First of all, the problem could potentially be more involved than just an incompatibility of paint systems. If you'd like to discuss this possibility further, please give me a call at my office at 1-800-543-8938 ext 201.
Next, though, I'd generally suggest power washing the roof to remove the old paint as best as possible. Then, you should us ea quality primer and paint that are intended for metal. Go to a quality paint store and inquire as to what they have. I know that Sherwin Williams has a primer called Pro-Cryl which is good for applications like this.
I assume that you'll be spray-applying the paint. Allow a week or so of dry time between applying the base coat and the top coat.
Also, you've probably heard about how most manufactured metal roofing today uses "Kynar / Hylar" finishes. What we're using, of course, is a "bake-on" formulation. These finishes are available by special order as air-dry formulations. If you're interested in using this, let me know and I can help you locate it. I will warn you though that these finishes are pretty costly -- about $250 per gallon.
