Intent

Intent 1:

To limit the probability of discontinuous roofing, which could lead to inadequate protection from wind-driven rain, which could lead to:

  • water penetrating directly to roof decking or sheathing, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

  • an inadequate control of relative humidity, temperatures of interior spaces or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of roofs or walls or of assemblies protected by roofs or walls.

This is to limit the probability of:

  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.

This is to limit the probability of harm to persons.
