Ice dams are formed by continual thawing and refreezing of melting snow. Large masses of ice develop as snow on the upper part of the roof melts. The water runs under the snow and refreezes at the edge of the roof.
Additional snow melts and forms pools against the dam, gradually causing water to back up on the roof where it often gets under the shingles and eventually into the house. Causes other than heat escaping from the home include:
The latent damage from ice dams may not be immediately evident. For example, insulation could be getting wet and over time will lose its ability to perform properly. In addition, mold may begin to grow in the moist attic environment. Although ice dams are more prevalent at the eaves, they can (and do) occur anywhere on the roof, especially where there is a change in roof surface temperatures.
Canadian weather is challenging to say the least and, as we all know, there is only so much you can do to avoid its impact. But, having said that, there are some things you can do to minimize the risks of developing ice dams on your roof.
