Intent 1:
To limit the probability of:
- inadequate bonding with bitumen, which could lead to
displacement due to wind scouring or traffic,
- degradation of aggregate due to water absorption and
freeze-thaw cycling, and traffic, or
- inadequate protection from ultraviolet light from the
sun, which could lead to a loss of necessary physical properties.
This is to limit the probability of
water penetrating directly to roof decking or sheathing, which could
lead to deterioration, which could lead to the structural failure
of roofs or assemblies protected by roofs, which could lead to harm
to persons.
