- Q.Does OSB have the same
nail-holding ability as plywood? I want to use it as
roof sheathing, but I am nervous about
blow-offs.
A. The nail-holding ability of
OSB is similar to plywood. In a 1988 report in
Forest Products Journal, the withdrawal
strengths of both nails and staples in OSB panels
were found to exceed those in plywood. It has been
used as roof sheathing on thousands of houses, and
I have not heard of any blow-offs due to the
fasteners (nails or staples) failing.
