   Can ice dams damage a roof?

   • In addition to leaving you with water damage, ice dams can rip off gutters entirely and damage the roof itself. If you see water starting to pool on your floors or windowsills or leak from the ceiling, head outside and look at your roof. If you see ridges of ice below piles of snow, an ice dam may be the reason for the leaks.

   What is an ice dam?

   • An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation and other areas. Moisture entering the home from ice dams can lead to the growth of mold and mildew.

   What causes ice dams on a roof?

   • Ice dams occur when snow melts on a warm roof and the water refreezes across the eaves. As more water melts high up on the roof, it backs up behind the ice. When that water freezes, the dam grows further. Outdoors, the sheer weight of an ice dam can tear off your gutters or loosen your shingles.

   What happens if a ice dam melts?

   • The ice dam’s weight can tear down gutters, shingles, and downspouts, which can damage your home and make the repair more difficult. Ice and snow will back up behind the dam, and when it melts, it can lead to water leaking into your attic since it can’t flow off the roof via your clogged gutter.
