This can be a problem but keep in mind that what you are talking about will likely be painted galvanized or painted galvalume in contact with painted aluminum. The metallic and paint coatings act as insulators to separate the dissimilar metals. I would suggest trying to separate the materials with an additional coating or underlayment but, except in real corrosive environments, the risk is minimal. The same goes for masonry.
