How Does an Ice Dam Form?

Posted by at 9:00 AM

As a licensed Minnesota roofing company, one service we offer that many homeowners around the Minneapolis area need is ice dam prevention.  Understanding how ice dams form on a roof's edge is important to getting to a permanent solution that will eliminate this problem.  Ice dams shouldn't be ignored, because they can cause substantial damage to both your roof as well as the interior of your home. This month we came across an informative article from This Old House, and we are sharing this infographic from them because this is one of the best visuals on ice dam formation we've seen.  As you take a look at the first section, you'll understand why our first steps in putting an ice dam prevention solution in place involve adequate ventilation to keep an attic space cool.  Cool attics are important all year round, but especially in winter. We have an addition to the TOH article however - having a metal roof installed.  One of the benefits of a metal roof is that snow slides off rather than building up like it will with other roofing materials.  Avoiding a snow build-up that leads to melting water is one of the best ways to insure that your home won't ever suffer from ice dam formation again.    If ice dams are a problem on your roof every winter, please contact us for a free evaluation of your attic space and a quote to get it taken care of permanently!
