A furthyr 2 cents on this. There has been some debate on wether it is better
to use copper (which the tanic acid from the cedar will slowly eat away) or
lead coated copper (which as long as the lead coating does not get any
scrathes or chips protects the copper, but once the lead is damaged the
tanic acid will deteriorate the copper much quicker in the isolated little
pocket where the lead is damaged. Bill Folks would be an excelant source for
additional info on this because this was a hot topic at Jack Waite's office
when Bill use to work there. If you call BCA they can give you a number for
Bill. BCA's # is 212-777-1300.

Donna,

Advise you try contacting Bill Brookover, who's the head Histo Presto
Architect for NPS at Independence Hall National Park.  He has some fancier
title, but what it amounts to is the same, and he told me several years back
about the problems between cedar and copper when I had to do a big cedar
roofing/siding job. As I remember, we used lead coated copper flashing,
since
the contracting types seemed to think that terne-coated stainless steel was
too damn hard to work.

Another guy who would probably know, but I'm not sure how to get in touch
with him, is Bill (Wm. Geo.) Foulks at Bldg Conserv Associates; whether he
works out of their NY or Beantown office, I'm not sure.
