Uh, you definitely don't want fucking particle board under your roof. Call the MD Attorney General and a lawyer.

I'm fairly sure he means OSB and it is fine. Depending on the OSB used (Advantech or Legacy) it is at least equal or better then some of the plywood you get today. Not to say that ignoring a contract is ok, but people in here are acting like they put up chip board from Ikea furniture.

they probably do mean OSB, but OSB is NOT equivalent to plywood, especially not in this application.

OSB is approved for flooring and siding, NOT roofing. If it gets wet at all, it’s trashed. Plywood should be used in any situation where they might be water intrusion.

If they pulled permits I’m fairly certain they’d have to put down fire rated plywood

But failing to do so would only be caught on inspection. And that would mean an inspector saw the underlay before the membrane covered it up -- assuming the inspector climbed up on the roof at all.
