What Causes Ice Dams?
An ice dam is a line of ice that forms along the roof edge, which prevents melting snow from draining off the roof. As your attic warms up from the heat in your house, the snow on your roof melts. If the temperature outside is warm enough, this water will harmlessly run down to your gutters (this is a reminder to always make sure your gutters are clear). But when the temperature stays below freezing, this water backs up behind the ice dam and can seep under shingles and into your house.
The following link contains ice dam prevention tips you can take to ensure your roof is ready for the upcoming winter. These tips relate to:
- Ventilation and insulation of your attic.

Take note that before you start any work, it's important to use a qualified, licensed, professional contractor.
