Alternatives to Heat Tape for Preventing Ice Dams
I live in a cold climate and have open eaves. I get extremely bad ice dams to the point where the icicles have now connected to the ground.
I know heat tape is a solution but it seems incredibly wasteful. I know that the typical solution to prevent ice dams is to ensure minimal air leakage between the conditioned space and the roof with appropriate venting, but this seems impossible with an open eave.
I have a roof-on-roof design: the flat rectangular panels pictured are actually just for show and the previous owner jammed fiberglass batts underneath them, which is obviously not super helpful because it’s outside the building envelope.
