Sizing the system

Sizing Polk City gutters for a 9.1-inch burst

Rain intensity is the number that drives gutter size, not the yearly total. Here a one-hour rain in a 10-year storm reaches 2.8 inches an hour, and a 100-year storm reaches 3.82. Over 24 hours, a 10-year storm drops 6.12 inches and a 100-year storm drops 10.7 inches.

Code sizing starts from how much water the roof sends into each run. A 6-inch half-round at 1/8 inch per foot slope carries 110 gallons per minute, about 49 percent more than a 5-inch at the same slope. Downspout capacity is set separately, with a 3 by 4 1/4 inch or 4-inch round leader carrying 192 gallons per minute.

Roof area drained into the gutter also depends on pitch and nearby walls. A 6-inch half-round serves far less roof on a five-minute design basis than on a one-hour basis, so confirm the sizing method with the building office or your contractor before you choose.

Keeping water off the foundation

Downspout discharge and where the water goes

Florida code requires downspouts to discharge at least one foot from the sidewall. Water that lands next to the foundation can work toward the slab, so check where each downspout ends after heavy rain on a Polk City lot. Water covers 11% of the town's total area, so many lots sit near standing water and wet ground.

  • Confirm each downspout ends at least one foot from the wall.
  • Use extensions or buried piping on lots where water pools near the house.
  • Check that gutter seams are lapped, soldered or caulked, and that fasteners are corrosion resistant.

Maintenance schedule

Leaves, pollen and cleaning on oak-lined lots

Southern live oaks are semi-evergreen and drop a steady litter, and they can grow 60 to 80 feet tall with a 60 to 120 foot spread. Oaks and pines are major pollen producers here, with the season running January to June and peaking in March and April. Needle drop from pines in town peaks in the autumn, the same stretch when storm rains are tapering off.

A sensible cleaning rhythm under these trees is after the spring oak leaf drop and pollen in late April and May, before the June to September storm season, and after the autumn pine-needle peak in late November and December. Clean more often under heavy canopy.

Rain on your roof

Preset: 6.12 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Polk City).

7,626 gallons run off that roof, all of it toward the gutters and downspouts.

Where should my downspouts drain in Polk City?

How often should I clean gutters under oak trees?

Under live oaks in Polk City, clean after the spring leaf drop and pollen in late April and May, before the June to September storm season, and after the autumn needle peak in late November and December. Heavy canopy means more frequent cleaning. Tower Hill Insurance Group advises cleaning at least twice a year, and southern live oaks can reach 60 to 80 feet tall.

Are gutters required on a Polk City home?

Florida code requires gutters with downspouts on buildings whose eaves project less than 6 inches, with exceptions at gable end rakes and where a roof sits above another roof. Most homes in Polk City were built around 2007, so many already have a system. Confirm your home's details with the Polk County building office.
