Ice dams are most common in northern climates that are subject to heavy snow buildups on roofs. Ice dams occur when this heavy snow buildup melts during the day and then refreezes when temperatures fall overnight. After several days of the thaw-freeze cycle, it’s common for the ice to work up under the shingles until it reached an area of the roof warmed by your home. This is when your home becomes vulnerable because that ice begins to melt from your home’s warmth and causes a leak. This leak can potentially damage your ceiling, walls and the contents of your home. The problem worsens because insulation loses its R-Value when it gets wet. In cases where the ice dam goes unnoticed for an extended period of time, there can be significant damage to the building and its contents.
There’s no surefire way to guarantee an ice dam won’t damage your home, but there are steps you can take that will greatly reduce the chances of an ice dam forming in the first place. Cleaning your gutters of all debris each fall will allow melting winter snow to flow away from your home through the gutters as it is intended to.
Once winter arrives, make every effort to keep the snow load on your roof to a minimum. Keeping heavy snow loads off your roof serves as a twofold protection. Primarily, it reduces the chance for ice dam formations. These formations may go undetected under a snow load. Secondly, keeping a clear roof will reduce the chance of roof failure due to the excess weight.
