The unpainted Galvanized roofs are supposed to be very inefficient from what have read.

It does about the same as the more expensive speciality roof coatings at less cost. I've used Zinsser 1-2-3 as a primer then Kelly-Moore's Low Sheen (their direct to metal paint) or their Gloss Acrylic. applying 2 top coats. Ones I did nearly 20 years ago still look solid white tho the gloss is gone. These were on warehouses/machine shops and the owners said the inside temps did drop 15-22 degrees after the paint was applied.
