Um, nails, screws ... I don't know.
Seriously, it all has to start with choosing what type of metal roof you are installing. They all have different requirements and fastening methods.
Explore this website a bit, find a product you're interested in, and contact the manufacturer.
All Best. Sorry I cannot be of more help.
