The only thing confusing is if it's OH2 without a ceiling and then a ceiling is added later making it a combustible concealed space.

There's no such thing as a .10 density under a roof that's pitched at or more than 4:12 2. Spacing can be as much as 15 ft on the slope, but if it exceeds 8 ft on the flat, a minimum head pressure of 20 psi must be used. 3. In no case can spacing on the flat exceed 10 ft. Seriously, does anyone else find the table in NFPA confusing?
