It was suggested to me that galvalume is a better product than galvanized when considering unpainted steel roofing. Specifically, galvalume is more resistant to rusting, and remains shiny longer ( therfore reflects heat& sunlight better). I this true? Also it was suggested that galvanized and galvalume are incompatable? Thanks Aivars Berzins

Both galvalume and galvanized have similar test data and track records. Galvalume may be a bit better for moderate environments. Galvanized perhaps better for real harsh environments or for heavily formed roof panels. Both products will be made better by having a quality paint finish on them. Light colors will be reflective but there are also now dark colors with reflective pigment. I believe that the two metals are compatible.
