Wood framed metal roof Quonset Hut roof sheathing/insulation

Hutlife | Posted in Energy Efficiency and Durability on

I have been reading many related articles and I am in a unique situation as I am converting a wood framed dirt floor Quonset Hut in climate zone 5 into a Workshop/small apartment. My plan was to tighten up the roof to prevent leaking and spray 4″ closed cell spray foam the underside. I am starting to think it may be better to take the metal roofing off as i have to replace the nails with screws and butyl tape the seams and install a plywood sheathing on top of the pearlins. I feel like this might add a layer of protection between the roof and the wood frame of the building.
At this point I was hoping to just add an underlayment on top of sheathing and reinstall metal roofing. I would at some point in the future like to replace the roofing with a nicer metal roofing but would like to get by with this for a while. I’m hoping this approach would work just fine with the right underlayment. Any suggestions?
