Hi, Ismael. There are ceramic paints and white paints which can reduce the thermal load. However, getting good adhesion to galvanized metal is usually an issue. I would suggest scrubbing the roof with a brush and trisodium phosphate ⇦ on eBay or Amazon [affil link] , then wiping with vinegar ⇦ in bulk on eBay or Amazon [affil link] , then applying a latex Galvanize Primer ⇦ on eBay or Amazon [affil link] [affil link] before applying any top coat. Good luck.
