it, depends on which way your rafters are running ,tongue and grove need to run opposite of rafters, i would think about removing drywall first , incase you have leaks in the future , then your boards willnot be nailed seculy to the rafters (because of the drywall spce shrinkagge) and popcorn texture could get i hnto groves during installation if it was my place i would remove the drywall dan the handyman fullerton ca

Dan the man is right you should remove the drywall. But if you are in a hurry just remove the popcorn and go. Make shure you have a quality roof job. Because the drywall will shrink and move around when wet. Thus cuasing your expensive t&g to become loose and damaged.
