Housing in Mulberry

How mobile homes change roof rules in Mulberry

Mobile homes make up 42.2 percent of Mulberry's housing units, against 20 percent for Polk County as a whole. If your home is a mobile home, the roof work and the permit history matter more than they would on a site-built house in most of the county.

Older manufactured buildings fall under separate rules in the Florida Building Code. A building made before March 1, 2002, was built under the Standard Building Code, not the Florida Building Code. Ask the building office which code your home was built under before you plan a re-roof.

  • Hurricane Debby (2024): Polk rainfall maximum 8.03 in near Mulberry.
  • Tropical Storm Debby (2024-08-04): an EF0 tornado touched down in South Mulberry from a supercell in an outer rainband.
  • Mobile homes are 42% of housing units.
  • Older population: 36% of residents are 65 or older (county: 20%); median age 51.4.
  • Water covers 10% of the place's total area.

Roof age and permits

Roof age and the 25 percent rule in Mulberry

The median home here was built in 1989, with a margin of error of 5 years. That places many roofs in Mulberry past 25 years old, which is the age where Citizens asks for proof of remaining life on a shingle roof. Only 11.3 percent of homes were built in 2010 or later.

Under the 25 percent rule, a roof that is not fully replaced may have at most 25 percent of its area repaired or replaced within any 12-month window. For a roof built under the 2007 Florida Building Code or a newer edition, only the section you repair needs to satisfy current code.

  • Hurricane Debby (2024): Polk rainfall maximum 8.03 in near Mulberry.
  • Tropical Storm Debby (2024-08-04): an EF0 tornado touched down in South Mulberry from a supercell in an outer rainband.
  • Mobile homes are 42% of housing units.
  • Older population: 36% of residents are 65 or older (county: 20%); median age 51.4.
  • Water covers 10% of the place's total area.

Storms and rain

Storm and rain risk for Mulberry roofs

Hurricane Irma in 2017 brought a gust to 75 knots near Bartow and 17.61 inches of rain in Davenport. Hurricane Ian in 2022 brought 6 to 12 inches of rain across the county, and the Peace River at Bartow reached its third-highest level on record.

Mulberry gets heavy short rain too. A 1-hour rain in a 10-year storm here falls at 2.87 inches an hour, and a 24-hour rain in a 10-year storm reaches 6.15 inches. Check that your gutters and drainage can move that much water away from the roof.

Permits

Who issues roofing permits in Mulberry

Any roof repair or replacement needs a permit, and the permit clock matters. A permit expires if work does not start within 6 months of issue, or if the job sits idle for a full 6 months at any point. Ask the building office about any local review before work begins.

On larger projects, Florida mandates that a Notice of Commencement be recorded and displayed on site before the first inspection takes place. Without one, you may end up paying twice for the same work.

Questions

Mulberry roofing questions

What is the 25% roof rule in Florida?

The 25 percent rule caps the share of a roof that can be repaired or replaced within 12 months, and exceeding that cap means the entire roof must meet current code. No more than 25 percent of the roof area can be repaired or replaced unless the entire roof system is replaced. A roof built to the 2007 Florida Building Code or later gets an exception that limits the requirement to the repaired part. Confirm the rule for your roof with the Mulberry building office or your insurer.
