When to clean gutters in San Tan Valley

The first fall frost comes around December 11 in a typical year here, and the last spring frost around February 1 (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 San Tan Valley rain

Gutters are sized for the worst few minutes of a storm, not for the year. In San Tan Valley the five-minute rain expected about once in ten years falls at 4.98 inches an hour (NOAA Atlas 14 Volume 1). At that rate one 2-by-3-inch downspout drains about 1,450 square feet of roof and one 3-by-4-inch downspout about 2,890, 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 Tan Valley is dry by national standards, about 8 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 4.98 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 Tan Valley

Half the homes in San Tan Valley were built by 2006, 2% before 1980 (ACS 2020–2024). With homes this new, the gutters are usually the builder’s originals; keeping them clear matters more than replacing them.

82% of households own their home, and 95% of homes are detached houses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
