When it gets big enough, it creates a literal dam, so that any water that melts behind it doesn't drip off the roof, it gets dammed up behind the ice mass. Typical asphalt shingles do a lousy job of keeping standing water from infiltrating. The result is water inside the house, often dripping down inside the exterior walls of a home, and dripping out through windows, discoloring drywall, ruining insulation, etc. Bad stuff. Google it, dude. <br /><br />If you shovel all the snow off the roof, there's nothing to melt or drip inside the home.Anonymoushttps://www.blogger.com/profile/12610344574135095983noreply@blogger.comtag:blogger.com,1999:blog-17629790.post-42111192091245696482010-12-21T15:16:47.338-06:002010-12-21T15:16:47.338-06:00what is a ice dam?what is a ice dam?Bill Lindekehttps://www.blogger.com/profile/11373780012930618768noreply@blogger.comtag:blogger.com,1999:blog-17629790.post-47592547795455244912010-12-21T15:14:57.221-06:002010-12-21T15:14:57.221-06:00You shovel a roof to help prevent ice dams!You shovel a roof to help prevent ice dams!Anonymoushttps://www.blogger.com/profile/12610344574135095983noreply@blogger.com
