Massachusetts winters bring more than snowflakes and sledding. For homeowners, they also bring the hidden threat of ice dams—those thick ridges of ice that build up along your roof’s edge and silently cause thousands in damage. If you live in Dedham, Norwood, West Roxbury, or anywhere with heavy snowfall and fluctuating temps, here’s what you need to know.
What Is an Ice Dam?
An ice dam forms when warm air in your attic melts snow on the roof. That meltwater runs down to the colder edges and refreezes, creating a barrier that blocks drainage. Water then backs up behind the dam and seeps under shingles, eventually leaking into walls, ceilings, and insulation.
Signs of Ice Dam Damage
- Large icicles hanging from roof edges
- Water stains on interior ceilings or walls
- Sagging or bubbling paint near windows
- Cold drafts or wet insulation in the attic
What Kind of Damage Can It Cause?
- Soaked insulation (reducing energy efficiency)
- Mold and mildew inside walls
- Rotting roof decking and framing
- Ceiling and drywall damage
- Paint peeling or discoloration
How to Prevent Ice Dams
1. Improve Attic Insulation & Ventilation
Cold attics reduce the chance of snow melting too fast. Ensure your attic is insulated to R-49 or higher and ventilated properly.
2. Seal Air Leaks
Check around light fixtures, chimneys, and attic hatches to stop warm air from rising into the attic.
3. Use a Roof Rake After Snowfalls
Pull snow down before it has a chance to melt and refreeze. Be careful not to damage shingles.
4. Install Heated Roof Cables (If Needed)
These can help prevent dams in chronic trouble spots, like north-facing eaves.
