Patina is formed from the oxidation that occurs with copper and the atmosphere. The corrosion or green tint film that occurs is actually very minimal. It virtually leaves the copper unaffected for strength and durability unlike rust which breaks down other metals. Thus the popularity of using copper in outdoor applications like Copper Gutters, Downspouts, and Gutter Covers.
