Commercial roofing in Naranja, FL

Miami-Dade sits within the High-Velocity Hurricane Zone, which covers two counties in total. The HVHZ carries the strong hurricane provisions South Florida adopted after Hurricane Andrew, so a commercial roof here is judged under those rules rather than the general Florida requirements.

The HVHZ requires a Uniform Roofing Permit Application completed and executed by a licensed contractor for all new roofing, recovering, reroofing, repair or maintenance. Membrane work gets checked three times: while it is being applied, before anything covers it, and once more when the job is complete. Ask a bidder which inspections they expect and who will schedule them.

• Confirm the proposal lists the HVHZ uniform permit application and who files it.
• Check each membrane against its ASTM standard, such as TPO under ASTM D6878 or EPDM under D4637.
• Ask how the bid handles ponding water and whether drains and overflow scuppers are included.
• Ask whether the bidder states a finished slope of at least 1/4 inch per foot for new low-slope decks.

Under the 25 percent rule, if more than a quarter of a roof area is repaired or replaced within 12 months, the entire roof system generally must be brought up to current code. Compare bids on whether they treat the job as a repair or a full replacement, because the answer changes the scope and cost.
