Ice Dam Water Damage in Waltham, MA
An ice dam sends meltwater under the shingles and into the attic, the outside walls and the top-floor ceilings, often for days. The restoration team traces where it went, removes what is soaked and dries the rest in place.

Ice dams are a Waltham winter fixture on older capes, colonials and the top floors of two-family houses. The leak usually shows up as a brown stain at the top of an outside wall, a drip at a window head or a sagging patch of ceiling plaster near the eaves, and by then the water has often been running for a while.
First steps for ice dam water damage in Waltham
- I
Catch the drips
Put buckets and towels under active drips and move furniture and rugs away.
- II
Check the ceiling
If plaster is sagging or bulging with water, stay out from under it.
- III
Stay off the roof
Do not chip ice from a ladder or the roof; that is work for a roofer.
- IV
Photograph inside and out
Take pictures of the stains, the ice along the eaves and the attic if it is safe.
How ice dam water damage is handled in Waltham
The tech who does the walkthrough maps moisture before any equipment goes down, so the drying plan follows what is actually wet. Equipment stays until the readings say dry, not until it looks dry.
- 1
Trace the meltwater
Thermal imaging and meters follow the water from the eave through walls and ceilings.
- 2
Remove what is soaked
Wet insulation and failed plaster come out and are bagged and documented.
- 3
Dry the structure
Air movers and LGR dehumidifiers dry sheathing, framing and the ceilings below.
- 4
Verify and record
Readings are logged daily until every wet area matches a dry reference.

How an ice dam leaks
Heat escaping from the living space warms the roof deck and melts the snow above it. The meltwater runs down to the cold overhang and freezes again, building a ridge of ice along the edge. More meltwater pools behind that ridge, works up under the shingles and drips into the attic, down the wall cavity and onto the ceiling.
- Knee walls and slopes in cape-style top floors are the most common leak points.
- Water often runs down the inside of an exterior wall and shows up a floor lower.
- Wet attic insulation stops insulating, which melts more snow and makes the next dam worse.
What the drying team does
The tech who does the walkthrough traces the water from the eave to every stain with a thermal camera and a pinless meter. Wet blown-in or batt insulation comes out of the attic floor and knee wall spaces because it will not dry in place. Plaster that is sound is dried with air movers and dehumidifiers; plaster that has let go of the lath comes down safely. Daily readings on the framing and sheathing decide when the job is dry. Removing the ice itself is roofing work; the cleanup covers everything inside. See ceiling leak water damage for leaks from inside the house.
Cutting down the next ice dam
Air sealing and insulation at the attic floor keep heat out of the roof deck, and clean gutters help meltwater leave. The DOE Energy Saver site covers attic air sealing and insulation, and the National Weather Service Boston office posts the snow and cold forecasts that set up ice dams. The winter pipe and ice dam risk check scores your own roof and attic.

Ice Dam Water Damage questions in Waltham, MA
Why do ice dams happen on some houses and not others?
They form where heat leaks into the attic and warms the roof deck. Older houses with little attic insulation, recessed lights and air leaks around chimneys and stairways get them most.
Is the water from an ice dam clean?
It starts as melted snow, but it picks up dirt from the roof and the attic. It is usually treated as Category 1 or 2, and wet insulation is removed either way.
Do the ceilings have to come down?
Not always. Plaster and drywall that are still firm often dry in place. Plaster that sags, bulges or has separated from the lath is removed for safety.
Does insurance cover ice dam leaks?
Interior water damage from an ice dam is often covered, while the ice removal and roof repair may be treated differently. Coverage depends on your policy, so it is worth checking with your own insurer.
Can I keep living in the house?
Usually, yes. The work area is limited to the affected rooms and the attic, and containment keeps plaster dust out of the rest of the house.
How do I stop it happening again?
Keeping heat out of the attic is the long-term fix: air sealing, insulation and ventilation. Raking snow off the lower edge of the roof from the ground helps in a heavy winter.
