It depends on the type of metal roofing. I would ask the manufacturer of the particular product you are looking at.
For the vertical exposed fastened panels, hex head screws with metal washers and neoprene rubber seals are used almost always, although some people do use nails.
For hidden fastened standing seam, low profile hidden pancake head screws are usually used.
For metal shingles with hidden fasteners, screws and/or nails can often be used, depending on the product.
Again, check with the manufacturer for specific reccomendations.
