Standard Operating Procedure: Roof Replacement (Broward County, FL)

This SOP provides a comprehensive, compliant, and systematic framework for executing a full residential roof replacement in Broward County, Florida. Given the region’s high-velocity hurricane zone requirements (High Velocity Hurricane Zone - HVHZ), strict adherence to the Florida Building Code (FBC) and local municipal requirements is mandatory. This document is designed for project managers and licensed contractors to ensure quality control, safety, and regulatory compliance from permit issuance to project closeout.

Phase 1: Pre-Construction and Permitting

• Property Assessment: Conduct a thorough inspection of the roof deck, structural rafters, and ventilation. Document existing damage.
• Permit Application: Submit the "Building Permit Application" to the local Broward municipality. Include the Product Approval (NOA - Notice of Acceptance) documents for all roofing materials.
• Notice of Commencement (NOC): File the NOC with the Broward County Clerk of Courts and post a certified copy at the job site.
• Engineering Compliance: Ensure the roof design meets the specific wind-load calculations for Broward County (typically 170+ MPH).
• Contractor Verification: Ensure all subcontractors (e.g., disposal, roofing crew) are properly licensed and insured per Florida statutory requirements.

Phase 2: Site Preparation and Demolition

• Job Site Protection: Utilize plywood or heavy-duty tarps to protect landscape, pools, A/C units, and windows from falling debris.
• Debris Management: Position dumpsters in an accessible location; obtain a street-use permit if the dumpster must be placed on the public right-of-way.
• Tear-off: Remove all existing roofing materials down to the structural deck.
• Deck Inspection: Inspect for rot, moisture damage, or delamination. Replace any compromised plywood/OSB sheathing immediately.
• Nailing Pattern Compliance: Verify the deck nailing pattern meets the current FBC requirements (e.g., 8d nails spaced at 6" on center at edges and 6" in the field, or as specified by the engineer).

Phase 3: Dry-In and Installation

• Underlayment Installation: Install approved secondary water barrier (self-adhering modified bitumen underlayment) per FBC requirements for HVHZ.
• Flashing Installation: Install new drip edges, valley metal, and pipe boots. Ensure step flashing is woven into the wall-to-roof transitions.
• Drip Edge Integration: Ensure the underlayment is properly lapped over the drip edge to prevent water intrusion.
• Material Application: Install primary roofing material (e.g., asphalt shingles, tile, or metal) according to the manufacturer’s installation instructions and the specific NOA.
• Ventilation: Install or replace ridge vents, soffit vents, or attic fans to maintain attic air circulation.

Phase 4: Inspection and Closeout

• In-Progress Inspection: Schedule the "Nailing/Underlayment" inspection with the municipal building department before covering the roof.
• Final Inspection: Schedule the final roof inspection upon project completion.
• Site Cleanup: Perform a magnetic sweep of the entire property to remove rogue nails and debris.
• Project Closeout: Obtain the "Certificate of Completion" from the building department and provide a copy to the homeowner for insurance purposes (e.g., Wind Mitigation report).

Pro Tips & Pitfalls

• Pro Tip: Always take time-stamped, high-resolution photos of the roof deck after the tear-off but before the underlayment is installed. These are critical for wind mitigation credits and insurance verification.
• Pro Tip: Use high-quality "peel-and-stick" underlayment (synthetic) rather than traditional felt to increase the roof’s longevity and insurance rating.
• Pitfall: Failing to verify the "NOA" (Notice of Acceptance). In Broward County, if the product is not explicitly approved for the HVHZ, the building inspector will fail the project, requiring a total redo.
• Pitfall: Ignoring the "HVHZ" wind-load nailing requirements. Using standard residential nailing patterns instead of code-mandated hurricane patterns is the most common cause of inspection failure.

Frequently Asked Questions (FAQ)

1. Is a permit required for a minor repair in Broward County? Yes. While minor repairs (usually under 100 square feet) may have expedited processes, any structural change or replacement of roof coverings requires a permit and inspection in Broward County to ensure hurricane safety compliance.

2. How do I get an insurance discount after the roof replacement? Once the project is complete, hire a licensed inspector to conduct a new "Uniform Wind Mitigation Verification Inspection." Provide this document to your insurance carrier; most Florida insurers are legally required to provide discounts for upgraded roof-to-deck attachments and secondary water barriers.

3. What is the "HVHZ" and why does it affect my roof price? The High Velocity Hurricane Zone (HVHZ) encompasses Miami-Dade and Broward counties. It requires stricter materials and installation methods than the rest of Florida. The "extra" cost covers higher-rated materials, specific nailing patterns, and mandatory municipal inspection fees that ensure your roof stays attached during a Category 4 or 5 storm.
