Gutters in East Lake-Orient Park, FL
A 5-minute downpour in a 10-year storm falls at 9.71 inches an hour in East Lake-Orient Park. That is the number that decides whether your gutters keep up when the sky opens. Gutter sizing here should start from that burst, not from an average rain day.

Sizing for local rain
How much rain your gutters must carry here
Horizontal gutters here must be sized to the flow coming off the roof, and a short, intense burst matters more than the daily total. Tampa International Airport normals show about 49.48 inches a year, and about 61 percent of that falls June through September. Expect your gutters to face many heavy afternoon storms each summer.
IllustrationIllustration: downpour with gutter
The code table gives a 6-inch half-round gutter at 1/8 inch per foot a capacity of 110 gallons per minute. At the same slope, a 5-inch half-round gutter handles 74 gallons per minute. Going from 5 inches to 6 inches adds about 49 percent of capacity, by our arithmetic. For a roof that drains a lot of area into one run, that step is worth asking your installer about.
Pitch changes the roof area each gutter has to serve. A roof at 6 to 8 inches of rise per foot uses a factor of 1.10 on its plan area under the sizing method, and a 12-in-12 roof uses 1.30. Measure your roof's pitch before you ask for a size.
Discharge rules
Downspouts and where the water goes
Under Florida's residential code, the downspout outlet must sit no closer than 1 foot to the building's sidewall. Underground pipe, tail extensions and splash blocks are all options for meeting that distance. Water that lands against your block wall or slab is the water that finds the foundation.
Downspout capacity is its own limit. A round leader measuring 3 by 4 1/4 inches, or 4 inches across, moves 192 gallons per minute. By contrast, a 2 by 2 inch leader manages just 30 gallons per minute. A large gutter feeding a small downspout will overflow at the joint where the two meet.
- Walk the perimeter and make sure every downspout discharges at least 1 foot out from the wall.
- Check that leaders are sized to the gutter run they serve.
- Look for overflow stains at the corners and downspout joints after a storm.
Debris and upkeep
Leaves, needles and cleaning your gutters
Southern live oaks in this part of the county drop leaves that litter gutters, and oaks and pines are major pollen sources from January through June. The heaviest pine needle drop usually runs from September into November. A sensible schedule is after the spring oak drop, before the June through September storm season, and after the autumn needle peak.
Tower Hill Insurance Group recommends clearing gutters a minimum of two times each year, with extra passes when trees hang over the roofline. When gutters stay blocked, they may lead to water damage, mold growth, roof problems and trouble with the foundation. A fine-mesh screen helps, but Consumer Reports found even the top-scoring screen was only middling at handling a severe downpour, so screens do not replace cleaning.

What size downspout does a gutter here need?
The code table lists a 2 by 2 inch leader at 30 gallons per minute and a 3 by 4 1/4 inch or 4-inch round leader at 192 gallons per minute. Match the downspout to the gutter run it drains. A 6-inch half-round gutter carries 110 gallons per minute at 1/8 inch per foot slope, so its downspouts must carry at least that much.

How far from the wall must a downspout discharge?
Florida's residential code says at least 1 foot from the sidewall, using underground piping, tail extensions or splash blocks. Water that pools at the foundation can reach the slab and block wall, so check the discharge point after each storm. For questions about your specific home, confirm with the Hillsborough County building office, which issues permits for the 11,647 housing units in this area.

How often should I clean gutters near oak trees here?
Clean gutters at least twice a year, and more often if oaks overhang your roof or storms are frequent. Southern live oaks drop leaves that litter gutters, so schedule one cleaning after the spring oak drop and another before the June through September storm season. Tower Hill Insurance Group advises this same schedule. Homes in the Florida State Fairgrounds area often sit under mature oaks, so checking gutters after heavy leaf fall keeps water flowing away from your foundation.
