Is your roof keeping you up at night?
This is quite possible if it’s made of rusting, corrugated steel. Well these old-rusty-mine-shacks-looking-roofs found in Colorado or Utah “ghost towns” are now the rage among Rocky Mountain West’s architects, and you don’t see them just on old shacks anymore, but on multi-million dollar homes and condos. The main material used for it seems to be “CorTen”, the US Steel brand name for that corrugated weathering steel; the generic product name is “rusty corrugated metal” (RCM.)
