Sentence 9.26.2.3.(1)

Intent 1:

To limit the probability that the performance of roofing nails, with respect to material quality, gauge, head diameter, dimensional tolerances, finishes and coatings, will fall significantly below expectations, which could lead to:

• fracturing under bending forces,
• inadequate withdrawal resistance,
• pull-through at nail heads, which could lead to an inability to support roofing components and accessories, or
• corrosion on contact with water.

This is to limit the probability of inadequate fastening for roofing, which could lead to the displacement of roofing, which could lead to:

• falling roofing materials, or
• precipitation or meltwater ingress, which could lead to deterioration, which could lead to the structural failure of roofs or assemblies protected by roofs.

This is to limit the probability of harm to persons.
