I agree with Todd...the general rule of thumb with Steel roofs is 2,800 feet from salt water however painted aluminum roofs work well in this environment. I wrote an article about this specific topic years ago...

Steel roofs generally would not be recommended for your application. However, there are many aluminum and copper roofs that would work well. See attached photo for a coastal application of an aluminum shake roof,

We live in a townhouse condominium complex situated on a bluff about 100 yards from the ocean. Our zinc-coated and painted sheet metal chimney chase covers and caps have rusted away fairly quickly due to the marine salt-air environment.
We currently have a cement tile roof that has lasted 42 years and needs replacement. Will we have rust problems with if we install a new metal roof?
