Gutter and downspout size for Hollister rain
What overwhelms a gutter is a burst, not a season. In Hollister the five-minute rain expected about once in ten years falls at 2.24 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 3,210 square feet of roof and one 3-by-4-inch downspout about 6,430, 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.
Hollister is dry by national standards, about 14 inches in a normal year, but much of the rain that does come can arrive in short, hard storms: the five-minute downpour expected once in ten years still runs at 2.24 inches an hour. Where gutters are used here, the job is moving that burst away from the foundation, and keeping a dry season’s dust and debris from blocking the first storm.
The houses in Hollister
Half the homes in Hollister were built by 1989, 33% 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.
65% of households own their home, and 80% of homes are detached houses, 3% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
