You can find a wide assortment of that sort of vent cover at Loews or Home Depot.
Very common product used in Residential and Commercial Construction.
Buy based on actual hole size.
OP I glued small pcs of 1X material on top side of roof panel above screw hole with LocTite PL3 Construction Adhesive then pre drilled holes thru block after adhesive had set. I used a drill bit the size of the shank of the screw so block above would not split when running the screws in.
