John - if you haven't already, check out Steve's link above. In the NE, hail isn't usually an issue like it is here. I'm still amazed at how many hail storms we get here. Per Steve's link, copper and aluminum roofs tend to dent more easily from hail than a steel roof would.

I know a lot of the old state buildings in Albany, NY are copper and are probably at least 50+ years old. They have that nice patina, like the Statue of Liberty. There are also numerous old buildings in NYC and Boston w/ old copper roofs that seem to be holding up fairly well over time (again guessing 50+ years).

I think to pull off copper, the rest of your house would need to have the "modern" PNW look to it. Otherwise, I think it wouldn't look right on a traditional Craftsman or style housee we typically see around here.
