FL Certified Roofing Contractor CCC1335466

Charley gusted to 92 mph at the Sanford airport, Milton to 85, and Ian's floods damaged about 1,656 structures. Who issues your roof permit depends on the address. Sanford, Oviedo and Altamonte Springs each run their own building departments and portals. The county's Building Division covers unincorporated areas such as Heathrow through Building Permits Online. If you have solar panels, live under an HOA like Heathrow's, or plan to pull an owner-builder permit, the rules below will change how your re-roof goes.

Code that governs
Florida Building Code, 8th Edition (2023). The HVHZ chapters do not apply here.
Product approval
Roofing products installed in Seminole County need Florida Product Approval (the statewide list at floridabuilding.org) or local approval by the building official, and the work follows the Florida Building Code, 8th Edition (2023). Seminole County is not in the High-Velocity Hurricane Zone, which covers only Miami-Dade and Broward, so Miami-Dade NOAs and HVHZ rules do not apply here.
Design wind speed
All of Seminole County lies between the 130 and 140 mph contour lines on the state's county map for the 2023 Florida Building Code (Figure 1609.3(1), Risk Category II). The 140 mph line runs just outside the county's east edge. Peninsula wind speeds have not changed since the 2010 code.2,3
Homes
199,565 homes; median built in 1988; 71.5% built before 2000; 61.4% detached single-family houses.4

What is on the roofs in Seminole County

The Legislature carved Seminole County out of northern Orange County in 1913, and Sanford, on Lake Monroe, is the county seat and largest city. Heathrow, on the I-4 corridor, founded in 1985 on former celery land, is a private gated community of about 2,200 homes.5,6

Rules, history and conditions that affect roofs here

  • In unincorporated Seminole County, contractors apply through Building Permits Online, and the contractor's license must be current in the county's database. Homeowners pulling their own owner-builder permit must first go in person, with government ID, to the Building Division at 1101 E. First St. in Sanford.1
  • Seminole's Building Division has a separate page on requirements for reinstalling solar panels after a re-roof. If you have panels, read it before the roofer takes them down.1
  • Sanford runs its own Building Division. All building permits there go through the Citizenserve online portal, where you can also pay fees and schedule inspections.7
  • Oviedo and Altamonte Springs also permit their own roofs. Oviedo takes building permit applications online, and since April 1, 2024 any application needing signed and sealed drawings must be filed electronically. In Altamonte Springs, the Building and Fire Safety Department's Civic Access portal handles online permits only for work that needs no plan review.8,9
  • Heathrow, in unincorporated Seminole on the I-4 corridor, is a private gated master-planned community of about 2,200 homes. As in most deed-restricted communities, check your association's exterior rules before you change roof color or material.5
  • The Florida Geological Survey's public subsidence-incident database lists reports from Seminole County. Most reports statewide were never confirmed as true sinkholes, so if you see new wall cracks or a sagging roofline, have a geologist or engineer check it before you assume a sinkhole.10

Storms that shaped these roofs

  • Charley (2004). Charley crossed Central Florida from near Orlando to the Daytona Beach coast on the night of Aug. 13, 2004. Orlando Sanford International Airport measured sustained winds of 72 mph with a 92-mph gust.11
  • Ian (2022). Ian's 10 to 20 inches of rain caused major flooding along the St. Johns River and the Little Wekiva River. The NHC estimates about 1,656 structures were damaged in Seminole County.12
  • Milton (2024). During Milton, the Sanford airport recorded an 85-mph gust and 10.09 inches of rain on Oct. 9–10, 2024.13

What this means for a re-roof in Seminole County

How old the houses are. The median home in Seminole County was built in 1988; 71.5% of its 199,565 homes predate 2000 and 12.3% were built in 2010 or later. So most houses here went up before Florida’s first statewide building code took effect on March 1, 2002.4,14,15,16

Pre-2002 wood-deck houses. When the old covering comes off, the deck gets re-nailed to current code and a secondary water barrier goes on; in the wind-borne debris region, insured homes of $300,000+ may also need roof-to-wall connections (capped at 15% of the re-roof cost).14,15,16

Repair or replace. Replacing 25% or more of a roof section in 12 months generally means redoing the section to current code — unless that roof was built or replaced under the 2007 code or later.15,16,17,18

Product approval. This area is outside the HVHZ, so roofing products need Florida Product Approval (an FL number you can look up at floridabuilding.org); a Miami-Dade NOA is not required.17,19,20,21,22

Roof age and insurance. An insurer can’t refuse a policy just because the roof is under 15 years old. If it is 15 or older, you can get an inspection first; at least 5 years of remaining life means age alone isn’t grounds to refuse.23
