Strafford 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 Dover winter roof services, crews handle commercial ice dam removal 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.
Commercial Ice Dam Removal in Dover: How The Work Runs
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
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 Dover unit, there is usually standing water up there.
What the board or the owner gets
A condition report with dated photographs, what was found, what was done and what is still a risk — in a form that can go to a board, an owner or a carrier without being rewritten.
For a managed Dover property that document is usually the reason the spend gets approved without a second conversation.
Scheduling around tenants
Noise, access, parking and the hours a Dover business can have equipment outside its door all shape when work happens. Some jobs run overnight for that reason.
Set the constraint on the call and the window gets planned around it rather than negotiated on the day.
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 Dover call.

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