I am interested in replacing my shingle roof with either a galvanized steel, galvalum, or aluminum metal roof. My concern is exposure to salt water and salt water air because I live on the coast of Maine in Southwest Harbor. (1) Will this exposure create a problem with the warranty for any of the above painted surfaces? (2) Does this exposure lead you to recommend one of the metal materials noted above over the others? Thank you, Dick Dimond

I would suggest talking to manufacturers about their experience and warranty coverage. You will find that some steel roofs have exclusions based upon proximity to the salt coast. Non-ferrous materials like aluminum, copper, and zinc can work well for these applications.

+1 What style roof were you looking for? Once you have narrowed that down, you can identify the different material types and figure out what is right for your exposure.

Aluminum is the only metal that most coil companies issue a warranty with ( 25 Years.) on the salt water. Standard Galvalume AZ55 or Painted Galvalume AZ50 Steel panels will not have a warranty within 1000 meters of Salt marine environment.

I am concern about salt too on the southern coast of Maine. Curious as to your final desision.

I would recommend that you only use aluminum painted metal with a high performance paint finish such as Kynar 500 or Hylar 5000. The style of the panel will have no bearing.
