Learning Objectives:

  1. Explain the primary functions of a wood-framed sloped roof including four primary, code-based barriers for high performance, green, and sustainable buildings.
  2. Define the common options for wood-framed sloped roofs relating to venting, insulation, and current (2015) code requirements
  3. Review the emerging research and 2018 code provisions that address new variations in unvented wood-framed sloped roof assemblies
  4. Compare some of the different methods for providing continuous and integrated air, water, and thermal barriers in roof assemblies.

A comprehensive overview of the control layers of a wood-framed sloped roof assembly. New code provisions will be discussed for high-performance, green and sustainable building practices. The differences between vented and unvented assembly requirements will be defined. In conclusion, a review of the emerging 2018 code provisions will be done as well as a comparison of different methods to providing continuous and integrated air, water, and thermal barrier.
