Are you planning on using 2X4 purlins?
If so, leave the old roofing. Screw the purlins into the rafters, then install your tin.
If you're not going to use 2X4's you should tear off the roll roofing so you can inspect the sheathing. Replace any that's questionable. You have to use bigger screws when fastening tin to the sheathing. Something like #12 or #14 screws VS #9 for fastening to purlins.
Only nail if you're using 2X4's. Nails in the ribs.
Screws in the flats.
Lap so the prevailing wind won't peel the laps. Use the specified caulk in the laps.
Another thing to consider when deciding whether or not to tear off the roll roofing is weight. Will your roof handle the extra weight of the purlins and tin?
