When using 1 1/2" metal roof deck (1.5B22) spanning no more than 5'-0", we include a detail that specifies reinforcing for the deck at roof openings up to 8'-0" x 5'-0".
At what point do you say that the opening is small enough that reinforcing is not required? Specifically, I would say that a 4" plumbing vent is OK without reinforcing, but a 24" x 30" roof hatch is not. Somewhere in between is a cut-off size. Is there a common practice?
