Ice Dam Removal in Chelsea, Massachusetts

Chelsea’s January leaks have a signature: a two-day thaw-freeze cycle, a triple-decker whose top floor has been warming the roof deck all winter, and a ridge of ice at the eave or parapet holding a pond of meltwater with nowhere to go but through. Flat and low-slope rooflines on the city’s older triples are especially good at this — snow sits, heat rises, the dam grows, and the ceiling under it stains by dinnertime. Ice dam removal in Chelsea is steam work and structure work: the dam removed without harming the roof, the entry traced, the insulation wetted by the leak dried or replaced, and the heat path documented for the permanent fix.

Why Chelsea Roofs Ice Dam

• Top-floor heat loss — Under-insulated attic flats and old air-sealing gaps warm the deck and start the melt-freeze cycle.
• Low-slope ponding — Flat triple-decker roofs hold meltwater behind dams longer than pitched roofs ever would.
• Parapet and valley freeze points — The city’s parapetted roofs and valley lines refreeze melt exactly where drainage is worst.
• Plaster ceilings under wet decks — Water travels the deck and comes through plaster in stains that undersell the soak.
• Back-to-back storm cycles — Multiple snows refreeze into layered dams that grow all season if the heat path stays open.

Our Ice Dam Process

1. Assessment and interior stabilization — Active leaks caught, stained assemblies checked, sagging ceilings supported.
2. Low-pressure steam removal — The dam cut away without tearing the membrane or shingles beneath it.
3. Entry tracing — The water path mapped through the roof into the assembly below.
4. Assembly drying and insulation decision — Wet deck, insulation, and plaster dried to targets; saturated material replaced.
5. Heat-path documentation — The air leaks and insulation gaps that built the dam mapped for the permanent attic fix.

Chelsea Ice Dam Removal Costs

Service	Typical Range	Notes
Dam removal (roofline)	$600 – $2,000	Steam, per affected run
Dam + interior dry-out	$2,000 – $6,000	Ceiling/wall assembly drying
Dam + insulation rebuild	$4,000 – $12,000	Top-floor thermal repair

The dam is a symptom; the roof deck’s temperature is the disease. Steam it off this week and the next storm rebuilds it unless the top floor stops heating the roof. Fix the January leak twice — once on the roofline, once in the attic.
