Overview

Florida building code requires that roof decking be re-nailed to specific patterns before a new roof system is installed on a re-roof. This is not optional — it affects the wind resistance rating of the roofing system and the homeowner's insurance coverage. At Trust Roofing, deck re-nailing is a standard part of every shingle re-roof in Florida. This training covers the code requirements, correct nail pattern and spacing, and how to document the completed work for inspection.

Our Field Standards

Deck re-nailing is required on every Trust Roofing shingle re-roof in Florida.

Field standards include:
* All deck re-nailing is completed before underlayment installation begins
* Ring-shank nails meeting Florida building code specifications are used throughout
* The required nail spacing pattern is followed across the entire deck surface
* Re-nailing is completed in a grid pattern that can be visually confirmed
* Completed re-nailing is photographed for permit documentation
* Deck boards with insufficient thickness are flagged for replacement before proceeding

Our Process

Florida Code Requirements

Florida building code requires:
* Ring-shank or screw-shank nail type
* Spacing requirements vary by jurisdiction — confirm with the project manager before starting
* Most standard re-roofs require nails at 6 inches on center along panel edges and 12 inches in the field

The Re-Nailing Process

1. Begin at one corner and work in organized rows
2. Snap chalk lines to establish the correct nail grid
3. Drive nails flush — not over-driven, which damages the panel
4. Work across the full deck surface without skipping sections
5. Inspect each row before moving to the next

Documentation

* Photograph the completed re-nailing before underlayment is installed
* Note the nail type and spacing in project documentation
* Confirm with the project manager that the pattern meets permit requirements

Roofing Terms

Florida Building Code (FBC)

The statewide construction standard that governs all roofing installations, including deck re-nailing requirements, fastener types, and spacing patterns required before a new roof can be installed on a re-roof project.

Ring-Shank Nail

A nail with circular grooves along the shank that provide significantly increased holding power compared to smooth shank nails, required for deck re-nailing under Florida building code.

Wind Resistance Rating

The certified ability of a roofing system to withstand wind uplift forces, directly affected by the deck fastening pattern, and tied to the homeowner’s Florida wind mitigation insurance discount.

Deck Re-Nailing

The process of driving additional ring-shank nails into the roof deck panels before underlayment is installed, required by Florida building code on re-roof projects to improve wind uplift resistance.

Wind Mitigation Inspection

A formal inspection performed by a licensed inspector that documents the wind-resistant features of a roofing system, including the deck fastening pattern, to qualify the homeowner for Florida insurance discounts.
