Learning Objectives:

  1. Describe the history of roofing underlayments and define the roof assembly barriers: heat, air and moisture.
  2. Discuss the difference between asphalt felt and synthetic underlayment.
  3. Show how the mechanisms of vapor-permeable roof underlayments extend the life of the roof assembly.
  4. Articulate why a breathable roofing underlayment provides superior drying capacity over conventional roofing underlayments, and understand key details when installing a roofing underlayment.

This presentation provides detailed information on how breathable, vapor-open roofing underlayments mitigate water intrusion—extending the life of the roofing assembly. We will also examine how a breathable roofing underlayment can provide drying and ease installation.
