Hello:-) We have a seemingly common problem with most roofs, significant ice damming on the eaves. Our situation may or may not be isolated but we have 25' vaulted ceilings that were not properly insulated and short of tearing off the shingles and plywood outside or the plasterboard on the interior there is no structural cost effective solution to the existing house. I still think that a metal roof would be the way to go but would like some advise on possible solutions to the heat loss issue so we can replace the gutter system (which the lack of had caused moisture issues on the lower part of the house) when the roof is to be replaced. Thank you in advance and I look forward to your solution.

Some metal roofs could be installed over battens -- vertical battens followed by horizontal. The resulting chamber can then be vented to help with energy efficiency and moisture control.

This will also help to remove the hot spots on the roof to minimize ice problems.

Hi Todd:-) Thank you for the advise. I have another question however concerning the same situation. Can I cover the existing shingles with HouseWrap or foam board and then put the metal roofing over that or will that create a whole new problem?

Some metal roofs can be installed that way, You'd have to check with the manufacturer. However, that will not be as effective as just increasing the ventilation.
