Minnesota receives a significant amount of snow each year. Sometimes snow is exciting and beautiful, other times snow can be considered a danger. One of the biggest risks to your home materializes from heavy snowfall. The accumulation of snow build up on your homes roof can lead to ice dams, which can lead to major repair expenses. Call our ice dam removal experts today!
An ice dam is a ridge of ice formed by snow at the edge of your roof that stops melted ice water from running off to the ground. The ice dam continues to grow as water backs up behind the ice dam and re-freezes. This cycle continues until the problem area is removed or after the ice dam melts away.
Cause of the Ice Dam:
An ice dam is caused by different heat temperatures on your roof. Warm air can escape into your attic if you don’t have proper insulation and attic air sealing. This means the top of the roof is most often warmer than the bottom, which causes the snow to melt and then re-freeze. This process of melting and re-freezing snow is what forms the ice dam.

Minnesota ice dam prevention should be handled by a licensed and insured insulation contractor. Minnesota ice dams are caused by heat differences in your roof that can stem from multiple problems inside of your attic. Improper insulation or inadequate air sealing can sometimes lead to non-uniform roof surface temperatures that cause ice dams. By having an energy audit completed and eliminating insufficient insulation you will be well on your way to eliminating your ice dams.
This is the major cause of ice dams in Minnesota and can be taken care of by our professional Minneapolis insulation contractor. However, if it’s too late and snow has already accumulated on your roof, it would be a good idea to remove it quickly.
