the roof has a SE exposure and snow/thaw cycle creates ice dams in late winter. I found that some over the counter heat traces are not for use on metal roofing and many don't provide much information. I prefer something I can source locally but lack information as to suitability for metal roof makes me hesitate to order electronically Any suggestions will be appreciated. Thanks, Peter

What sort of metal roof do you have now? Can you send me a picture? [email protected]

Thanks, Here is roof detail of feeder using left material of house roof. It is smooth painted steel. The house has one large dormer over dining room with SE facing valley which is where buildup occurs. Construction is foam filled 6" prefab panels R-40 on log perlins. Hope this helps. P

If you have a boiler system you could create a hydronic system for energy efficiency. Otherwise, you're looking at electric heat cable that will require hangers screwed into the roof and sealed.

Thanks for this, My problem is finding a heat trace that is good for metal roofing. Several have indicated not for metal but none so far spec for metal. Is there something inherently bad about heat trace on metal or is it just that they don't include installation hardware necessary for metal? I will keep drilling and share findings if any. Cheers, P

I believe it is a matter of fasteners, not products.
