When you think of a classic winter scene, a home with the roof lined with icicles may come to mind, but those icicles may not be a good thing. In fact, icicles can sometimes be a sign that your roof is causing ice dams to develop, which can be dangerous and destructive.
An ice dam forms when heat escapes from the home, warming the roof which causes the snow on it to melt, slide off, and then refreeze when it hits the eaves. Sometimes, this is a temporary situation, but other times, the scenario repeats itself over and over, until the ice is backed up the roof, leaving the melted snow with nowhere to go. At this point, the ice can damage shingles, and the resulting water can end up leaking into the attic, potentially causing water damage inside your home.
The fact that enough heat is escaping your home to melt the ice on your roof is an indication that your home isn’t as energy efficient as it could be. Replacing your existing insulation with spray foam insulation like Icynene can help to reduce air loss, because it creates and effective air barrier wherever it is applied.
