How close to salt water can a metal roof be in Florida?
It depends on the metal, the finish and the manufacturer. Englert publishes no Galvalume steel warranty within half a mile of salt or brackish water, and from December 31, 2026 the Florida Building Code (9th Edition, Section 1711) generally requires stainless steel for exposed roof fasteners within 300 feet of a saltwater coastline. Check your address with the salt or brackish water check.
