Steps
Confirm the project is within Florida's High-Velocity Hurricane Zone (Miami-Dade and Broward Counties specifically).
Obtain the current Miami-Dade County Notice of Acceptance (NOA) for the exact shingle product and underlayment being installed, verifying directly on the Miami-Dade Product Control site since NOAs expire and must be renewed.
Confirm the shingle carries the appropriate high-wind classification per the manufacturer's current NOA and product literature, rather than relying solely on a general statewide Florida Product Approval (FL#) number, which is not sufficient for HVHZ.
Confirm the HVHZ-required fastening pattern specified in the product's NOA is followed and documented.
Retain copies of the current NOA documents and photo documentation for the local building department's permit/inspection record.
Known gotchas
A statewide Florida Product Approval (FL#) is not interchangeable with a Miami-Dade NOA — HVHZ jurisdictions require the NOA specifically.
An expired NOA number printed on packaging does not constitute current approval; verify the NOA's current status/expiration date on Miami-Dade's site before installation, not just at time of manufacture.
