When a commercial roof assembly in Florida has no Notice of Acceptance (NOA) or Florida Product Approval, it should not automatically be installed, repaired, or replaced without further evaluation. Florida has specific requirements for roofing products and assemblies because roofs must resist wind uplift, weather exposure, fire, and other performance demands. The correct approach depends on the building location, the type of roof work, the applicable Florida Building Code requirements, and approval from the local Authority Having Jurisdiction (AHJ).
First, Determine Whether Approval Is Required
Start by identifying exactly what roof assembly and components are being used. Florida’s product approval system covers many roofing products, including built-up roofing, modified bitumen, single-ply systems, spray-applied polyurethane foam, roofing fasteners, insulation, metal roofing, roof tiles, coatings, underlayments, and other integral roofing components.
A roof assembly may have a Florida Product Approval number, commonly identified by an FL number, or it may have a Miami-Dade County NOA. An NOA is particularly important in Miami-Dade County and other jurisdictions where the AHJ accepts it. However, an NOA and a Florida Product Approval are not interchangeable in every situation.
Search for an Existing Approval
Before assuming that the assembly has no approval, search the Florida Building Commission’s Product Approval database. You can search by manufacturer, product name, model, category, FL number, code version, or other criteria.
Older roof assemblies may have documentation under a previous manufacturer name, product name, or code edition. The manufacturer may also have an updated approval that covers the same or a substantially similar system.
Check the complete assembly—not just the membrane or coating. Roof deck, insulation, fasteners, adhesives, attachment methods, cover boards, and other components may affect whether the proposed assembly complies with the approved system.
Consult the Manufacturer and a Florida Design Professional
If no applicable approval can be located, contact the roofing manufacturer for technical documentation, test reports, engineering calculations, and installation requirements. A Florida-licensed professional engineer or architect may also need to evaluate the proposed assembly.
Florida’s product approval rules recognize evaluation methods such as testing, certification, and rational analysis for demonstrating compliance.
For roofing systems, performance can include wind uplift, weathering, leakage resistance, fire performance, puncture resistance, and other criteria. Florida’s roofing testing protocols specifically address these types of performance characteristics.
Get the Building Official’s Determination
Do not assume that a contractor can simply substitute an unapproved assembly because it appears similar to an approved system. The local building official or AHJ should determine what documentation and compliance pathway is acceptable for the project.
This is especially important in Florida’s high-wind and High-Velocity Hurricane Zone areas, where roof assemblies are subject to stringent performance requirements. Miami-Dade NOAs, for example, contain specific scopes, limitations, installation requirements, and expiration information.
Consider an Approved Alternative
If the existing assembly cannot be documented or approved for the proposed work, the safest practical solution may be to specify a current Florida Product Approved or otherwise code-compliant roof system. This provides clearer documentation for permitting, inspection, installation, and future maintenance.
An approved roof assembly must also be installed according to its approval. Florida roofing requirements can restrict substitution of components because changing components can affect the tested performance of the entire assembly.
Bottom Line
If a roof assembly has no NOA or Florida Product Approval, do not proceed based solely on the contractor’s assurance that the system is acceptable. Verify the assembly through the Florida Product Approval database, contact the manufacturer, obtain engineering or testing documentation when appropriate, and consult the local building official or a qualified Florida design professional.
For commercial roof replacement, restoration, or repair projects, Shieldline Roofing can help evaluate the existing roof assembly and identify a practical, code-conscious roofing solution for Florida properties. Always confirm the final compliance requirements with the project’s AHJ and applicable provisions of the current Florida Building Code.
