When to clean gutters in San Joaquin
The first fall frost comes around November 26 in a typical year here, and the last spring frost around February 27 (median dates, NOAA normals). Plan the fall visit for after the frost, when the trees over the roof have finished dropping, and the spring visit for after the pollen and catkins.

Gutter and downspout size for San Joaquin rain
What overwhelms a gutter is a burst, not a season. In San Joaquin the five-minute rain expected about once in ten years falls at 1.62 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 4,440 square feet of roof and one 3-by-4-inch downspout about 8,890, 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.
San Joaquin is dry by national standards, about 7 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 1.62 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 San Joaquin
Half the homes in San Joaquin were built by 1985, 40% 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. 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.
33% of households own their home, and 55% of homes are detached houses, 5% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
