When I had my roof installed in '06 I had the option of putting ice dam material on the bottom three feet of the roof. It didn't cost much and I'm glad I did it. It's basically a super sticky piece of plastic sheeting that protects the decking from seeing any water should an ice dam occur. Right now I'm glad I chose to have them do it. I think there's only been one other time that the snow/ice has been like this since I had it installed. Still, well worth it.
