Doctor Copper

I have always liked the sight of fresh copper guttering and downspouts, Swiss-style. I would be interested in knowing what the lifespan is, and cost, relative to baser metals. Clearly the Swiss think the longevity and aesthetics of copper outweigh the cost. Also, the country enjoys low enough crime for theft presumably to be less of an issue.
