Intent 1:
To limit the probability that roof sheathing will
not be installed or that inappropriate roof sheathing will be installed,
which could lead to:
- the structure being unable to distribute the roof loads,
which could lead to an inability to resist expected gravity and lateral
loads, which could lead to excessive deflection or failure of the
structural system, or
- insufficient support of the roofing material, which
could lead to excessive deflection or failure of the roofing material.
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 the deterioration
of the roof or elements protected by the roof, which could lead to
compromised structural integrity of the roof or elements protected
by the roof.
This is to limit the probability of harm to persons.
