vapor barrier

hi. my climate is louisiana hot and humid summers/ mild winter.
recently installed roxul insul. r30 in cathedral ceiling.
my question is whether or not to install any type of barrier before the drywall goes up and why or why not?

Vapor barrier, if installed, goes to the hot side of the wall. In your case, I believe that would be outside of the insulation, not between it and the drywall.
