By the time a roof in Dover has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Dover winter roof services, crews handle heated roof & gutter cables across Strafford County.
Months of Load: Why Dover Eaves Carry Ice
A roof in Strafford County spends most of the year's coldest months under continuous load. That is a different problem from a single heavy storm, and it produces a different kind of ice.
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 Strafford County eave can be a foot deep and locked to the shingle, with standing water sitting behind it.
Ice-barrier practice in Strafford County
Insulation depth matters at least as much as membrane in this climate, and Strafford 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 Dover: How The Work Runs
What shortens the life of a cable run
Self-regulating cable is generally good for a decade or more. What ends it early is ultraviolet exposure on a run left unshaded through summer, physical damage from somebody raking or shovelling over it, rodents in the gutter, and ice loading on clips that were never rated for it. Icicles and a Wet Ceiling.
A system installed with UV-stable cable, proper clips and a note on the roof plan saying where it runs will usually outlast one that was simply stapled up in a hurry.
Valleys, downspouts and the parts people forget
A zig-zag along the eave with nothing in the valley and nothing down the downspout produces a melted strip of roof draining into a solid block of ice. The water still has nowhere to go, and the dam just forms somewhere slightly different.
A system that works runs the full path: eave, valley, gutter trough and all the way down the downspout to daylight. The downspout run is the piece most often left out and the piece most often responsible for the system not working.
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 Dover building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.
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 Dover property that gets both rarely needs an emergency call again. One that gets only cable usually needs fewer.
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.

Dover Coverage and the Adjoining Communities
Crews working Dover cover the adjoining communities on the same route — Madbury, Rollinsford, Newington, Barrington and Lee — so a storm week usually means one truck handling several addresses in Strafford County rather than separate trips.
Nearest hub towns with their own heat cables pages: Somersworth, Durham, Rochester, Portsmouth, Exeter, Derry.
Dover sits inside the regular New Hampshire service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Heat Cables in Dover often runs alongside ice dam removal in Dover, and both get written into one scope rather than billed as separate visits.
