I'm having a problem with a window leak. My house has a built out bay with a window in the center (+/- 5'-0") and two on the sides (+/- 2'-0"). These bays project out about 3'-0" from the face of the house and the roof overhang is about 6" at the bays. So in all the overhang is about 3'-6" from the face of the house. The attic space above these bay is building up ice and now it is dripping down through the wall and out the top of the center window, only in the very middle of the window. It is still below freezing out so the heat from the inside of the house must be melting this ice. Any suggestions?
