The life expectancy of paint coatings on new weathering steel is at least equivalent to the life of the same coatings on ordinary structural steel. It could even be argued that the life will be longer, as the weathering steel will resist any creep of corrosion under the paint from a damaged area.
Painted metal roofs come with a baked-on factory finish, and you can re-coat these, -- as well as paint bare metal roofing -- with acrylic latex paint. You can also use oil-based alkyd paint, but you need to first apply an undercoat of a galvanized metal primer such as Sherwin-Williams Pro Industrial Pro-Cryl Universal Acrylic Primer. Use the primer even if you add a topcoat of acrylic latex paint, because the primer inhibits rust and bonds better than paint.
