Roof replacements in unincorporated Miami-Dade follow Florida Building Code reflectance requirements for low-slope commercial roofs, supporting heat-island goals while complying with HVHZ wind standards.
The Florida Building Code Energy Conservation provisions, enforced locally by the Miami-Dade Department of Regulatory and Economic Resources, require minimum solar reflectance and thermal emittance for low-slope roofs over conditioned commercial space. Re-roofing projects must meet these values unless an alternative compliance path documents equivalent energy performance. Residential and steep-slope roofs are not subject to the reflectance mandate but commonly use cool-rated shingles. All roof products must also be approved for the High Velocity Hurricane Zone wind ratings, which limits some membrane options. Permits are required for re-roofing.
Reroofs without permit or non-compliant products face stop-work orders, failed inspection, and fines under Chapter 8CC civil penalty schedule.
