Gutters in Miami Springs, FL

In a 10-year storm, rain in Miami Springs can fall at 10.9 inches an hour over five minutes, according to NOAA Atlas 14 for this town. A 25-year storm reaches 12.8 inches an hour, and a 100-year storm reaches 15.8. Gutters here have to carry water at that rate, not the rate of a typical afternoon shower.

Sizing for local rain

Calculating the volume of runoff your gutters have to handle in Miami Springs

Gutter sizing starts with the rain rate, and the rate here is high. The 1-hour rain in a 10-year storm falls at 3.39 inches an hour, and a 24-hour storm of that size drops 8.51 inches. Those are the local numbers a gutter has to survive.

The plumbing code sizes horizontal gutters from the flow off the roof, and a 6-inch half-round gutter at 1/8 inch per foot slope carries about 110 gallons per minute. By our arithmetic, that is about 49 percent more than a 5-inch gutter at the same slope. Moving up one size is a cheap way to add margin on a Miami Springs roof.

Miami-Dade's 1991 to 2020 normal rainfall at Miami International Airport is 67.41 inches a year, and 76.6 percent of it falls May through October. Gutters that work in a dry month can overflow in the wet season, so the wet-season rain is the figure to design for.

Code and drainage

Choosing a discharge point for downspouts on a Miami Springs property

Florida's building code requires downspouts on buildings whose eaves project less than 6 inches, and each downspout must send water at least 1 foot away from the sidewall. With heavy rain, a downspout that dumps at the foundation can soak the footing of a 1958 house in a way a shower never would.

The code allows discharge through underground piping, tail extensions or splash blocks. Use whichever keeps the water moving away from the house on your lot. Under a warranty, many roofers require positive drainage, so check how your gutters discharge before a roof job.

  • Confirm each downspout ends at least 1 foot from the sidewall.
  • Check that the leader size matches the roof area it drains.
  • Look for water pooling at the base of the wall after a storm.

Debris and upkeep

Leaves, trees and cleaning gutters in Miami Springs

Southern live oaks drop leaves and fruit that become a litter problem, and oaks and pines are major pollen producers in Florida. Pollen peaks in March and April, and the pine-needle fall peaks September through November. A clogged gutter in one of those months can overflow into the first June storm.

Insurers and roofing trade sources advise cleaning gutters at least twice a year, and more often under heavy trees or frequent storms. A sensible rhythm for a canopy lot is late April or May, before the June to September season, and again late November or December. Clogged gutters can cause water damage, mold and foundation trouble.

What size gutter does a Miami Springs roof need?

Size depends on the roof area each gutter drains and the slope. The plumbing code lists a 6-inch half-round gutter at 1/8 inch per foot slope at 110 gallons per minute, and a 5-inch gutter at 74. Going up one size adds about 49 percent capacity, . Confirm the final size with the City of Miami Springs building office before installing.
