Gonna run OSB vertical on rooftop; so had to install a board beside ridge board w/0.75”gap on each side.
Then installed blocks between purlins at 48” center from 2nd post; I staggered them so I could screw directly into each end, then scabbed the other 2x beside it & toescrewed it on both ends.
Leaving a 3” wide area for where plywood will meet
Only got 4/more sections to do this way & then it’s plywood time.
Btw, so breezy yesterday; blew my 12’ ladder over
