Ice Dam Removal in Cambridge, Massachusetts

Every Cambridge winter manufactures its own ice dams: snow loads sit on the city’s period rooflines, heat escaping through 19th-century air-leakage paths melts from the ridge down, and the melt refreezes at cold eaves into a dam that ponds water against shingles. That water goes backward — under the roofing, into eave bays, down top-floor wall cavities. By the time the bedroom wall shows its January stain ring, the cavity has been wet for days. Ice dam removal in Cambridge is steam work plus interior drying plus a recurrence diagnosis — because the same roof builds the same dam every February until the heat path is fixed. Water Damage Pros US handles ice dams across Cambridge and Middlesex County.

How Ice Dams Damage Cambridge Homes

• The melt-freeze cycle — Ridge heat from air leakage and thin insulation melts snow that refreezes at cold eaves; the dam grows with every storm.
• Backed-up water entry — Pooled melt lifts shingle edges and wicks under flashing into eave bays and top-floor cavities.
• Soaked eave insulation — Attic-edge batts clump and stay wet, keeping the deck cold and accelerating the next dam — the cycle feeds itself.
• Plaster ceiling stains — Top-floor ceilings take ring-shaped stains along the eave bays; heavy plaster holds water and sags under load.
• Gutter and edge damage — Dam weight tears gutters and loosens drip edge, opening more entry paths for the next melt.

Our Ice Dam Removal Process

1. Emergency steam removal — Low-pressure steam melts the dam and clears drainage without shingle or gutter damage.
2. Interior water assessment — Eave bays, top-floor ceilings, and cavities checked with imaging and meters for water already inside.
3. Extraction and drying — Soaked insulation and cavities dried with targeted airflow; wet batts replaced where clumped.
4. Antimicrobial treatment — Applied where the 48-hour mold window was crossed — common with dams found days after the storm.
5. Recurrence diagnosis — Air leakage, insulation, and ventilation assessed; the heat path gets a written fix list.

An ice dam is a building-science symptom wearing winter clothes. Steam clears the ice on Tuesday; without sealing the air leaks that feed the ridge heat, Cambridge builds the same dam next February — and every one after. Remove the ice, dry the cavity, fix the heat path. That’s the whole job.
