What Causes Ice Dams?
Although many homeowners in Minnesota know what ice dams are, few understand why they form. Let us explain!
Due to heat radiating from inside the home or due to heat from the sun, the melting snow runs downs the roof and past the interior wall and freezes along the cold eaves. As the snow continues to melt, standing water collects behind the ice build-up on the eaves and can potentially leak inside the house. You could be looking at significant repair costs due water leaking into the home and damage from the weight of the ice.
Once the ice builds up, the melting snow has nowhere to go. Therefore, the ice accumulates in the gutter area above the roof’s fascia. An ice dam will build as the precipitation continues. As the ice becomes heavier and heavier, it can put the pressure of several hundred pounds across the surface of the roof.
Eventually, an ice dam will give way if the temperature rises above freezing. If not, it will linger throughout the winter season. The weight of the ice can cause a fascia to buckle. Even worse, the ice dam can give way and fall to the ground, creating a danger zone for you, your family, or anyone visiting your home.
