Doing a reroof in Clay County, Florida.

Clay County, FL (FBC 8th Ed. / 2023 FBC-R) requires strict adherence to FBC-R §R905.2.8.5 and the manufacturer’s installation instructions (FBC-R §R905.1).

1. Profile & Material

• Type: Type D (T-style) or Type F (extended flange) metal drip edge. Minimum 0.019" (26 ga) galvanized steel or 0.024" aluminum (FBC-R §R905.2.8.5).
• Overlap: Minimum 2-inch lap at joints.

*2. Eaves (Bottom Edge) – Under Underlayment*

• Install drip edge directly to deck before underlayment.
• Fasteners: Ring-shank roofing nails (min 12 ga, 3/8" head) or #8 screws.
• Spacing: Max 12" o.c. (FBC-R §R905.2.8.5). Max 4" o.c. within 4 ft of corners/edges if in High Velocity Hurricane Zone (HVHZ) or per FRSA/TRI Florida High Wind Manual (Clay County is 130–140 mph Vult; treat as high wind).
• Seal fastener heads with asphalt plastic cement.

*3. Rakes (Gable Ends) – Over Underlayment*

• Install over the underlayment (and ice barrier if used).
• Same fastener type/spacing as eaves (12" o.c. field; 4" o.c. corners).
• Extend rake drip edge over eave drip edge at corners (shed water).

4. Critical Florida Details

• Seal the Deck: FBC-R §R905.1.1 requires a sealed roof deck (tape seams or synthetic underlayment). Run underlayment over eave drip edge flange; run rake drip edge over underlayment.
• Kick-Out Flashing: Required at all roof-to-wall intersections (FBC-R §R903.2.1).
• Inspection: Clay County Building Dept requires in-progress inspection (dry-in) before shingles. Leave fasteners exposed for verification.

Pro Tip: Use 1¼" ring-shank nails for 15/32" deck; 1½" for 19/32"+. Don’t staple. If deck is questionable, re-nail deck to FBC-R §R803.2.3 (6" edge/12" field) before installing drip edge.

In Clay County, Florida, drip edge installation for reroofing must comply with the Florida Building Code (FBC), specifically the 2023 Florida Building Code, Residential (FBC-R), which adopts the 2021 International Residential Code (IRC) with Florida amendments.

Key Requirements for Drip Edge Installation:

1. Placement (FBC-R R905.2.8.2 / IRC R905.2.8.2): - Drip edge must be installed at the eaves and rakes of the roof. - At eaves: Install drip edge under the underlayment, extending over the fascia and into the gutter (if present). The vertical leg should face downward. - At rakes (gable ends): Install drip edge over the underlayment, with the flange lying flat on the roof deck and the vertical leg extending down the fascia.

1. Overlap (FBC-R R905.2.8.2): - Adjacent pieces must overlap at least 2 inches. - Ends should be lapped so water flows over the lap, not into it (i.e., upper piece overlaps lower piece).

1. Fastening (FBC-R R905.2.8.2): - Fasten drip edge every 12 inches on center using corrosion-resistant nails (e.g., galvanized or stainless steel). - Nails must penetrate the roof deck by at least 3/4 inch or through the thickness of the deck, whichever is less. - Use nails with a minimum head diameter of 3/8 inch (e.g., roofing nails).

1. Material (FBC-R R905.2.8): - Drip edge must be corrosion-resistant metal (minimum 26-gauge galvanized steel, 0.019-inch aluminum, or equivalent). - PVC or plastic drip edge is not permitted in Florida due to UV degradation and wind uplift concerns.

1. Wind Uplift Compliance: - In Clay County (Wind Speed Zone: up to 150 mph, Exposure C), ensure drip edge is securely fastened to resist uplift. The FBC requires enhanced fastening in high-wind zones—follow manufacturer’s high-wind installation instructions if applicable.

Important Notes:

• Underlayment must be installed over the drip edge at eaves and under the drip edge at rakes—this is critical for water shedding.
• Drip edge is required on all roof replacements in Florida (FBC-R R905.2.8).
• If unsure about local amendments, contact Clay County Building Department (904-284-6300) for confirmation—some jurisdictions may have additional requirements.
