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.
The Chelsea Dispatch Process, Step by Step
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
Why a drainage channel is not removal
Cutting a few channels through a dam so water can get past is quick and it is sometimes sold as ice dam removal. It drains the roof for as long as the channels stay open, which in a Chelsea cold snap can be a single night before they close again.
Removing the dam means taking the ice off down to the shingle along the whole affected run, so the eave can drain the way it was built to. It takes longer and it is the only version that holds.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in Chelsea with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.
Access, ladders and what the crew needs on site
Steam equipment needs somewhere to park within hose reach, and ladders need footing that is not a buried flower bed or a sheet of ice. Clearing a path to the affected eave, moving vehicles off the driveway and unlocking a side gate takes ten minutes and saves considerably more than that on the clock.
Where the only access is through a neighbor's property, that conversation is worth having before the crew is in the street rather than while it waits.

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 crew pages: Everett, Revere, Malden, Boston, Somerville, Medford.
Coverage runs across Chelsea and the nearby towns all winter, and capacity is surged into whichever Massachusetts market the storm actually hits.
