, Suamico, New Franken, Wrightstown and Denmark — so a storm week usually means one truck handling several addresses in Brown County rather than separate trips.
Nearest hub towns with their own water mitigation pages: De Pere, Appleton, Neenah, Manitowoc, Oshkosh, Sheboygan.
Coverage runs across Green Bay and the nearby towns all winter, and capacity is surged into whichever Wisconsin market the storm actually hits.
Most jobs do not stop at one service. Water Mitigation in Green Bay often runs alongside ice dam removal in Green Bay, and both get written into one scope rather than billed as separate visits.
