Grafton County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Hanover winter roof services, crews handle heated roof & gutter cables across Grafton County.
Hanover Ice Dams: What a Five-Month Snow Pack Does
The defining feature of a Grafton County winter is persistence. It is not one storm, it is a continuous load sitting on the roof from late fall through to a spring thaw.
A long season is not a safer one. It means more freeze-thaw cycles, and each one adds a layer to the dam. By late winter the ice at a Grafton County eave can be a foot deep and locked to the shingle, with standing water sitting behind it.
Ice-barrier practice in Grafton County
Insulation depth matters at least as much as membrane in this climate, and Grafton County stock built before modern attic standards tends to be short on both. One is a code question; the other is why the dam formed.
Heated Roof & Gutter Cables in Hanover: 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 a Hanover 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.
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.
The failures that give heat cable a bad name are nearly all installation failures of this kind rather than product failures.
Why most cable installations underperform
Not because the cable is bad. Because the path is incomplete. A zig-zag along the first few feet of eave that does not continue into the gutter and down the leader melts a channel that ends in a block of ice.
The water has to get all the way to the ground. On a Hanover install that means eave, valleys, trough and downspout traced as one continuous path, and it is the single thing that separates a system that works from one that does not.
Controls decide the running cost
A cable on a plain thermostat runs through every dry cold snap, which is most of the winter and none of the risk. A combined temperature and moisture sensor runs it only when there is both cold and water present.
On a Hanover winter that difference is most of the operating cost, and the controller pays for itself quickly.
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.

Neighborhoods and Towns We Reach From Hanover
Crews working Hanover cover the adjoining communities on the same route — Etna, West Lebanon, Lyme, Enfield and Lyme Center — so a storm week usually means one truck handling several addresses in Grafton County rather than separate trips.
Nearest hub towns with their own heat cables pages: Lebanon, Claremont, Franklin, Laconia, Concord, Keene.
Scheduling for Hanover tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Heat Cables in Hanover often runs alongside ice dam removal in Hanover, and both get written into one scope rather than billed as separate visits.
