Strength of OSB

I believe a minimum width of 24-inches is the smallest width that can be used on a roof. I have seen smaller than 24-inch strips at the ridge several times. This information seems to be hard to find and shouldn't be!

From LP- OSB install instructions:

Install with the long dimension or strength axis of the panel across supports and with the panel continuous over two or more spans.

Also see IBC Table 2304.7 (3) footnote (a).
