Gutter cleaning, repair and new gutters in Hercules, CA

When to clean gutters in Hercules

Frost is rare in Hercules, and in many years there is none (NOAA normals). With no hard freeze to strip the trees, the fall cleaning follows the leaf drop itself; book it once the trees over the roof are bare, and plan a second visit in spring.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Hercules rain

What overwhelms a gutter is a burst, not a season. In Hercules the five-minute rain expected about once in ten years falls at 2.41 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,990 square feet of roof and one 3-by-4-inch downspout about 5,980, 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.

81% of households own their home, and 59% of homes are detached houses, 19% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
