Rockingham 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 Exeter winter roof services, crews handle heated roof & gutter cables across Rockingham County.
Why Exeter Roofs Dam Up: Nor'easter Load and the Maritime Swing
Rockingham County gets the worst combination for ice: snow with high water content, followed by temperatures that oscillate rather than settle. The pack does not stay frozen and it does not drain.

Older Rockingham County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Rockingham County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal New Hampshire, and many towns enforce it strictly. Homes that have not been re-roofed since that became normal practice are the ones that leak first.
Heated Roof & Gutter Cables in Exeter: How The Work Runs
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. Icicles and a Wet Ceiling.
Scope, circuit loading and control strategy get worked out with whoever maintains the Exeter building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.
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.
Retrofit against installing during a roof replacement
Cable can be added to an existing roof at any time and usually is. If an Exeter 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.
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 Exeter property that gets both rarely needs an emergency call again. One that gets only cable usually needs fewer.
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 Exeter installs.
Done properly it is an ordinary piece of exterior electrical work and it should look like one.

Neighborhoods and Towns We Reach From Exeter
Crews working Exeter cover the adjoining communities on the same route — Newfields, Stratham, South Hampton, Hampton Falls and Newmarket — so a storm week usually means one truck handling several addresses in Rockingham County rather than separate trips.
Nearest hub towns with their own heat cables pages: Durham, Portsmouth, Dover, Derry, Salem, Somersworth.
Scheduling for Exeter 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 Exeter often runs alongside ice dam removal in Exeter, and both get written into one scope rather than billed as separate visits.
