Gutter and downspout size for Columbia rain
What overwhelms a gutter is a burst, not a season. In Columbia the five-minute rain expected about once in ten years falls at 7.70 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 940 square feet of roof and one 3-by-4-inch downspout about 1,870, 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 Columbia
Half the homes in Columbia were built by 1993, 32% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit.
49% of households own their home, and 53% of homes are detached houses, 6% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
