Roof replacement in Dunedin, FL

Most homes in Dunedin were built in or around 1976, so the roof on your house may be older than the new shingles you are considering. The median build year for Dunedin homes is 1976, plus or minus one year. That age matters because a re-roof in Florida triggers rules that many older roofs were never built to meet.

Dunedin's older housing stock and the roof you have now

About 61 percent of Dunedin's 21,305 housing units were built before 1980. Only about 5 percent were built in 2010 or later. Most homes here have had at least one roof already, and many original roofs are likely past their useful life.

Permits and code

Permit and code rules for a Dunedin re-roof

A full re-roof in Dunedin needs a permit under the Florida Building Code, the single statewide code for repairing and replacing buildings. Dunedin roof permits are handled by the City of Dunedin's building department. The city website could not be checked when this was prepared, so confirm the permit office and current forms there before you sign a contract.

Florida's 25 percent rule says that if more than 25 percent of a roof is repaired, replaced or recovered in any 12-month period, the whole roof covering must be replaced. There is an exception for roofs built to the 2007 Florida Building Code or later, where only the repaired part must meet current code. Your roof's age and past work decide which side of that line you are on.

Confirm the permit with the City of Dunedin before work starts.
Ask whether the roof deck, nailing and secondary water barrier are part of the job.
Ask your insurer whether your roof falls under the 15-year or older inspection rule.

Questions

Roof replacement in Dunedin: questions

What is the 25% roof rule in Florida?

The 25 percent rule says that if more than 25 percent of the total roof area is repaired, replaced or recovered in any 12-month period, the entire roof covering must be replaced. In Dunedin, where about 61 percent of homes were built before 1980, many roofs fall under this rule when repairs add up. An exception applies if the existing roof was built to the 2007 Florida Building Code or later. Confirm how the rule applies to your roof with the City of Dunedin building department.

What is the new law in Florida about roofs?

Florida's statewide code is the Florida Building Code, and the 2023 edition took effect December 31, 2023. Starting December 31, 2026, any permit application filed on that day or later falls under the Ninth Edition, which takes effect then. For a Dunedin home built around 1976, that means a re-roof permitted now must follow the code in force when the permit is filed.

How old are most roofs in Dunedin, FL?

The median year Dunedin homes were built is 1976, plus or minus one year. About 61 percent of housing units were built before 1980. Many original roofs on these homes are likely past 25 years old. For a roof 15 years or older, the insurer must let you have an authorized inspector check it at your expense, and it may not refuse or non-renew the policy solely for age if that inspection shows 5 or more years of useful life left, so check with your insurance agent about your policy.
