Sentence 9.26.8.5.(2)

Intent 1:

To limit the probability of:

• the displacement of shingles under wind-uplift pressure, which could lead to the exposure of underlying edges of roof shingles, or
• the exposure of fasteners to water from wind-driven rain or capillary action, which could lead to the corrosion of fasteners.

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.
