why not use the EPDM rubber roofing material used on most RVs. its probably not much more than aluminum in cost and probably easier to install. use Dicor self leveling sealer for any penetrations and you'll be good to go. I sure wouldn't want an aluminum roof with screws of any kind in it if I was looking for long life. Google RecPro, Dicor EPDM roofing

Because "EPDM" and any other flexible non metallic roof solution is a short lived 10yr-15yr fix.
Aluminum can often go 30yr-50yrs without being replaced which makes aluminum far cheaper but yet far superior overall. RV industry moved to using EPDM, vinyl roofing because it is cheaper than aluminum roofing, requires less skill and less labor to install which = MORE PROFITS. It was not because it was better than aluminum!
As far as the OPs question, aluminum roofing does not need glued down, it is secured via screws around the entire perimeter, the middle floats. In fact it needs to float to allow for expansion and contraction with temperature changes.
The only places that will need screws is vents to hold the vents in place.
The perimeter screws are hidden via the trim pieces at the top of the walls.
The aluminum roofing is folded down over the side walls, then the top side wall trim is installed, a bead of butyl caulking is what is used to water proof between the roofing, walls and trim.
