Ice dams are not a Somerville problem so much as a Massachusetts one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Somerville winter roof services, crews handle heated roof & gutter cables across Middlesex County.
Wet Snow, Swinging Air: Somerville Ice Dams
Coastal storms deliver the heaviest snow by weight. A single nor'easter can put a wet, dense pack on a roof in Somerville in one night, and the maritime air that follows rarely stays on one side of freezing for long.
Add the architecture and the problem concentrates. Dormers, ells, knee walls and additions over porches all create pockets where warm air meets cold deck, and those are the eaves that dam first on a roof in Somerville.
Ice-barrier practice in Middlesex County
Most Middlesex County towns require self-adhering ice barrier at the eaves on a re-roof permit. In a historic district there may be additional review on materials, which is worth checking before work is scheduled.
Heated Roof & Gutter Cables in Somerville: How The Work Runs
Self-regulating versus constant wattage
Self-regulating cable varies its output along its own length with the temperature of what it is touching: colder sections draw more, warmer sections throttle back. It can be cut to length on site, it tolerates being overlapped in a gutter, and it cannot cook itself into failure the way constant-wattage cable can. Icicles and a Wet Ceiling.
Constant wattage is cheaper per foot and that is the whole of its case. On a roof in Somerville that sees real freeze-thaw cycling, self-regulating is the one worth installing.
What happens when a section stops working
A dead run is usually one of four things: a tripped ground fault, a failed controller or sensor, physical damage at a specific point, or a connection at the end seal that has let water in.
They are diagnosed with a meter rather than by replacing the whole run. Self-regulating cable can generally be repaired in place with a proper splice kit, so a single damaged section does not mean a new system.
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.
Retrofit against installing during a roof replacement
Cable can be added to an existing roof at any time and usually is. If a Somerville 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.
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 Somerville building, because a heat-trace system nobody owns is a heat-trace system that stops working in its third winter.

Somerville Coverage and the Adjoining Communities
Crews working Somerville cover the adjoining communities on the same route — Charlestown, New Town, Allston, Watertown and West Medford — so a storm week usually means one truck handling several addresses in Middlesex County rather than separate trips.
Nearest hub towns with their own heat cables pages: Cambridge, Medford, Boston, Arlington, Everett, Chelsea.
Somerville sits inside the regular Massachusetts 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 Somerville often runs alongside ice dam removal in Somerville, and both get written into one scope rather than billed as separate visits.
