pellet stove thru copper roof: "I am installing a pellet stove whose flue pipe will ..." - Guest User (9/3/2008) | General Discussion | Archive

I am installing a pellet stove whose flue pipe will go up thru a copper roof. The flange used is galvanized and I am concerned about corrosion between copper and galvanized. I have thought about using a rubber boot as an interface between the two metals or even having someone fashion a copper flange. Any thoughts about what I should do?? Thanks.

This is a tricky one. Even if you have something between them, rainwater would bring some elements of the galvanization in contact with the copper. I would consider either as you mentioned a copper flange or else a stainless steel flange.	Nate Libbey 9/3/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11993/find/
I agree with Nate.	Todd Miller Isaiah Industries, Inc. 9/5/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11994/find/
The copper flange solution is a good one but expensive. There is still the problem of the connection between the flange and the pipe itself. I thought that by painting the galvanized flange and using roof tar around all the base to cover everything, the rubber gasket would work. Any thoughts on that. Thanks.
