Roofs, flashings, rain gutters, downspouts, domes, spires, vaults, and doors have been made from copper for hundreds or thousands of years.

Some of copper's other important benefits as an architectural material include its low thermal movement, light weight, lightning protection, and its recyclability. COUNT 5
