A corrosion-resistant strip roofing material which is essentially lead free and is not highly reflective. The coating on the roofing material is a two-phase metallic coating comprised of a large weight percentage of tin and a relatively large weight percentage of zinc. The tin-zinc composition provides for both a highly corrosive-resistant coating which protects the surface of the roofing material from oxidation and also a gray surface coloring which is not highly reflective.
