Gutters in Rockledge, FL
In a 10-year storm, five minutes of rain in Rockledge falls at 10.3 inches an hour. Gutters sized for average rain can overflow in the first minutes of a summer storm and pour water against the foundation of a Rockledge home. A 100-year burst reaches 14.5 inches an hour, so the design basis matters.

Our workRainfall and sizing
How Rockledge rain sizes your gutters
The rainfall numbers for Rockledge are the starting point. A 1-hour rain in a 10-year storm falls at 3.06 inches an hour, and a 100-year storm reaches 4.33. A 24-hour storm can drop 7.46 inches in a 10-year event and 13.1 inches in a 100-year event. The short bursts matter most for gutter sizing.
IllustrationIllustration: two story system
The plumbing code sizes horizontal gutters from the roof surface they drain. A 6-inch half-round gutter at a 1/8 inch per foot slope carries 110 gallons per minute, about 49 percent more than a 5-inch one. Downspouts are rated separately. A 2 1/2 by 3 inch leader carries 92 gallons per minute, and a 3 by 4 1/4 inch leader carries 192.
Pitched roofs need a larger design area than their footprint. The sizing factor rises from 1.05 at a 4 to 5 pitch to 1.30 at a 12 pitch. A steeper Rockledge roof sends more water into the same gutter, so a roof with a higher pitch needs a bigger gutter than a flat-looking one of the same footprint.
Code and drainage
Downspout discharge and where the water goes
Florida's residential code requires gutters with downspouts on buildings with eaves under 6 inches, except at gable end rakes or on a roof above another roof. Each leader must end a set distance out from the wall, and underground piping, tail extensions or splash blocks can all meet that rule.
Rockledge is 11.5 percent water by area, so many lots drain toward low ground. Confirm with the building office how your specific lot is graded before you decide where downspouts should discharge.
Trees and upkeep
Leaves, pollen and cleaning on Rockledge lots
Southern live oaks in Central Florida drop leaves and fruit that become a litter problem in gutters. Oaks, pines and melaleucas are major pollen producers, and the Florida pollen season runs from January to June, peaking in March and April.
- Late spring, once the oaks finish dropping leaves
- Early summer, ahead of the June to September storm season
- Late autumn, after the pine needle fall peaks
Clean more often under heavy tree cover. An insurer recommends cleaning at least twice a year, and clogged gutters can cause water damage and foundation problems.

How far from the house must a Rockledge downspout discharge?
Florida's residential code requires each Rockledge downspout to discharge at least 1 foot (305 mm) from the structure sidewall. Underground piping, tail extensions or splash blocks can all meet that rule. In Rockledge, where a 10-year five-minute burst falls at 10.3 inches an hour, water must leave that 1 foot clearance quickly. The code applies to homes with eaves under 6 inches, except at gable end rakes or on a roof above another roof. Check the Rockledge Building Division if your roof layout differs.

How often should I clean gutters with oaks near my Rockledge home?
In Rockledge, clean after the spring oak leaf drop and before the June to September storm season, then again after the pine needle fall peaks in late autumn. Oaks, pines and melaleucas are major pollen producers here, with the season running from January to June. An insurer recommends at least twice a year, and more often under heavy tree cover. Rockledge's 10-year five-minute burst of 10.3 inches an hour gives clogged gutters little time to clear.

Does my Rockledge home need gutters on a new roof?
In Rockledge, the code requires gutters with downspouts on residential buildings whose eaves project less than 6 inches, except at gable end rakes or where a roof sits above another roof. If your eaves are deeper, gutters are not required by code, though they may still help direct water away from the foundation during a 10.3 inch an hour burst. Rockledge covers 13.2 sq mi, and many of its older homes were built around 1990, so eave depths vary widely across neighborhoods. Confirm the requirement for your exact roof with the Rockledge Building Division.
