If it currently has a coating on it you will do best to remove that coating before applying a new one. The problem with the coatings that are readily available for DIYer's is they do not last and once you apply it once you are committed forever to reapply as needed. The best solution long term is for you to contact a few local commercial roofing companies and get their take on your problem. Be leary of multiple coats of anything on your roof as the trusses likely weren't engineered to take that kind of load.

There is no ponding or rust that we know of on the roof. We are located in Sebastopol. Rhyne Design Cabinets on Morris Street. California. Anyone have a name or brand of coating that is the best to use?
