I have carpentry questions. Construction-type carpentry.

My curved, draped-roof azumaya is gonna need decking for the roof. Because the rafters are curved and draped, the roof decking must be flexible and accommodate a concave curve of 5-6” over a span of 12’ or so in two directions. As such, it’s not a severe deflection but rigid plywood won’t work. What will? OSB, thin plywood, planking? Also, because of matters beyond my control, the roofing on top of the decking (i.e., shingles, tiles, shakes, or whatever) may not happen for a year or three, so I’m thinking pressure treated or marine plywood would certainly work.

Any insights or thoughts?
