My Canadian West Coast (rain forest) cedar architect friend, Henry Mann,
says he "has never heard of a problem between cedar and copper but that
doesn't mean there might not be something he doesn't know." He did say
there is a tradition here for putting a strip of copper along the ridge of a
cedar roof to prevent moss from growing on the shakes.
In 1967, I built one of his solid cedar houses that had perimeter termite
shields made of copper. The sheet metal form was designed to be seen as a
junction between the wood above and the stone and concrete foundations
below, and worked as a nice part of the total design. It kept termites away
too! The roof had copper flashings at all the valleys and chimney. There
were no eaves troughs on that house since the roof overhang was enough to
allow water to simply be shed to the native rocks below.
We have never learned of any problems with the copper there, but then the
location was in a pristine part of the coastline, far away from city smog.
Don't know if that made a difference. We breathe fresh air up here and
drink clean water, just like in the old days back east.
