Every Manchester winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Manchester winter roof services, crews handle commercial ice dam removal across Hillsborough County.
Older Housing, Heavy Snow: The Hillsborough County Case
A nor'easter can load a roof in Manchester with heavy, wet snow overnight. Coastal air then swings the temperature either side of freezing for days, which is the exact condition that builds ice fastest.

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 Manchester.
Ice-barrier practice in Hillsborough County
Historic district review in parts of Hillsborough County adds a step on materials and sometimes on color, which is worth knowing before a re-roof is scheduled rather than after the permit is refused.
Commercial Ice Dam Removal in Manchester: How The Work Runs
Scheduling around tenants
Noise, access, parking and the hours a Manchester 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.
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 Manchester property that document is usually the reason the spend gets approved without a second conversation.
Insulation above the deck changes the melt pattern
A modern commercial assembly puts most of its insulation above the deck, so very little building heat reaches the membrane. That is good for energy and it means the snow that lands mostly stays - the roof does not self-clear the way an under-insulated one does.
Where dams do form on those roofs it is almost always at a thermal bridge: a parapet, a curb, a drain bowl or a line of fasteners. Those are the spots crews work first.
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.

Hillsborough County Coverage From Manchester
