Rainfall and sizing

Sizing Jensen Beach gutters for a 10-year burst

A 1-hour rain in a 10-year storm falls at 3.12 inches an hour here. The 24-hour total for that same storm is 7.51 inches. A gutter that handles the short burst can still overflow during a long soaking rain, so both numbers matter.

Illustration: downpour with gutter

The state plumbing code sizes horizontal gutters from the roof surface flow. Running at 1/8 inch of fall per foot, a 6-inch half-round gutter moves 110 gallons a minute, whereas a 5-inch model handles 74. By our arithmetic, the 6-inch size carries about 49 percent more water, which is the margin a burst like this needs.

  • Check the slope: gutters must fall toward the downspout to drain.
  • Compare the gutter size to the roof area it drains.
  • Count any wall that sheds rain onto the roof as part of that area.

Discharge rules

Downspouts and where the water goes on Jensen Beach lots

Florida's residential code requires downspouts on buildings with eaves under 6 inches, and each downspout must discharge at least 1 foot from the sidewall. On a lot here, that means water leaves by underground pipe, a tail extension or a splash block, not against the foundation.

Leader size also matters. A 3 by 4 1/4 inch downspout is rated for 192 gallons per minute, while a 2 by 2 inch one carries only 30. Pick the leader to match the gutter it drains, not the other way around.

Debris and upkeep

Leaves, oak litter and cleaning Jensen Beach gutters

Live oaks stay partly green through winter and shed debris that tends to clog gutters down here. Here, oaks are among the heaviest pollen producers during the stretch from January through June. Gutters clogged by leaves and pollen lose capacity right when the June through September storm season begins.

According to Tower Hill Insurance Group, gutters should be cleaned no less than twice yearly, and more frequently when trees hang over the roof or storms roll through often. A practical rhythm for a yard under oaks is after the spring leaf drop, before storm season, and after the autumn pine-needle peak.

Do gutters in Jensen Beach have to have downspouts?

Under Florida's residential code, buildings with eaves extending under 6 inches need gutters and downspouts, though gable end rakes and roofs that sit above another roof are excepted. Every downspout has to release water at least 1 foot away from the sidewall. Confirm your building's eave depth and local requirements with the Martin County Building Department, which issues roof permits for Jensen Beach.

How often should I clean gutters near oak trees in Jensen Beach?

Tower Hill Insurance Group recommends cleaning gutters at least twice a year, typically in spring and fall, and more often under overhanging trees. In Jensen Beach, pollen season runs January to June, and southern live oaks drop litter. Clean after the spring oak leaf drop and before the June through September storm season that Martin County sees most years.
