Homeowners across Strafford County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Rochester winter roof services, crews handle commercial ice dam removal across Strafford County.
Why Rochester Roofs Dam Up: Deep Cold and a Long Snow Season
The defining feature of a Strafford 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.
Every mild afternoon through that stretch releases a little meltwater, and every cold night sets it at the overhang. Done fifty times, that is how an eave ends up carrying several hundred pounds of ice by March.
Ice-barrier practice in Strafford County
Because the ice here does not stay near the edge, the New Hampshire requirement generally runs the membrane well up the roof plane. On a house in Rochester roofed a few decades ago it is frequently missing entirely.
Commercial Ice Dam Removal in Rochester: How The Work Runs
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Rochester unit, there is usually standing water up there.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Rochester call.
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.
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.

Where We Dispatch Around Rochester
Crews working Rochester cover the adjoining communities on the same route — Barrington, Center Strafford, Madbury, Rollinsford and Newington — so a storm week usually means one truck handling several addresses in Strafford County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Somersworth, Dover, Durham, Portsmouth, Exeter, Concord.
Coverage runs across Rochester and the nearby towns all winter, and capacity is surged into whichever New Hampshire market the storm actually hits.
Most jobs do not stop at one service. Commercial Ice Dams in Rochester often runs alongside commercial roof snow removal in Rochester, and both get written into one scope rather than billed as separate visits.
