When to clean gutters in Manteca
The first fall frost comes around December 1 in a typical year here, and the last spring frost around February 6 (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 Manteca rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Manteca the five-minute rain expected about once in ten years falls at 2.14 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 3,360 square feet of roof and one 3-by-4-inch downspout about 6,730, 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.
Manteca is dry by national standards, about 13 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 2.14 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.
