The Washtenaw County Trap: Modest Snow, Constant Cycling
Ann Arbor does not need a blizzard to get an ice dam. A few inches that melts by afternoon and refreezes overnight builds one just as effectively, and it does it over and over through the season.
Because the winters read as mild, the building stock is not built for ice. Attic insulation is thinner, eave details are less considered, and ice barrier is more often absent than present on a roof in Ann Arbor.
Ice-barrier practice in Washtenaw County
The residential code Michigan follows calls for eave ice barrier on new work. Enforcement in Washtenaw County is real but recent, so the age of the roof is what decides whether it is there.
How We Work an Ann Arbor Ice Dam
Crews walk the eaves, valleys and gutter line first and photograph every dam and every point where water is tracking inside, before touching anything. You get shown what they found and quoted the crew-hour rate before work starts.
Then the ice comes off with low-pressure steam, starting wherever water is actively backing up so drainage opens early. Frozen gutters and downspouts are cleared in the same visit, because a cleared eave above a solid block of ice in the gutter dams again on the next cold night.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in Ann Arbor the following week.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Ann Arbor clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Ann Arbor house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.

Ann Arbor Coverage and the Adjoining Communities
Crews working Ann Arbor cover the adjoining communities on the same route — Saline, Dexter, Bridgewater, Whitmore Lake and Hamburg — so a storm week usually means one truck handling several addresses in Washtenaw County rather than separate trips.
Nearest hub towns with their own crew pages: Ypsilanti, Novi, Westland, Livonia, Farmington Hills, Taylor.
When a storm hits Washtenaw County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Water through a ceiling in Ann Arbor is a same-day call, not a next-week one. (888) 561-9664 goes straight to dispatch.
