Typically anything metal requires metal paint which is going to be pricey. But if your requesting a sealer with color I would suggest going to lowes or home depot into the paint department and simply ask for a metal roof sealer that is tintable. I can't really give recommendations on a brand because every area will have different companies competing based on the areas most common issue ie cold,rain, sun etc. Most sealers will last about 2-5 ysars and need reapplied.
