WHDH-TV Boston, Weight of winter causes roofs to collapse
Roofers for GF Sprague have answered more than 100 calls, but how do you prevent ice dams? "You can insulate your house, you can vent it, and the most important thing to do is call a qualified contractor to come take a look at it," said Bob Scribner, GF Sprague & Co. At one home in Newton, snow slid right off of the slate roof, and the avalanche ripped a gutter from the front of the home in the middle of the night. "My wife heard a noise, but I was sleeping, so I saw it when I came out to...the driveway," said Matt Matthews, a homeowner. Before you venture up on the roof, make completely sure that it is structurally sound.
