Ice dams are a leading cause of roof leaks and interior water damage in Massachusetts. Dedham homeowners should understand how they form and what stops them.
How Ice Dams Form and What They Destroy
- The Formation Cycle: Snow on a warm roof melts and travels toward the cold eave, where it refreezes. As the cycle repeats, a wall of ice builds and forces melt water back under the shingles.
- Ice Dam Removal Costs Add Up Fast: Removing an ice dam can cost up to $4,000. That figure comes before addressing any damage left behind.
- Interior Water Damage Is Real: After ice dam removal, roof leak repair alone can climb as high as $24,000. The cost depends on the extent of damage to your Dedham home.
- Shingle and Gutter Damage Follow: Shingle repairs after an ice dam event run $130–$9,000. Gutter cleaning costs an additional $75–$400, and snow removal adds another $200–$700.
- Heat Cable Installation Prevents Future Events: Proactive heat cable installation runs $500–$4,600. That’s far less than the combined repair cost a single ice dam season can trigger.
- Insulation Damage Is Often Hidden: Wet insulation loses its ability to perform over time. Ice dam damage may not appear right away but compounds quietly across multiple winters.
