Sentence 9.26.3.1.(3)

Intent 1:

To limit the probability of an insufficient slope of the roof or construction that serves as a roof, which could lead to inadequate drainage or water pooling, which could lead to:

• water accumulation, which could lead to damage to roofing material, which could lead to the premature failure of roofing, or
• water ingress at roofing joints.

This is to limit the probability of precipitation or meltwater ingress, which could lead to further deterioration, which could lead to the structural failure of roofs or assemblies protected by roofs, which could lead to harm to persons.

Intent 2:

To supersede the application of Sentence 9.26.3.1.(1) to allow lower slopes where roofing material specifically designed for lower slopes will be used.
