Gutters in Lighthouse Point, FL

NOAA Atlas 14 puts a 5-minute downpour in a 10-year storm at 11 inches an hour in Lighthouse Point. That short burst is the figure your gutters and downspouts must handle. In a city where the median home dates to 1967, many gutter runs are likely original and were sized for lighter rain than this.

Rain and sizing

Sizing gutters for Lighthouse Point downpours

A one-hour total hides the real load. NOAA's 10-year, 1-hour rain here is 3.63 inches, and the 100-year, 24-hour total is 16.7 inches. A gutter sized for the hourly figure can still overflow in a short, intense burst, which is when water hits the eave hardest.

Florida's plumbing code ties gutter size to the flow off the roof. A 6-inch half-round at 1/8 inch per foot carries 110 gallons per minute, and a 5-inch carries 74. By our arithmetic, the 6-inch size moves about 49 percent more water, which counts on a roof facing 11 inches an hour.

Downspouts follow the same logic. A 3 by 4 1/4 inch leader is rated at 192 gallons per minute, and a 2 by 2 inch leader at only 30. Pitched roofs also add the area of any wall that sheds water onto them, so measure the full catchment, not just the footprint.

Code and drainage

Where downspout water ends up on a Lighthouse Point lot

The residential code calls for gutters and downspouts where eaves project less than 6 inches. It also sets the discharge point: at least 1 foot from the sidewall, by buried pipe, tail extension or splash block. With 55.7 percent of housing units here being single-family detached, many lots have a side yard where a short downspout can soak the foundation.

  • Measure from each downspout outlet to the wall, and add an extension where the gap is under 1 foot.
  • Compare each leader's capacity with the roof area it serves.
  • After a hard rain, look for stains or eroded soil where each downspout lets go.

Gutters on Broward homes must also be fastened with corrosion-resistant hardware matched to the gutter material. Confirm the attachment method with the City of Lighthouse Point Building & Zoning office before work starts, since local practice on who may install gutter-only work is not settled in the sources we hold.

Debris and upkeep

Oak leaves, pine needles and a cleaning schedule

Southern live oaks, which spread 60 to 120 feet, shed leaves that litter gutters beneath them. Oak and pine pollen peaks in March and April, and pine needles fall mostly in autumn. A gutter under a dense canopy fills sooner than one in the open.

Broward gets 60.95 inches of rain a year at the Fort Lauderdale airport, and 71.9 percent of it falls from May through October. Clear the gutters in late April or May, before that stretch begins, and again after the autumn needle drop. Insurer guidance also calls for at least two cleanings a year.

Rain on your roof

Preset: 9.42 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Lighthouse Point).

11,737 gallons run off that roof, all of it toward the gutters and downspouts.

Math: square feet × inches × 0.623 gallons.

Questions

Gutters in Lighthouse Point: questions

How hard does it rain on a gutter in Lighthouse Point?

NOAA Atlas 14 puts rainfall here at 11 inches an hour during a 5-minute burst in a storm that comes once every 10 years. A 100-year storm reaches 16.1 inches an hour in that same burst. Gutters rarely fail on total rainfall; they fail when a short, heavy burst exceeds their capacity at the eave. Ask your gutter installer which design rainfall basis they used before accepting a sizing estimate.

How big should my gutters be for a Lighthouse Point roof?

Gutter size depends on roof area and slope, not on the house's footprint alone. Under the plumbing code, a 6-inch half-round at 1/8 inch per foot carries 110 gallons per minute, while a 5-inch carries 74. Pitched roofs add the area of walls that drain onto them. Have the roof area measured before choosing a size, and confirm the sizing basis with the building office.

Where should my downspouts drain in Lighthouse Point?

Florida's residential code requires downspouts to discharge at least 1 foot from the structure sidewall, by underground piping, tail extension or splash block. In Lighthouse Point, where NOAA's 10-year, 1-hour rain is 3.63 inches, a downspout that empties against the foundation can wash out soil and wet the block. Check each discharge point after a heavy rain and look for erosion or standing water. Your building office can confirm the local requirement for a new install.
