Local know-how

Sizing a Titusville gutter for a 10.6-inch burst

The plumbing code rates gutters in gallons per minute. At a slope of 1/8 inch per foot, a 5-inch half-round carries 74 gpm and a 6-inch carries 110, about 49% more. One gallon per minute drains about 96 square feet of roof for each inch an hour of rain, so the rain rate you design for changes the answer.

Run the numbers at 10.6 inches an hour and a 6-inch half-round handles roughly 1,000 square feet of roof plan area. At the plumbing code's 100-year, 1-hour rate for the same point, 4.37 inches an hour, it handles about 2,420. That is arithmetic on NOAA and code figures, not a code rule, but it shows why a gutter that looks big enough can still spill in a July storm.

Downspouts matter as much as the trough. A 3-inch round leader carries 92 gpm and a 4-inch round carries 192. The code also wants each downspout to discharge at least 1 foot from the wall, through pipe, an extension or a splash block.

Upkeep

Pollen, needles and older fascia in Titusville

June through August brings 41% of the year's rain at Titusville's station, so go into summer with clear gutters. UF/IFAS puts Florida's pollen season from January to June, peaking in March and April, with oaks and pines among the heavy producers, and pine needles fall hardest from September through November. Under oaks and pines, a sensible rhythm is a cleaning after the spring leaf drop, one before the June storms and one after the autumn needle fall.

Check the board behind the gutter, too. On a house built before 1980, as 45.5% of Titusville's are, the fascia may need work before new gutters can hang tight, and Florida's contractor rules let a roofer repair or replace fascia during a roof repair or replacement.

Gutters move roof water; they do not change a lot's flood zone. Titusville takes part in FEMA's Community Rating System and keeps its floodplain administrator in the Building Department, so that is the office to ask about flood rules for your address.

Questions

Gutters in Titusville: questions

What size gutters does a Titusville house need?

Size them to the roof and the rain, not to habit. At 10.6 inches an hour, the 10-year, 5-minute rate at Melbourne, the nearest Atlas 14 point to Titusville in our data, a 5-inch half-round at 1/8-inch slope drains about 670 square feet of roof plan area and a 6-inch about 1,000. Sizing charts also scale the roof area up for pitch, by a factor of 1.05 to 1.30 as the roof gets steeper.

How often should Titusville gutters be cleaned?

At least twice a year, spring and fall, as one Florida home insurer's guidance recommends, and more often under trees or after storms. In Titusville, time one cleaning before June: the station's June-August rain averages 22.44 inches, and a clogged gutter in a summer storm can send water into the fascia, the soffits and the foundation. Under pines, add a pass after the autumn needle drop.

Where should downspouts drain on a Titusville lot?

At least 1 foot from the wall, by underground pipe, a tail extension or a splash block; the Florida Building Code puts that rule in its termite-protection section. Beyond that, send the water where the lot drains away from the house. Water covers 14.8% of Titusville's area, and if your lot is in a mapped flood zone, the city's floodplain administrator can tell you what applies before you pipe or regrade.
