roof not on yet and a whole lotta rain
Plywood soaks up water more than OSB, but it will more than likely recover better once the water's gone. Have you actually seen any swelling?
If you pop holes in the OSB, the exposed edges can simply be treated with exterior paint to help it retain it's water shedding capabilities. Does your OSB have a stamp on it that says 'Exposure 1'? If so, relax.
I spray water seal on my plywood decks, does anybody know if it's worth while putting it on OSB?
