Ice storm and freezing rain

Habitation Ice storm and freezing rain

Ice storm and freezing rain are feared weather phenomenon due to the weight of ice that can do a lot of damage to buildings and outdoor structures. They can also be the cause of power outages and occur without warning from November to April at temperatures close to 0°C.

Tips to reduce risk of damage

  • Examine the surroundings of the roof to see if ice barriers and ice cubes have formed. Flatter slopes are more exposed to ice formation, but any structure can be vulnerable.
  • Clear the roof of snow before successive layers of ice and snow accumulate too much. The weight and tension of ice and snow are the main causes of roof collapse.
  • In the attic, check if openings could cause heat loss.
  • Make sure that the fibre glass insulations are tightly packed and adding a layer of it increases sealing and prevents heat from escaping in the attic and forming ice around the roof.
  • Check that there are no tree branches that could sag on the roof and electrical wires and near the windows.
  • Make sure gutters and downspouts are not obstructed to facilitate the flow of water.
  • Apply de-icing on exterior passages (entrance to the house, stairs, sidewalks, etc.) to prevent falls and injuries.
  • In the event of a power outage, have a 72-hour emergency kit on hand, and if possible, an auxiliary heater such as a generator.
