Lowes also carries these metal panels. These things kind of snap together. Unless you fill the valleys with Styrofoam and sheet on top of that then cover with roofing (like membrane) it won't be entirely leak proof. Almost leak proof but water can find its way into those seams in a driving rain. If it is just a carport (not some sort of lanai or screen room) I would take the drywall down. BUT you have to figure out how the drywall is mounted. If someone simply put sheet metal screws thru the drywall into the pans you are going to end up with a bunch of holes. Good luck.
