9.23.16.7.(1)

Intent 1:

To limit the probability of an inadequate grade or thickness of sheathing relative to framing member spacing and edge support, which could lead to an inability to resist expected gravity and lateral loads, which could lead to excessive deflection, which could lead to damage to roofing.

This is to limit the probability of compromised structural integrity, which could lead to:

• the structural collapse of wood-frame construction, or
• precipitation ingress, which could lead to deterioration, which could lead to further compromised structural integrity of the roof.

This is to limit the probability of harm to persons.
