Ice dams are not a Chelsea 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 Chelsea winter roof services, crews handle commercial ice dam removal across Suffolk County.
Wet Snow, Swinging Air: Chelsea Ice Dams
Coastal snow is heavy with water, and a roof in Chelsea can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.
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 Chelsea.
Ice-barrier practice in Suffolk County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal Massachusetts, 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 Chelsea: How The Work Runs
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 a Chelsea building that distinction shows up as a tenant ceiling two floors down.
Scheduling around tenants
Noise, access, parking and the hours a Chelsea 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.
Overflow scuppers are the tell
Water running out of an overflow scupper in winter means the primary drains are not taking it. On a Chelsea 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.
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 Chelsea 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.

Where We Dispatch Around Chelsea
Crews working Chelsea cover the adjoining communities on the same route — East Boston, Charlestown, Winthrop, West Medford and New Town — so a storm week usually means one truck handling several addresses in Suffolk County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Everett, Revere, Malden, Boston, Somerville, Medford.
Chelsea 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. Commercial Ice Dams in Chelsea often runs alongside commercial roof snow removal in Chelsea, and both get written into one scope rather than billed as separate visits.
