Application
Application 1: 
Roofs that are:
  • pitched at an angle of 60°, or more to the horizontal, and
  • adjacent to a space intended for occupancy within a building.
This applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

Intent
Intent 1: 
To state the conditions under which roof assemblies must be considered as exterior walls for the purposes of the application of Section 9.10.
This is based on the potential radiation hazard of nearly-vertical roofs which, under fire conditions, could radiate sufficient heat to ignite nearly-parallel surfaces of adjacent buildings.
