Gutters in Dundee, FL
A 5-minute downpour in a 10-year storm falls at 9.06 inches an hour in Dundee. A 100-year storm of the same length falls at 12.1 inches an hour. Gutters sized for ordinary rain can overflow in a few minutes of that. The gutter size, downspout count and discharge point all matter more here than in most towns.

Sizing Dundee gutters for intense burst rain
Florida plumbing code sizes gutters from the roof's flow rate, not from a rule of thumb. For Dundee's 9.06 inch hourly burst, the width and slope of the trough decide how much water it can carry before it spills over the edge. Many Dundee roofs are likely past 25 years old, since the median home dates to 1996, so check what size is hanging on yours now.

Downspouts follow their own table. A 2 by 2 inch leader handles 30 gallons per minute, while a 3 inch round leader handles 92. Add half the area of any wall that sheds rain onto the roof, since that water also reaches the gutter. Dundee's 2.8 inch hourly rate for a 10-year, 1-hour storm shows why one small downspout on a long run often falls short. Mobile homes make up 22 percent of Dundee housing, and their low, wide roofs often shed a lot of water to one corner.
Discharge and placement
Where the water goes after the downspout
Florida code wants each downspout to empty at least 1 foot out from the sidewall. Underground piping, a tail extension or a splash block all meet that. Dundee sits on rolling hills of the Lake Wales Ridge, so on a sloped lot point the discharge downhill and away from the slab, not toward a neighbor or the house. Walk the lot after a heavy rain and check where each downspout lands.
Keeping gutters clear
Leaves, pollen and cleaning in Dundee
Southern live oaks in Central Florida drop leaves and litter, and oaks and pines are major pollen producers. Pollen season runs January through June with peaks in March and April. Needle fall from pines is heaviest in autumn, September through November. A clogged gutter loses capacity fast, so a spring and fall cleaning rhythm fits a Dundee lot with mature trees.
Polk County gets 46.12 inches of rain a year at the Winter Haven airport station and 56.82 inches at Lakeland, with 26.62 inches of that falling June through August. Clean the gutters before that stretch begins. Granules collecting in the gutter are also one sign of an aging shingle roof.
Rain on your roof
Preset: 6.11 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Dundee).
7,613 gallons run off that roof, all of it toward the gutters and downspouts.

Questions
Gutters in Dundee: questions
How much rain falls on a Dundee gutter in a storm?
In a 5-minute burst during a 10-year storm, Dundee gets 9.06 inches of rain an hour. In a 100-year storm, the same burst reaches 12.1 inches an hour. Over 24 hours, a 10-year storm drops 6.11 inches and a 100-year storm drops 10.5 inches. Gutters should be sized to the short, intense burst, not the daily total. Ask a roofer to size the trough and downspouts to that figure.

How many downspouts does a Dundee house need?
The code sets the downspout size from the gutter's flow, so the count depends on roof area, slope and how many wall areas shed rain onto the roof. A 2 by 2 inch leader carries 30 gallons per minute, while a 3 inch round leader carries 92. Florida code requires downspouts wherever eaves project less than 6 inches, with gable rakes and roofs above roofs excepted. A site check gives the count for your house.

Do Dundee gutters need a permit?
Permit rules for gutter work depend on the local building office. Roof permit applications in Dundee go through the Town's Building Department. Dundee has a mix of older and newer housing, and the median home was built in 1996 (margin of error ±5), so many gutter jobs involve existing structures. Confirm with the building department before starting work, since the rules for gutter-only jobs can differ from roof replacements.
