Rainfall and sizing

How hard Leisure City rain tests a gutter run

The 5-minute, 10-year rate of 10.5 inches an hour is the figure that matters most for gutters, because short hard bursts overwhelm a gutter before a longer storm does. A 1-hour 10-year rain falls at 3.41 inches an hour, and a 24-hour 10-year storm drops 7.95 inches in total. Your gutter has to carry the burst, not just the daily total.

Miami-Dade County gets most of its rain in the warm season. Between May and October, Miami International Airport receives about 76.6 percent of its 67.41-inch annual normal rainfall, with June the heaviest month at 10.51 inches. Your gutters carry the most water exactly when hurricane season opens on June 1.

Plumbing code sizes horizontal gutters by the flow from the roof surface, using a table of capacities by diameter and slope. By our arithmetic, a 6-inch half-round gutter at 1/8 inch per foot carries 110 gallons per minute, about 49 percent more than a 5-inch size at the same slope. Ask a contractor which design rainfall the sizing uses before you accept a plan.

Downspouts and code

Matching leader size and discharge on a Leisure City lot

Downspouts must be sized to match the gutter they drain. Plumbing table capacities run from 30 gallons per minute for a 2-by-2-inch leader to 192 for a 3-by-4-inch or 4-inch round. Add half the area of any vertical wall that sheds rain onto the roof when you size them, as the plumbing table directs.

Debris and upkeep

Leaves, pollen and cleaning in Leisure City

Southern live oaks shed leaves and fruit that clog gutters, and their canopies can spread 60 to 120 feet. Pollen season runs January to June in Florida, peaking in March and April, and oaks are among the main producers. A simple rhythm is cleaning after the spring pollen and oak drop, before the June through September rain season, and again after the autumn pine-needle peak.

Tower Hill Insurance Group recommends cleaning gutters twice a year, and more often when overhanging trees or frequent storms are part of the picture. Blocked gutters are linked to water damage, mold, roof damage and foundation trouble. A gutter that backs up in a 10-year burst will push water behind the fascia.

Plan for at least 1 foot of clearance between the downspout outlet and the wall, using underground piping, tail extensions or splash blocks. Water that pools against the foundation can reach the house in a storm with 7.95 inches of rain in 24 hours. Check the discharge after every heavy rain.
