Gutters in Kendall West, FL

In a 10-year storm, a 5-minute downpour in Kendall West falls at 10.8 inches an hour, according to NOAA Atlas 14. That is the rate gutters and downspouts here have to move away from the house. Many homes in Kendall West were built around 1986, so many of their gutters are older than the systems now sized for this kind of rain.

Sizing for local rain

How hard rain here sizes gutters and downspouts

Gutter capacity is set by how fast water arrives, not by the yearly total. In Kendall West the short, intense burst matters most. The 1-hour rain in a 10-year storm reaches 3.32 inches an hour, and the 24-hour total reaches 8.29 inches in that same storm.

Florida's plumbing code ties horizontal gutter size to the water coming off the roof. 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 one at the same slope. That gap is large enough to matter on a block with many roof planes.

Downspouts are sized the same way. A 3 by 4 1/4 inch leader carries 192 gallons per minute, and the code adds half the area of any wall that sheds rain onto the roof. Confirm the final size with the Miami-Dade County building office before you order.

Discharge and drainage

Routing outlets on a Kendall West lot

Florida code requires gutters with downspouts on most one- and two-family homes whose eaves project less than 6 inches. Each outlet has to clear the sidewall by at least 1 foot, whether the water runs underground, through a tail extension or onto a splash block.

About 38.3 percent of housing units here are single-family detached homes, and 53.6 percent of occupied homes are owner-occupied. Owners on these lots often control the discharge path, so the downspout outlet is usually their call.

Rain is not a once-a-year event in Miami-Dade County. Miami International Airport records 67.41 inches in a normal year, and 76.6 percent of it falls from May through October. Gutters here carry their heaviest load for half the year.

Debris and upkeep

Leaves, trees and cleaning in Kendall West

Southern live oaks are common in this area and drop fruit and leaves that become litter. Live oaks can grow 60 to 80 feet tall with a 60 to 120 foot spread, so a single tree can drop debris over several gutter runs.

Pollen from oaks peaks in March and April, and a clean gutter is less likely to clog then. Clean gutters at least twice a year, and more often under heavy canopy or during storm season from June through November.

Preset: 8.29 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Kendall West).

10,329 gallons run off that roof, all of it toward the gutters and downspouts.

Where should my downspouts drain in Kendall West?

Florida code requires each downspout to discharge at least 1 foot from the sidewall, using underground piping, tail extensions or splash blocks. In Kendall West, where 29.3 percent of homes sit in buildings with 10 or more units, many roofs shed water across shared walls, so confirm the outlet path with the Miami-Dade County building office.

How often should gutters be cleaned near oak trees in Kendall West?

Clean them in spring and fall, and more often if overhanging trees shed fruit and leaves. In Kendall West, where the median home dates to 1986, an older gutter with loose joints is more likely to hold debris and back up water. Confirm the schedule with the Miami-Dade County building office if your roof has shared walls.
