How Do Ice Dams Form in MN?


There is multiple reasons why Ice Dams form on building structures. Two of the most common reasons are a lack of insulation and to much snow on your roof.

Most times when we get large amounts of snow or as we get enough snow built up over time the snow starts to cover up your vents. These roof vents you don't think about often but they are very important. As heat rises your roof needs to breath, these vents allow your roof to do that. Now if your vents are clogged the heat has no where to go, so then it starts to heat up your roof. Once your roof heats up the snow melts, as it reaches the 2' overhang on the edge of your home that is no longer heated it now freezes. Over days of this happening ice dams get large and start to hold water. Once there is to much water it breaks through your roof and you have an unwanted waterfall inside your home or walls.
