What are Ice Dams?

Ice dams are formed when warm interior air escapes into the attic and heats up the roof. The snow sitting on the roof will start to melt and run off but as it hits the roof edge it quickly turns to ice. The ice formation on the roof overhang is caused by cold air inside the cavity of the roof edge (above the soffit).

The melting and freezing cycle will continue over the winter months and since water takes the path of least resistance, it will cause water to pool behind the ice formed at the edge of the roof as you see illustrated above.


  • Wet and settled insulation inside wall cavities causes damp, rotting
    wall cavities
  • Stained ceiling and wall plaster
  • Rapid growth of mould and mildew
  • Wet attic insulation, causing additional heat loss
  • Paint deterioration on soffit and siding

The key to preventing ice dams is simply to keep your attic and roof cold. This can be done by making a few upgrades such as bringing your insulation up to code, adding attic ventilation and changing out your soffits.
