Gutter and downspout size for Seneca rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Seneca the five-minute rain expected about once in ten years falls at 8.02 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 900 square feet of roof and one 3-by-4-inch downspout about 1,800, 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 Seneca
Half the homes in Seneca were built by 1971, 72% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. 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.
61% of households own their home, and 92% of homes are detached houses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
