Gutters in Deerfield Beach, FL

In a 10-year storm, rain in Deerfield Beach can fall at 10.9 inches an hour for five minutes. Your gutters and downspouts have to carry that peak away from the roof. Undersized gutters overflow in exactly these moments, and the water ends up against your foundation, not in the drain.

Sizing for local rain

How much water your gutters have to move

Florida code sizes gutters by flow from the roof surface, not by guesswork. For a 6-inch half-round gutter at 1/8 inch per foot slope, the code's capacity is 110 gallons per minute. A 5-inch gutter at the same slope carries 74. That means the wider size handles about 49 percent more water, .

Rain totals here are also heavy over a full day. A 10-year storm drops 9.14 inches of rain across a day, and a 100-year storm drops 16.2 inches. Hourly, a 10-year rain falls at 3.58 inches an hour. Your gutters will rarely see the five-minute peak for long, but they must hold water long enough for the downspouts to clear it.

  • Downspouts of 2 by 3 inches carry about 92 gallons per minute.
  • Downspouts of 3 by 4 inches carry about 192 gallons per minute.
  • Add half the area of any wall that sheds rain onto the roof when you size them.

Code and drainage

Where downspouts must discharge on a Deerfield Beach lot

Only 26.8 percent of housing units here are single-family detached, so many roofs sit on attached or multi-unit buildings where downspouts share tight ground. Florida's residential code requires gutters with downspouts on homes whose eaves project less than 6 inches, except at gable end rakes or where a roof sits above another roof. Each leader must end at least 1 foot from the sidewall, by underground piping, tail extensions or splash blocks.

The median home here was built in 1978, so many original gutter systems are likely well past their prime. Warranties on roofing commonly require positive drainage or exclude water damage that comes from its absence. Check where each leader ends before the next storm, and confirm the discharge with City of Deerfield Beach Building Services if the lot is tight.

Keeping gutters clear

Leaves, pine needles and cleaning schedules

Southern live oaks here are 60 to 80 feet tall, and their leaves are a litter problem in gutters. Pine needles peak from September through November. Pollen from oaks and pines runs January to June, with March and April the peak. Under a heavy canopy, gutters fill faster than the calendar suggests.

A workable rhythm under oaks and pines is a clean after the spring leaf drop, another before the June to September storm season, and one after the autumn needle peak. An insurer's guide recommends at least twice a year, and more often under overhanging trees. Gutter screens tested by Consumer Reports did not stop a severe downpour, so plan on cleaning anyway.

Rain on your roof

Preset: 9.14 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Deerfield Beach).

11,388 gallons run off that roof, all of it toward the gutters and downspouts.

What size gutters do I need in Deerfield Beach?

The code sizes gutters by roof flow and slope. A 6-inch half-round at 1/8 inch per foot carries 110 gallons per minute, about 49 percent more than a 5-inch at the same slope. The right size depends on your roof area, pitch and any wall that sheds water onto the roof. Ask for a sizing calculation that uses the local rainfall figures.

Where must my downspouts drain?

In Deerfield Beach, where a 10-year storm drops 10.9 inches an hour for five minutes, water that lands at the foundation can soak the soil quickly. Florida's residential code requires each downspout to discharge at least 1 foot from the sidewall. You can use underground piping, tail extensions or splash blocks. Gutters are required on homes with eaves under 6 inches, except at gable end rakes or under a roof above another roof.

How often should gutters be cleaned near oak and pine trees?

In Deerfield Beach, southern live oaks reach 60 to 80 feet tall and shed leaves that clog gutters, and pine needles peak from September through November. Clean after the spring oak leaf drop, again before the June to September storm season, and after the autumn needle peak. Under heavy canopy, clean more often. An insurer guide recommends at least twice a year. Check for granules too, since heavy granule loss can signal shingle wear.
