Roof replacement in Lake Mary, FL

The median Lake Mary home was built in 1997, with a margin of error of two years. That suggests many original roofs are close to 30 years old. A replacement here needs a permit from the City of Lake Mary Building Division, two inspections, and work that follows the Florida Building Code.

Roof age

What a 1997 median build year means for your roof

Seminole County as a whole has a median build year of 1988, so Lake Mary is about nine years newer . Only 12.6 percent of homes here predate 1980. Even so, a 1997 shingle roof is old for Florida sun and storms.

Age matters for insurance too. Citizens sets its line at 25 years for shingle roofs, and past it the insurer wants documentation showing five more years of useful life. Florida Statute 627.7011(5) adds that a carrier cannot drop a policy solely for roof age when an authorized inspection finds five or more years left. Your insurer or agent can tell you how this applies to your own policy.

Another 27.2 percent of Lake Mary homes were built in 2010 or later, against 12.3 percent countywide. Those roofs are likely under 20 years old and may not need replacement soon.

Permit rules

Lake Mary permit steps, inspections and the 25 percent rule

The City of Lake Mary Building Division handles roofing permits for homes inside city limits. Seminole County's Building Division separately lists solar panel re-installation requirements after re-roofing, which matters if you have panels.

Florida Building Code section 1511.1.1 says no more than 25 percent of a roof section may be repaired, replaced or recovered in any 12-month period unless the whole section is replaced. One exception applies. If the existing roof was built or replaced to the 2007 code or a later edition, only the new portion must meet current code. Florida Statute 553.844(5) bars local governments from amending that exception.

Paperwork follows the permit. The permit card warns that skipping a recorded Notice of Commencement may mean paying twice, and your first inspection will not go forward without that notice on site. The clock also runs on you: the code voids a permit if no work starts within 6 months.

Job scope

Deck nailing, water barrier and who may do the work

A replacement is the time to deal with the roof deck. Florida law counts required roof-deck attachments, and repair or replacement of wood sheathing found during the job, as roofing contractor work. A homeowner can also ask whether the deck nailing and a secondary water barrier are being addressed, since the state's My Safe Florida Home program has covered both for eligible homestead owners.

Owner-occupants hold 62.9 percent of occupied Lake Mary homes, so most replacements are decisions by the household that lives there. Under Florida Statute 489.113(3), a general contractor must subcontract roofing unless it holds a roofing certificate or registration. Ask who will hold the permit and who will be on your roof.

Questions

Roof replacement in Lake Mary: questions

Do I need a permit to replace my roof in Lake Mary?

Yes. The City of Lake Mary Building Division is where you apply for your roofing permit. Florida's single statewide building code governs roof construction and repair, so the rules do not change from one neighborhood to the next. A recorded Notice of Commencement has to be posted on site before your first inspection. Confirm current forms and fees with the Building Division before work starts.

What is the 25% rule for roofing in Florida?

It says no more than 25 percent of a roof section may be repaired, replaced or recovered in any 12-month period unless the whole section is replaced. There is an exception. If the roof was built or replaced under the 2007 code or later, only the new portion must meet current code. The median build year for Lake Mary homes is 1997, but that describes the homes and says nothing about their roofs, and a roof falls under the 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.

How long is my permit good for?

Not indefinitely. Under the code, a permit becomes invalid if work does not start within 6 months of issuance, or if work is suspended or abandoned for 6 months. Work counts as active when the permit has an approved inspection within 180 days. A Lake Mary homeowner should ask the City of Lake Mary Building Division about extensions before a job stalls.

Does a roof over 25 years old affect my insurance?

It can. Citizens asks for proof of at least five years of remaining life on shingle roofs older than 25 years. Florida Statute 627.7011(5) lets you have an authorized inspector check a roof 15 years or older, and bars non-renewal solely for age if five or more years remain. Lake Mary's median build year of 1997 puts many roofs at that age, so call your insurer or agent.

How old are the roofs in Lake Mary likely to be?

Many are probably close to 30 years old. The median Lake Mary home was built in 1997, and only 12.6 percent of homes predate 1980. By contrast, 27.2 percent were built in 2010 or later, so those roofs are newer. A roof inspection, not the build year alone, tells you how much life a given roof has left.
