ice dam problem
Well, it isn't quite a disaster, but bad enough, and I am looking for some helpful info. I have had an ongoing problem with ice dams on one section of the roof in the 8 years I have owned this house. My first step was to insulate the attic. No ice dams for the first couple of years following that, probably because we had rather mild winters. First normal winter we had the ice dams were back, although not quite as bad as before. Now, over this past weekend, I awoke to find water pooling on the inside of my bow window all over the sill and the floor. The ice dam has been cleared off, but I am concerned because I had the roof replaced a year ago, and the work included the ice/water shield under the 1st 4 feet of the roof. Shouldn't this have prevented the water from coming into the house? The roof replacement also included improving the roof ventilation (added a ridge vent) so I am wondering what else I can do to prevent this problem. Thanks for any helpful suggestions!
