Gutters in Lake Wales, FL
In a 10-year storm, five minutes of rain in Lake Wales falls at 9.08 inches an hour. That burst, not the daily total, sets the size your gutters need. Your gutters, downspouts and the spot where they drain all have to handle it.

Our workSizing for Lake Wales rain
How much water your gutters must carry
The number that matters most is the short burst, not the daily total. A 10-year, five-minute downpour here runs at 9.08 inches an hour, and a 100-year one reaches 12.1. Over an hour, a 10-year storm drops 2.8 inches.
IllustrationIllustration: downpour no gutter
The plumbing code sizes horizontal gutters from roof flow. A 6 inch half-round at 1/8 inch per foot slope carries 110 gallons a minute, about 49 percent more than a 5 inch at the same slope. A 6 inch gutter is the safer size for a larger roof plane here.
- Downspouts: a 3 by 4 1/4 inch or 4 inch round leader carries 192 gallons a minute.
- Add half the area of a wall that sheds rain onto the roof when sizing its gutters.
- Pitched roofs need a larger design area than flat plan area.
Discharge rules
Drainage for Lake Wales lots near lakes
Run each outlet at least 1 foot from the house wall. Underground piping, tail extensions or splash blocks all satisfy the code. Keep the outlet clear so water does not return toward the foundation.
The median Lake Wales home was built in 1991, so many of these roofs and gutter runs are likely 30 years old or more. Check hangers, joints and downspout outlets on older systems.
Lake Wales sits among lakes, and Polk County holds 10.5 percent water by area, so low spots and drainage paths matter. Check that water leaves the lot rather than pooling beside the house.
Keeping gutters clear
Leaves, trees and cleaning schedule
Under oaks, clean gutters after the spring leaf drop and pollen season, before the June to September storm season, and after the autumn pine-needle peak. Heavy canopy means more frequent cleaning.
Blocked gutters in Lake Wales can let water reach the roof edge, fascia and foundation during the June to September rains. Inspect gutters and downspouts for granules and debris, which can signal roof wear.

Where should downspouts drain in Lake Wales?
Make sure each downspout empties no closer than 1 foot away from the side of the building. The rule comes from the Florida Building Code residential section on termite protection. Lake Wales is in Polk County, where the county holds 10.5 percent water by area, so check that the outlet drains away from the house.

How often should I clean gutters under oaks in Lake Wales?
Plan on at least two cleanings a year, and extra ones under heavy trees. A practical schedule is after the spring oak leaf drop and pollen season, before the June to September storm season, and after the autumn pine-needle peak. Tower Hill Insurance Group recommends spring and fall cleaning, with more when trees overhang. Polk County's storm season runs June to September, so time the fall cleaning before it.
