Dam Ice dams

I have had many calls and emails from clients over the past few weeks asking me what to do about the ice dams on their roofs. The most comforting words I have are "you're not alone". Joe Lstiburek at BSC talks about the ice dams and icicles we see everywhere these days (thanks Dave). This articles says about everything there is to be said about the problem. There is no quick fix. Scraping the snow off the roof just damages it, the underlying problem is always lack of air sealing and insulation.
