Roof replacement in Seminole County, FL

The median home in Seminole County was built in 1988, with a margin of error of one year. Many original roofs from that era are likely past the 25-year mark insurers watch. If yours is one of them, a replacement brings a permit, two inspections and a code check of the deck underneath.

Seminole County figures

The Seminole County numbers behind this page

Housing units (ACS 5-year): 199,565
Share of homes built before 1980: 29.1%
Share of homes built 2010 or later: 12.3%
Median year homes were built: 1988

Housing age

What the age of Seminole County homes means for your roof

Of the county's 199,565 housing units, 29.1 percent were built before 1980 and 12.3 percent in 2010 or later. By our arithmetic, that leaves about 58.6 percent built from 1980 through 2009. Most roofs here are on homes old enough that the original covering has likely been replaced at least once.

Age also matters to your insurer. Citizens Property Insurance wants proof of five more years of useful life for shingle roofs past 25 years old. A shingle roof laid when the 1988 median house went up would be well beyond that line.

Single-family detached homes are 61.4 percent of housing units here, and mobile homes are 2.1 percent. Most replacements are therefore pitched roofs on site-built houses.

Permit rules

Permits and inspections for a re-roof in Seminole County

Florida has one statewide building code for roof work, so the rules are the same in every town. Who issues the permit is local. The Seminole County Building Division handles unincorporated areas, while Oviedo, Winter Springs and Lake Mary run their own offices.

Oviedo's permit page includes a Re-Roof Process and Affidavit. Winter Springs lists a Re-Roof Inspection Affidavit among its forms. Check with your own city's building office before you sign anything, because the paperwork differs.

A permit clock runs once it is issued. Under the code, a permit becomes invalid if work does not start within 6 months, or if work stops for 6 months. An approved inspection within 180 days counts as active work.

On a larger contract, the permit office wants a recorded Notice of Commencement before the first inspection. The code requires the permit card to warn that leaving it out can mean paying twice for the improvements.

What gets checked

Deck nailing, the water barrier and the 25 percent rule

The 25 percent rule says that if more than a quarter of a roof area or section is repaired or replaced in any 12-month period, the whole roof or section must be redone. An older roof that is patched twice in a year can cross that line.

State law carves out an exception for roofs built or replaced to the 2007 Florida Building Code or later, where only the repaired part must meet current code. Counties and cities cannot rewrite that exception. A roof from the 1988 median would not qualify unless it has been replaced since 2007.

State law counts required roof-deck attachment and replacement of wood sheathing as part of roofing work. On a roof from the late 1980s, expect the inspector to look at how the deck is fastened and whether a secondary water barrier is in place.

Local storms

Storm history and choosing a roofer who can pull the permit

Hurricane Milton in 2024 affected 554 structures in the county, with gusts of 60 to 75 mph and 6 to 10 inches of rain. Hurricane Irma in 2017 affected 4,939 of 7,125 residential structures assessed. Roofs here are tested often.

Before you sign, confirm who will actually do the roofing. Florida lets a general contractor hold the job only if it subcontracts the roofing or holds a roofing credential itself. Ask for the roofing license number and look it up with the state.

For anything tied to an insurance claim, call your insurer or agent. Florida law bars roofers from advising on coverage, and every residential roof contract must carry a notice telling you to check with your insurer first.

What is the 25 percent rule for roofs in Florida?

If more than 25 percent of a roof area or section is repaired, replaced or recovered in any 12-month period, the whole roof or section must be replaced. A roof built or replaced to the 2007 Florida Building Code or later gets an exception, and only the repaired area must meet current code.

Will my insurer drop me because my roof is old?

Florida law limits that. Once a roof reaches 15 years, the homeowner may pay for an authorized inspector to check it. When an inspection finds that your roof still has at least 5 years of useful life, an insurer cannot deny or drop coverage based on age alone. With a median build year of 1988 in Seminole County, plenty of owners are in this position. Your insurer or agent can tell you how the rule applies to your policy.
