Ice dams can absolutely cause leaks and interior water damage. They form when melting snow refreezes at the eave, forcing water under your shingles.

Understanding Ice Dam Damage in MetroWest
- How Ice Dams Form: Snow on your roof melts from attic heat and flows toward the eave. Water refreezes over the unheated overhang, creating a dam that traps more water behind it.
- Water Backs Up Under Shingles: As the ice dam grows, trapped water travels under shingle tabs. Warmer sections of the roof prevent refreezing, and water enters your Babson Park home.
- Interior Damage Adds Up Fast: Ice dam removal can cost up to $4,000. Follow-up repairs like roof leak repair can reach up to $24,000, and shingle repairs range from $130 to $9,000.
- Hidden Damage Develops Over Time: Wet insulation loses its ability to perform, and mold may grow in the damp attic environment. Norfolk County homeowners may not notice latent damage for months.
- Ventilation Prevents the Cycle: Proper ventilation lowers attic temperature, which reduces snow melt on the roof surface. GAF recommends a balanced soffit-and-ridge system to break the ice dam cycle.
- Leak Barriers Add Critical Protection: Membranes like GAF StormGuard or Weather Watch prevent water from penetrating through the roof deck, even under ice dam conditions along the eave.
How to Protect Your Babson Park Home from Ice Dams
Top Recommendation: Combine proper attic ventilation with leak barrier membranes at the eave for the strongest defense.
Best for Prevention: Ensure your attic meets the FHA/HUD 1/300 ventilation standard with a continuous soffit-and-ridge system.
Best for Existing Damage: Schedule a professional inspection to assess insulation, ventilation, and membrane coverage before the next MetroWest winter.
