Hurricane Mitigation Retrofits for Existing Florida Homes
Florida homes are at high risk of damage from hurricanes. That’s why the Florida Building Code requires specific hurricane mitigation retrofits for existing site-built, single-family homes.
These retrofits focus on roof-to-wall connections, ensuring homes can withstand uplift forces from hurricane winds. If you’re applying for funding through the My Safe Florida Home Program, this work may be required.
What Are Roof-to-Wall Retrofits?
Roof-to-wall retrofits involve reinforcing the connection where the roof framing meets the wall structure below. These improvements reduce the chance of your roof being lifted off during a hurricane.
Retrofits can be completed with:
-
Metal connectors
-
Straps and clips
-
Hurricane ties
-
Fasteners rated for uplift resistance
According to Section 201.3 of the Florida Existing Building Code, these retrofits can follow prescriptive (standardized) methods or be part of an engineered design.
Prescriptive Retrofit Methods (Section 201.3.1–201.3.4)
1. Gable Roofs on Wood Frame Walls
-
Remove 6 feet of eave sheathing from each side of the gable end.
-
Inspect trusses/rafters for proper anchoring.
-
Install hurricane straps or gusset brackets with at least 500 lbs uplift capacity.
-
Secure top plates to studs where accessible.
2. Gable Roofs on Masonry Walls
-
Same removal and inspection steps as above.
-
Secure rafters to masonry with 2.5-inch embedded masonry screws or to sill plates that are anchored into concrete.
-
All fasteners should be installed within 4 inches of rafters/trusses.
3. Hip Roofs on Wood Frame Walls
-
Remove corner eave sheathing near the hip ridge.
-
Strap or bracket the hip ridge and exposed rafters to top plates.
-
Secure top plate to wall studs where access allows.
4. Hip Roofs on Masonry Walls
-
Expose 6 feet of framing from the hip corner.
-
Attach rafters directly to masonry or anchored sill plate using approved hardware and masonry screws with 2.5-inch embedment.
-
Follow same fastening placement and uplift standards.
Prioritizing Your Roof Retrofit (201.3.5)
-
Gable ends take priority unless the hip roof section is 1.5x wider than the gable.
-
Corners and areas with the longest roof spans should be retrofitted first.
Doing this ensures maximum uplift resistance in your home’s most vulnerable points.
Why This Retrofit Matters
Proper hurricane mitigation retrofitting can:
-
Lower your home insurance premiums
