The FORTIFIED Factor

Wood Shake and Shingle Sealed Roof Deck Options


Listen Later

In this episode of The FORTIFIED Factor, our AI Experts (informed by Knockout Inspections) break down everything homeowners need to know about sealed roof deck (SRD) options for wood shake and shingle roofs—a critical component for protecting your home against severe weather.

Using guidance from the official FORTIFIED Engineering Standards Technical Bulletin , we explore the two approved SRD installation methods that help prevent water intrusion if your roof covering is compromised:

✔️ Seam tape with a single layer of organic felt
✔️ Two-ply organic felt installation

You’ll learn how these systems work, why proper sealing at the roof deck level matters, and how choosing the right method can significantly improve your home’s resilience during hurricanes, high winds, and hail events.

We also highlight key installation requirements—like proper fastening patterns, material standards (ASTM D226, ASTM D4869), and best practices from the Cedar Shake and Shingle Bureau—to ensure your roof meets FORTIFIED standards.

If you have a wood shake or shingle roof (or are considering one), this episode will help you make informed, weather-ready decisions that protect your biggest investment.
