Roof repair in Alachua County, FL

Hurricane Irma in 2017 put Alachua County in the path of a center that passed about 20 nautical miles west of Gainesville. The airport recorded a 61 mph gust and 12.40 inches of rain. Trees came down on homes across the county, so many repairs began with a limb or trunk on shingles.

Four storms in 2024 added to the list. Debby flooded homes and dropped trees on several roofs. Helene's 66 mph gust at UF brought a tree down on a Gainesville house in the Willow Bend neighborhood. Milton followed with gusts to 49 mph and 2 to 3 inches of rain.

Thunderstorms add their own damage. NOAA lists 138 thunderstorm-wind reports and 20 hail reports for the county's zones from 2016 to 2025. The largest hail was 2.50 inches in Gainesville on April 11, 2025. Hail that size can crack and bruise shingles.

Florida's code caps patching at 25 percent of a roof section in any 12-month period. Beyond that line, the entire section has to be replaced or recovered. That cap is the legal divide between repair and replacement. The county's median home dates to 1988. That describes when homes were built, not when any roof was last built, repaired or replaced, and a roof falls under the 2007 exception only if that roof was built, repaired or replaced in compliance with the 2007 Florida Building Code or later, which took effect March 1, 2009.

Newer roofs get a break. When a roof was built or replaced to the 2007 Florida Building Code or a later edition, a repair has to meet current code only where the work was done, and no county may amend that by ordinance. Since 13.3 percent of homes here date from 2010 or later, some owners will fall under it.

The code defines roof repair as renewing part of a roof for maintenance. Whether a minor patch needs a permit rests with the building official. The Alachua County Growth Management Building Division reviews permitted work in the unincorporated areas and several municipalities it does not name, so ask which office covers your address.
