Homeowners across Washtenaw County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Ann Arbor winter roof services, crews handle heated roof & gutter cables across Washtenaw County.
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.
Heated Roof & Gutter Cables in Ann Arbor: How The Work Runs
Retrofit against installing during a roof replacement
Cable can be added to an existing roof at any time and usually is. If an Ann Arbor roof is being replaced anyway, that is the cheaper moment: clips can go under the courses, the downspout run can be planned properly, and the circuit can be brought to the eave while the fascia is open. Icicles and a Wet Ceiling.
Where a replacement is a year or two out, it is worth saying so before the retrofit is designed, so the layout can be reused rather than scrapped.
Cable is the backstop, not the cure
The underlying cause of an ice dam is heat leaving the house. Air sealing the attic, fixing crushed baffles and topping up insulation addresses that; cable manages what is left.
A Ann Arbor property that gets both rarely needs an emergency call again. One that gets only cable usually needs fewer.
Commercial and multi-family runs
The same cable on a large building becomes a different exercise - several hundred feet of run, multiple circuits, a controller that something has to monitor, and a decision about who gets the alarm when a circuit fails.
Scope, circuit loading and control strategy get worked out with whoever maintains the Ann Arbor building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.
The electrical side
A dedicated GFCI-protected circuit, properly rated terminations and a disconnect somebody can actually reach. Not an extension cord out of a bathroom window, which is what gets found on a surprising number of existing Ann Arbor installs.
Done properly it is an ordinary piece of exterior electrical work and it should look like one.
What heat trace does and does not do
A properly designed system keeps a continuous drainage channel open from the roof surface through the gutter and down the leader to the ground. Meltwater that would have refrozen at the cold eave instead keeps running. It does not melt the snow off your roof, and it will not remove a dam that has already formed — it prevents the dam from establishing in the first place.
That distinction matters when comparing quotes. Anyone selling cable as an emergency fix for an existing dam is selling the wrong product.

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 heat cables pages: Ypsilanti, Novi, Westland, Livonia, Farmington Hills, Taylor.
Coverage runs across Ann Arbor and the nearby towns all winter, and capacity is surged into whichever Michigan market the storm actually hits.
Most jobs do not stop at one service. Heat Cables in Ann Arbor often runs alongside ice dam removal in Ann Arbor, and both get written into one scope rather than billed as separate visits.
