Personally I'd avoid zinc, we had endless trouble with the large
valley on my parents semi. Stripped out the zinc fitted lead not a
problem since in, oo, 30 years... I like lead, only material for small
areas and flashings. He could go posh though and have copper. B-)

Well, I had zinc in the aforementioned bay window roof and on top of the
rear dormer. My next door neighbour has the entire rear addition roof in
zinc. It would seem to have a pretty long life - perhaps 100 years or so.
Of course, like everything, it will depend on the construction and
workmanship.

Copper might not be out of the question for DIY if it's not too large.
