What do you think about putting this in direct contact with PT 1×4?
What about the metal roofing screws too?
Any of it react with the PT?

I would provide a gasket of some material between them, then you are only worrying about the fasteners.
You do mean galvanized not galvalum roofing? Can't have galvalum anywhere near ACQ.
Why do you need PT lumber up there?
But if you do, I'd be putting 15 lb felt over the straps, then the steel. Like fingers said, you still need to think about fasteners that won't be eaten by the ACQ.

Its a pergola that we're going to put the galvanized (26g galvanized not galvalume)
So felt would be out (ohh unless I want to make strips of felt, that I guess is an option). Time consuming but an option-----------------------------------------------------------------------------

Grace membrane on the 1x and SS screws.
But you don't need the PT. No ground contact, no trapped water.
