Based on the IBHS FORTIFIED Home standards, roofs must be installed using specific materials and techniques to achieve certification. Regarding shingles, the requirements include:
- Impact-Resistant Shingles: To achieve a FORTIFIED designation, the roof must utilize impact-resistant shingles designed to withstand severe weather and high winds.
- Enhanced Nailing Patterns: Shingles must be secured using stronger nailing patterns. For a Bronze designation, this requires 6 nails per shingle, while Silver and Gold designations require 8 nails per shingle.
- Manufacturer-Approved Materials: Installations should use approved materials from reputable manufacturers such as GAF, CertainTeed, Atlas, and IKO.
These components work together with a sealed roof deck and reinforced attachments to create a system that meets the rigorous wind resistance standards (ranging from 130 mph to 180 mph depending on the certification tier).
