INTRODUCTION

This FORTIFIED Home™ standard 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.

Roof Covering Requirements

Shingle roof

Shingle roof coverings must be high-wind rated:
Wind rating requirements: ASTM D3161 Class F or ASTM D7158 Class G or H.

Drip edge
Drip edge must be installed (at eaves and rakes) with 3 in. laps. Drip edge shall extend ½ in. below sheathing and extend back on the roof a minimum of 2 in. Drip edge at eaves and at gable ends shall be installed over the underlayment. The drip edge shall be mechanically fastened to the roof deck at maximum of 12 in. o.c.

Starter strips:
For shingle roofs, starter strips must be adhered at the eave and rake. Either embed the starter strip in roofing cement or use self-adhered starter strips.

FAQs

Ceiling repair times are heavily variable depending on the amount of damage received. For minor drywall repairs, a ceiling replacement can be completed within a few hours of starting. However, if an entire ceiling needs replacing, one should expect such a project to take multiple days to remove and replace all the drywall.
