Gutters in Juno Beach, FL

Juno Beach gets about 72.19 inches of rain in a normal year, more than the West Palm Beach airport records. That total is spread across a long wet season, and the sharpest test for a gutter is the short burst. In a 10-year storm, the rain can fall at 10.6 inches an hour over five minutes, according to NOAA Atlas 14. Gutters and downspouts that look adequate on a calm day can overflow on that kind of hour.

Rain and sizing

How much water Juno Beach gutters have to carry

The same storm gives 3.32 inches an hour over a full hour and 9.24 inches across 24 hours in a 10-year event. A gutter does not have to hold a day of rain, but it has to pass the peak minutes. Juno Beach gets about 72.19 inches of rain in a normal year, well above the West Palm Beach airport total of 61.75 inches. That is about 10.4 inches more a year.

The median Juno Beach home was built in 1989, which suggests many of the gutters on these houses are original and decades old. Sizing starts from how much water the roof sends down. For a 5-inch half-round at a slope of 1/8 inch per foot, the code table gives 74 gallons per minute, and a 6-inch gives 110. Downspouts are rated too: a 3-inch round carries 92 gallons per minute and a 4-inch round carries 192. At the same slope, a 6-inch gutter moves roughly 49 percent more water than a 5-inch one.

Where the water goes

Downspout placement and the one-foot rule

Under the residential code, buildings with eaves projecting less than 6 inches need gutters with downspouts. Each downspout must empty at least 1 foot out from the sidewall. Water that drops at the foundation can soak the soil beside the slab or pool at the base of a wall. Underground piping, tail extensions and splash blocks all meet the rule, so choose the one that carries the water farthest from the wall on your lot.

Leaves matter here as well. Southern live oaks shed leaves and litter in spring, and the statewide pollen season peaks in March and April. Clean gutters at least twice a year, and more often under heavy trees. About 68.6 percent of occupied homes here are owner-occupied, so the cleaning usually falls to the homeowner. A clogged gutter loses its capacity fast, so the cleaning schedule is part of the sizing.

Rain on your roof

Preset: 9.24 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Juno Beach).

11,513 gallons run off that roof, all of it toward the gutters and downspouts.

What size gutter does Juno Beach need?

The plumbing code sizes gutters from the roof's flow. A 5-inch half-round at a slope of 1/8 inch per foot carries 74 gallons per minute. A 6-inch carries 110. The same code gives a 3-inch round downspout 92 gallons per minute. Your roof size and the number of downspouts decide the final choice, so have it measured before ordering.

How far from the wall must a downspout discharge?

Each downspout in Juno Beach must discharge at least 1 foot from the building sidewall, under the Florida Building Code. The discharge can go through underground piping, a tail extension or a splash block. Water that lands at the foundation can soak the soil beside the slab, so pick the option that carries it farther away on your lot.

How often should gutters be cleaned in Juno Beach?

Clean gutters at least twice a year, and more often if trees overhang the roof. Southern live oaks shed leaves and litter, and the statewide pollen season runs January to June, peaking in March and April. In Juno Beach, where 57.9 percent of residents are 65 or older, a yearly ladder trip is a real safety question, so schedule cleaning before the June to November storm season.
