Most Evanston homeowners find out about an ice dam from the inside — a damp patch on a bedroom ceiling, or water tracking down the inside of a window frame. As part of our complete Evanston winter roof services, crews handle heated roof & gutter cables across Cook County.
Why Evanston Roofs Dam Up: Cycling, Not Snowfall Totals
Three inches of snow and a week of days above freezing and nights below it will build ice on a Cook County eave just as reliably as a foot of snow further north.
That is the part homeowners miss. Total snowfall here is modest compared with the northern belt, so roofs in Cook County are often built and insulated as though ice is not a concern. Then a cycling week in January finds every weak eave at once.
Ice-barrier practice in Cook County
The residential code Illinois follows requires eave ice barrier on new work, and Cook County enforces it. The variable on any given house is simply when it was last roofed.
Heated Roof & Gutter Cables in Evanston: How The Work Runs
Fastening without putting holes in the roof
Clips and standoffs designed for the job, adhered or clipped to the shingle edge. Never a fastener driven through the covering, and never left loose to abrade in the wind. Icicles and a Wet Ceiling.
The failures that give heat cable a bad name are nearly all installation failures of this kind rather than product failures.
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 Evanston building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.
Layout is most of the job
The cable has to trace a complete path: a zig-zag at the eave deep enough to cover the cold overhang, down through the valleys, along the gutter trough and all the way down the downspout to daylight. A zig-zag that stops short of the heated wall line, or a gutter run with no downspout trace, produces a channel that dead-ends into ice.
Systems get a dedicated GFCI-protected circuit, and controls run on a combination thermostat and moisture sensor so the system runs when it matters and not through a dry January cold snap.
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 Evanston installs.
Done properly it is an ordinary piece of exterior electrical work and it should look like one.
Sizing the eave zig-zag to the cold overhang
The zig-zag has to extend far enough up the roof to cover the part of the deck that sits past the heated wall line, because that is the part that stays below freezing.
Measured from inside the attic rather than guessed from the ground. On a house in Evanston with a deep overhang or a cantilever that distance is often further up than people expect.

Neighborhoods and Towns We Reach From Evanston
Crews working Evanston cover the adjoining communities on the same route — Kenilworth, Lincolnwood, Winnetka, Morton Grove and Golf — so a storm week usually means one truck handling several addresses in Cook County rather than separate trips.
Nearest hub towns with their own heat cables pages: Wilmette, Skokie, Glencoe, Glenview, Park Ridge, Northbrook.
When a storm hits Cook County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Heat Cables in Evanston often runs alongside ice dam removal in Evanston, and both get written into one scope rather than billed as separate visits.
