Requirements Overview

FORTIFIED Home standards address all technical information and installation requirements for FORTIFIED Roof, FORTIFIED Silver, and FORTIFIED Gold designations.

Hurricane

The FORTIFIED Home™ – High Wind Standard (FHHW) addresses high winds common in inland communities. Those inland communities are identified as locations where the design wind speed is less than or equal to 90 mph (Vasd) as determined in ASCE 7-05 or 115 mph (Vult) as determined in ASCE 7-10. The primary goal is to strengthen homes to reduce roof and other forms of property damage, disruption, and loss of use caused by severe thunderstorms, straight-line wind events, and high winds at the outer edges of tornadoes. The full Standard is in the process of editing and updating based on new research findings.
