When to clean gutters in Herndon
The first fall frost comes around October 24 in a typical year here, and the last spring frost around April 15 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Herndon rain
The short, hard downpour is what a gutter is sized for. In Herndon the five-minute rain expected about once in ten years falls at 6.58 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,090 square feet of roof and one 3-by-4-inch downspout about 2,190, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.
The houses in Herndon
Half the homes in Herndon were built by 1983, 43% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.
63% of households own their home, and 41% of homes are detached houses, 30% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
