Don’t Let Melting Snow Flood Your Property or Street


Deep snow can melt into a lot of water. Deep snow very rarely causes flooding by itself. Often, heavy rain and rapid warm-ups combine with rapidly melting snow to cause major flooding problems. Here are some things you can do to be prepared for heavy rains and rapid warm-ups to prevent damage to your property and flooding:

  • Keep gutters clear of leaves and debris to prevent ice dams.
  • Ensure that drains in outdoor basement stairwells and window wells are functional. Remove snow from these areas after the storm has ended. Melting snow can lead to water damage and moisture intrusion.
  • Remove outdoor flower or window boxes hanging on a home’s exterior because snow can accumulate and melt against the building exterior causing moisture intrusion.
  • Ensure that skylights and other roof openings have proper weather stripping or gaskets around the perimeter to keep snowmelt from seeping through.
  • Remove icicles hanging from gutters and over walkways.
  • Keep your attic well ventilated to maintain a temperature close to that of the outdoors and minimize risk of ice dams forming. A warm attic melts snow on the roof, causing water to run down and refreeze on the roof’s edge, where it’s much cooler. If ice builds up and blocks water from draining, water is forced under the roof covering and into your attic or down the inside walls of your house.
  • Check storm drains near your home and business and clear away leaves, debris and heavy snow. Clogged grates are often the reason a street floods under rainstorm or rapid snow melt conditions.
  • Please do not put trash bags into the street as this can be hazardous to traffic and also cause flooding from clogged storm drains.
