In this episode of The FORTIFIED Factor, AI Experts (informed by Knockout Inspections) break down one of the most important—but often overlooked—components of a FORTIFIED™ Roof system: the tape used to seal roof deck seams.
Not all tapes are created equal. Choosing the right material can mean the difference between a home that withstands wind-driven rain—and one that suffers costly water intrusion.
Drawing from official FORTIFIED engineering guidance and IBHS resources, this episode covers:
- The two approved tape standards for sealed roof decks:
- ASTM D1970 (modified bitumen)
- AAMA 711-13 Level 3 (flexible flashing tapes)
- Why proper adhesion (no wrinkles, no voids) is critical to performance
- How OSB roof decking can impact tape adhesion—and when primers are required
- The three main tape types homeowners and contractors should understand:
- Modified Bitumen
- Butyl
- Acrylic
- Key differences in temperature performance, flexibility, and durability
- Installation best practices to ensure your sealed roof deck actually performs during a storm
You’ll also learn why pressure-sensitive adhesives depend on proper installation conditions—and how small mistakes can compromise your entire roofing system.
If you’re considering a roof replacement, FORTIFIED upgrade, or just want to better protect your home, this episode gives you the clarity you need to make informed decisions.
