Long story short
If you want to avoid having to deal with ice dams, then we highly recommend roof snow removal. Not only will this decrease the likelihood of the snow freezing up and creating a dam, but snow removal will also lessen the stress on your roof that comes from heavy snow loads.
That’s why we provide roof snow removal in the Twin Cities. We know that the best way to prevent ice dams is to remove the snow as soon as it lands.
Ice dams form when part of your roof’s temperature is above 32 degrees, while another section is below 32 degrees. The warmer section of the roof will melt the snow, causing it to move down your roof. However, it then reaches the cooler part of your roof and refreezes. The result? A pesky ice dam.
