Studies show that a breathable self-adhering roofing underlayment has the ability to: Provide drying Ease installation Extend the life of the roof assembly This course investigates current knowledge of breathable, vapor-open (permeable) roofing underlayments and their ability to mitigate water intrusion, reduce long-term exposure to wetted substrates, and enhance the drying capacity of the roof assembly — extending the life of the roofing

Upon completion of this course, the Learner should be able to:

• Describe the history of roofing underlayments
• Understand the difference between asphalt felt and synthetic underlayment’
• Define the roof assembly barriers; heat, air, moisture
• Show the mechanisms of vapor-permeable roof underlayments extending the life of the roof assembly
• Articulate why a breathable roofing underlayment provides superior drying capacity over conventional roofing underlayments
• Understand key details when installing a roofing underlayment
