Your outdoor humidity may be low enough you don't need to worry about the sheet metal sweating if you also wrap it. But before you do. Put a temp sensor on the supply and then cover that area with a piece of insulation 1'X1' of the same value you intend to use. Run the A/C and see how cool it gets. If it gets cooler then the outside dew point, you could end up rusting out your sheet metal before you plan to re-roof.
