| Intent | Intent 1: To limit the probability of inadequate clearance, which
could lead to an inability to accommodate dimensional changes due to changes
in moisture content, which could lead to jamming of sheet edges, which could
lead to buckling, which could lead to damage to roofing. This
is to limit the probability of precipitation ingress, which could lead to
deterioration, which could lead to compromised structural integrity of the
roof, which could lead to harm to persons.
