"An ice dam typically forms along a roof’s edge or valley, underneath a thick blanket of snow. Poor insulation or venting in an attic space can cause the home’s interior heat to escape, melting the snow on the roof.

Snow, which serves as an insulator, only perpetuates the problem. 'The greater the snow depth and the fluffier the snow, the worse this problem gets,' said Patrick Huelman, a University of Minnesota Extension professor who coordinates the U’s Cold Climate Housing Program. 'And the warm weather coming is only going to work against us.'"
