9.26.11.4.(2)

Intent 1:

To limit the probability of:

• the dislodgement of roofing membranes under wind suction pressure, or
• an inadequate protection of roofing membranes from exposure to 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.
