Rain diverters may seem like a simple solution for keeping water off walkways—but on asphalt shingle roofs, they can create serious resilience concerns.

In this episode of The FORTIFIED Factor, our AI Experts (informed by Knockout Inspections) break down the latest FORTIFIED guidance on rain diverters and explain why they are not recommended on FORTIFIED asphalt shingle roofs. You’ll learn how inserting diverters between shingle courses can break the manufacturer’s seal, increasing vulnerability to wind damage and jeopardizing a home’s ability to qualify for a FORTIFIED Roof™ – New Roof designation.

We also walk through the two compliance pathways outlined by FORTIFIED:

• When rain diverters must be removed and shingles repaired and resealed, and
• When documentation from the shingle manufacturer may allow a diverter to remain installed

Whether you’re a homeowner, contractor, or preparing for a FORTIFIED evaluation, this episode helps you avoid common pitfalls and make informed decisions that protect both your roof and your designation.
