Sealed Roof Deck Membranes & Ring-Shank Fastening Standards

Traditional roofing underlayment frequently tears away when shingles blow off during high-wind events. The FORTIFIED Home™ standard solves this vulnerability by requiring roof deck seams to be sealed with 4-inch wide self-adhering modified bitumen tape, followed by synthetic underlayment, or by applying a continuous peel-and-stick membrane over the entire plywood substrate.

Self-adhering polymer-modified bitumen seam tape installed over all plywood or OSB joints

Frequently asked questions

How long does an IBHS FORTIFIED Roof™ designation certificate last?

A FORTIFIED Roof™ certificate is valid for five years from the date of issuance. It can be re-certified for subsequent five-year intervals through a simple inspection confirming shingle and flashing integrity.

Can an existing roof be retrofitted to FORTIFIED standards without replacement?

Achieving a FORTIFIED Roof™ designation requires a full tear-off down to the bare decking to verify sheathing thickness, nail spacing, and deck seam taping. It cannot be certified over existing shingles.
