Gutter cleaning, repair and new gutters in Oro Valley, AZ

When to clean gutters in Oro Valley

The first fall frost comes around November 11 in a typical year here, and the last spring frost around April 2 (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.

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

Gutter and downspout size for Oro Valley rain

What overwhelms a gutter is a burst, not a season. In Oro Valley the five-minute rain expected about once in ten years falls at 5.96 inches an hour (NOAA Atlas 14 Volume 1). At that rate one 2-by-3-inch downspout drains about 1,210 square feet of roof and one 3-by-4-inch downspout about 2,420, 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.

Oro Valley is dry by national standards, about 12 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 5.96 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.
