Roof replacement in Orlando, FL
A third of Orlando's housing, 32.6%, went up before 1980, decades before Florida's first statewide building code took effect in 2002. That gap is what a roof replacement in Orlando, FL has to close: the code calls for extra deck nails where the old ones fall short, a secondary water barrier, and inspections by the city.

Local know-how
Pre-1980 decks and the re-nailing rule
Orlando's housing runs older than the county around it: the city's median home dates from 1992, Orange County's from 1994. On a house that age, the first thing a tear-off exposes is the deck. Florida's re-roof rules say that when a covering comes off a plywood or OSB deck, any staples or 6d nails get supplemental ring-shank nails no more than 6 inches apart. Existing 8d nails spaced wider than 6 inches get filled in to the same spacing.
Then comes the secondary water barrier. Whenever a covering is removed and replaced, the code requires one under the new roof (R908.7.2). That requirement traces to Fla. Stat. 553.844(3), which directed the Building Commission to adopt it, along with stronger deck attachment, by October 1, 2007. Insurers must offer discounts or credits for roof features that cut wind losses (627.0629), and they read those features from the wind mitigation form, OIR-B1-1802, so keep the paperwork from this job.
Permits
The Orlando permit path for a new roof
Inside city limits, the permit comes from City of Orlando Permits & Inspections. A re-roof needs no plan review under Florida's code, but it does get a sheathing inspection at dry-in and a roofing inspection covering the dry-in, insulation, coverings and flashing. If the house sits in one of Orlando's six historic overlay districts, settle the Certificate of Appropriateness question with the Historic Preservation Board before the permit.
If only part of the roof is failing, the 25% rule is the other local question. A roof built to the 2007 code or later only has to meet current code where the work is done (553.844(5)). One that predates it cannot have more than 25% of a section redone in 12 months without the whole section coming up to today's code (R908.1.1). The price itself turns on size, pitch, material, layers, deck condition and those code items; start with the quote questions, or compare looks in the design studio.
Questions
Roof replacement in Orlando: questions
What drives the cost of a roof replacement in Orlando?
Size, pitch, material, how many layers come off and how much of the deck needs work set the price, and Florida's code adds its own line items. On Orlando's older stock, where 32.6% of homes predate 1980, deck re-nailing and a secondary water barrier are part of the job whenever a covering is removed and replaced, because the code requires both. Homes in a historic overlay district may add a review step, and time, before the permit. Compare quotes on the same scope, line by line.
Can I put a new roof over the old one in Orlando?
The code decides first. Florida's residential code requires removing every existing layer when the roof is water-soaked or too deteriorated to serve as a base, when the covering is tile, slate or wood shake, when there are already two or more layers, or when blisters have not been cut and secured. The 2023 code's re-cover sections read 'Reserved,' so ask City of Orlando Permits & Inspections whether it will accept an overlay before you plan on one. On houses built before 1980, check how many layers are already up there.
How do I know if my Orlando roof was built to the 2007 code?
Check the date of the last roofing permit. The 2007 Florida Building Code took effect on March 1, 2009, so a roof permitted after that date was built under it or a later edition. City of Orlando Permits & Inspections can give you the permit history for an address inside the city. The answer changes your repair options: a roof built to the 2007 code or later can have 25% or more replaced without redoing the rest. Only 19.7% of Orlando homes date from 2010 or later, so for most houses the roof's own permit is the only way to know.
