Roof protection systems by Benjamin Obdyke

This one-hour course explains how vapor moves through roof assemblies and why moisture control is critical for roof durability. The course is designed for home inspectors and focuses on the relationship between roof ventilation, vapor permeability, underlayments, attic conditions, roof deck moisture, and wood roof coverings.

Special attention is given to wood roof assemblies, including cedar shingles and shakes, and how ventilated roof systems such as Benjamin Obdyke’s Cedar Breather, VaporDry SA, and Rapid Ridge 7 can help manage drying potential.
