If you are in Exeter watching icicles grow along the gutter line, what you are really watching is water that no longer has anywhere to drain. As part of our complete Exeter winter roof services, crews handle commercial ice dam removal 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.
Commercial Ice Dam Removal in Exeter: How The Work Runs
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On an Exeter building that is a sign the roof is holding standing water somewhere above a frozen drain, and the load is being carried rather than shed.
Scuppers are checked first for exactly that reason, and a dry scupper above a wet roof is as informative as a running one.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on an Exeter building that distinction shows up as a tenant ceiling two floors down.
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.
Membrane-safe means something specific
EPDM, TPO and modified bitumen all tolerate steam at low pressure and none of them tolerate chipping, scraping or a pressure washer. Crews steam the drains and scuppers open first to restore flow, then work the ponded ice, and they stay off seams and flashing details with the lance.
Mechanical units, conduit runs, solar racking and safety railing all get worked around rather than over.
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.

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 commercial ice dams pages: Durham, Portsmouth, Dover, Derry, Salem, Somersworth.
Exeter 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. Commercial Ice Dams in Exeter often runs alongside commercial roof snow removal in Exeter, and both get written into one scope rather than billed as separate visits.
