Why Madison Roofs Dam Up: Lake-Effect Load and Freeze-Thaw
Lake-effect snow arrives in bands rather than fronts, which is why Madison 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.
What turns that pack into a dam is the house underneath it. Warm air finds its way into the attic, the underside of the snow melts, and the water travels to an overhang that has no heated space below it. There it stops.
Ice-barrier practice in Dane County
What matters on a Madison roof is not whether ice barrier exists but how far up it runs. Water backed up behind a foot of ice travels much further than the first course, and a membrane that stops short is a membrane that stops working.
How We Work a Madison Ice Dam
Nothing gets touched until the roof has been walked and photographed. The crew finds every dam, locates where water is getting in, shows you, and gives you the crew-hour rate and a time estimate before the equipment comes off the truck.
Removal then works from the worst point outward, so water starts draining early rather than at the end. Gutters and downspouts frozen solid get steamed through in the same visit — leaving them means the eave dams again within days.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.
Access, ladders and what the crew needs on site
Steam equipment needs somewhere to park within hose reach, and ladders need footing that is not a buried flower bed or a sheet of ice. Clearing a path to the affected eave, moving vehicles off the driveway and unlocking a side gate takes ten minutes and saves considerably more than that on the clock.
Where the only access is through a neighbor's property, that conversation is worth having before the crew is in the street rather than while it waits.
What gets photographed, and why it matters later
Before the lance comes out, the crew shoots the dam from the ground and from the roof, the icicle line, any staining visible inside, and the specific courses where water is tracking under the shingles. Timestamps are on every frame.
That record is the whole case if a claim follows. An adjuster arriving in March sees a dry roof and a stained ceiling; the photographs are what connect the two, and they are what a maintenance-exclusion denial runs into.

Dane County Coverage From Madison
Crews working Madison cover the adjoining communities on the same route — Mc Farland, Middleton, Waunakee, Cottage Grove and Oregon — so a storm week usually means one truck handling several addresses in Dane County rather than separate trips.
Nearest hub towns with their own crew pages: Fitchburg, Sun Prairie, Janesville, Watertown, Beloit, Waukesha.
During a cold snap Madison gets worked alongside the neighboring Dane County towns on the same route, with active interior leaks moved to the front of the list.
Water through a ceiling in Madison is a same-day call, not a next-week one. (888) 561-9664 goes straight to dispatch.
