Gutters in Davie, FL

Davie's 1-hour rain in a 10-year storm falls at 3.46 inches an hour, and the 5-minute burst reaches 10.8. A gutter has to move that water off the roof, along the eave and down the wall without spilling over the edge. Gutters sized for a gentler rain often overflow during the first heavy band of a summer storm.

Sizing for local rain

How rain in Davie sets your gutter size

Gutter sizing starts with the roof area that drains into each run and the rainfall rate. Davie's 25-year burst is 12.7 inches an hour and its 100-year burst is 15.7. A standard 5-inch half-round gutter at 1/8 inch per foot slope carries 74 gallons per minute under the plumbing code table. A 6-inch half-round at the same slope carries 110 gallons per minute, about 49 percent more. That gap is why many older Davie homes with 5-inch runs overflow in heavy rain.

The Florida plumbing code also adds half the area of any vertical wall that sheds rain onto the roof. A two-story wall above a sloped roof can change the gutter size you need. Davie's median home was built in 1989, so many of these roofs are likely to have original gutters that were never sized for this added load.

Code and drainage

Downspouts, discharge and where the water goes

Downspouts also need to be sized. A 3 by 4 1/4 inch or 4-inch round leader carries 192 gallons per minute, while a 2 by 2 inch leader carries only 30. A single small downspout at the end of a long run will back water up into the gutter.

Florida code requires each downspout to discharge at least one foot from the building's sidewall, whether through underground piping, a tail extension or a splash block. Water that lands against the foundation can get under slabs and into crawl spaces. Check that every downspout on your Davie home sends water well away from the wall.

Rain on your roof

Preset: 8.6 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Davie).

10,716 gallons run off that roof, all of it toward the gutters and downspouts.

Questions

Gutters in Davie: questions

What is the 25% roof rule in Florida?

The 25% rule comes from Florida's roofing law and is not a gutter rule. It is about how much of a roof a contractor may replace before the whole roof must meet current code. For a Davie gutter job, the rule matters only if gutter work touches roof decking or edge metal. Ask your building office or your insurer how it applies to your home, since the answer depends on the permit and the scope of work.

How often should gutters be cleaned in Davie?

Clean them at least twice a year, in spring and fall, and more often under heavy trees. Tower Hill Insurance Group recommends the same timing and warns that clogged gutters can cause water damage, mold and foundation problems. Davie's 1-hour burst in a 10-year storm reaches 3.46 inches an hour, so a clogged run overflows fast. Under oaks and pines, add a cleaning after the spring oak leaf drop and another after the autumn pine-needle peak in late November and December.

Do gutters in Davie need hangers that resist storms?

Gutter hangers are a good choice in storm-prone areas. The hidden-hanger maker recommends 16-inch spacing instead of 24 inches on center for added uplift resistance, and aluminum for salt air. Davie sits within Broward County, where Hurricane Irma in 2017 brought widespread tree and power-pole damage across the Miami-Fort Lauderdale metro, so check hanger spacing with your installer.
