Miami Dade County, Florida Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Miami-Dade County Roofing Permit Requirements

Miami-Dade County's Department of Regulatory and Economic Resources (RER) Building Division handles permit applications for properties located in unincorporated areas of the county. If your property is within an incorporated city, you must apply through that city's building department. All of Miami-Dade County is within the High Velocity Hurricane Zone (HVHZ), which mandates stricter building product approvals and higher wind-load ratings.

For roofing projects in unincorporated Miami-Dade County, permits are generally required for re-roofing and roof replacements. The county offers an E-Permitting system for qualified contractors to obtain permits remotely for certain types of roofing, including TPO and PVC membrane roof assemblies, which can be combined with metal panels, shingles, or tile permits. This system allows for online application, payment, and permit card printing for eligible projects.

Key Requirements and Procedures:

Jurisdiction: Miami-Dade County RER Building Division issues permits for unincorporated areas only.
HVHZ Compliance: All exterior building products, including roofing, must have a Miami-Dade Notice of Acceptance (NOA) or equivalent test certification due to the High Velocity Hurricane Zone designation.
E-Permitting System: Available for contractors to obtain permits online for specific residential roofing types in unincorporated areas. Commercial re-roofing permits generally cannot be obtained through this system unless they are a subsidiary requirement on a master building permit.
Required Forms: The Uniform Roofing Permit Application is required for all roofing permits. Additional forms may be necessary depending on the type of roof system (e.g., shingle, metal, tile, low slope) and may include Ridge Ventilation Calculations, Section D forms for specific roof systems, and Section E for tile calculations.
Owner-Builder Permits: An additional form is required for owner-builder permits.
Product Approvals: Ensure all roofing products used have the necessary Miami-Dade NOA or equivalent certification.
Plan Review: Initial plan review typically takes 1 to 10 business days.

Florida Roofing Legislation, Codes, and Guidelines

Florida State Building Codes and Legislation for Roofing

The State of Florida utilizes the Florida Building Code (FBC), which is a single, statewide building code. The FBC is based on national model codes, such as the International Building Code (IBC) and the International Residential Code (IRC), but it is amended to address Florida's specific climatic needs, particularly regarding high-wind resistance and hurricane protection. The code is updated on a triennial cycle. As of early 2026, the state is operating under the 8th Edition (2023) of the Florida Building Code, which took effect on December 31, 2023.

Key aspects of Florida's roofing regulations include:

Regulatory Authority: The Florida Building Commission, a 17-member technical body established under Florida Statutes (specifically Sections 553.76 and 553.77, F.S.), is responsible for the development, maintenance, and interpretation of the Florida Building Code. The Commission operates within the Florida Department of Business and Professional Regulation (DBPR).
High-Velocity Hurricane Zones (HVHZ): Certain areas, such as Miami-Dade and Broward counties, are designated as HVHZ and are subject to stricter roofing standards, including enhanced wind-uplift, underlayment, and product-approval requirements.
The 25% Rule: Historically, the FBC included a provision stating that if 25% or more of a roof was damaged or replaced within a 12-month period, the entire roof had to be brought up to current code. Recent legislative changes, including Senate Bill 4-D (2022), have clarified this rule. For roofs permitted and installed under the 2007 FBC or later, only the damaged or replaced portion is generally required to be brought up to current code standards, rather than the entire roof.
Permitting: Florida law requires a building permit for nearly all roof replacements and major repairs. Local jurisdictions (cities and counties) are responsible for enforcing the FBC, issuing permits, and conducting inspections.
