Local rules that change the job

  • High-Velocity Hurricane Zone

    Miami-Dade County is in the HVHZ. Roofing products need HVHZ product approval (typically a Miami-Dade Notice of Acceptance), and the Florida Building Code's HVHZ roofing requirements apply to installation and inspections.

  • Who issues the permit

    Cities permit homes inside their limits and Miami-Dade County permits unincorporated addresses. A mailing city doesn't always match city limits, so the permitting office is confirmed from the parcel before filing.

  • Older homes

    71% of single-family homes in Key Biscayne were built before the statewide Florida Building Code took effect in 2002. Re-roofing an older home can trigger upgrades such as re-nailing the roof deck and adding a secondary water barrier; a written estimate should include them.
