Don’t Let Ice Dams Wreak Havoc On Your Roof

Removing Snow and Improving Attic Insulation Will Save Your Roof

The last thing Long Island homeowners need to contend with is another catastrophe triggered by the weather. So if continuing winter weather has kept you on edge, it may help to remember that you can take a proactive stance with regard to ice dams. In fact, you can absolutely prevent an ice dam from wreaking havoc on your roof, as well as your home and wallet.

Ice dams form on your roof after a series of events takes place. First, snow falls and accumulates on your roof. The heat that escapes from your roof, often because of insufficient insulation, causes the snow to melt. This melting snow and water trickles down your sloped roof as it’s designed to do until it reaches a colder portion of the roof, where it stops and freezes. At this point, an ice dam has formed. The same principle applies to those dagger-like icicles that you may see hanging from the edge of a roof.

Ice dams can form even after a minor snowfall, but the bigger and most dangerous ice dams form after a period of heavy snow and cold temperatures.

The trouble for homeowners occurs when a large ice dam melts or more trickling-down water, blocked against the ice dam with nowhere else to go, seeps into the home through the roof, ceiling and/or trim of windows. The damage can be extensive, and if it’s repaired incorrectly, it can lead to mold growth.

To prevent winter weather damage of this nature:

  • Keep your roof free of snow, if possible.
  • Seal leaks near the attic hatch, chimney, ceiling fixtures, exhaust fans and wires.
  • Inspect your attic insulation and add to it if necessary.
  • Check that exhaust fans are vented outdoors.
