When to clean gutters in Glenns Ferry

The first fall frost comes around October 3 in a typical year here, and the last spring frost around May 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 Glenns Ferry rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Glenns Ferry the five-minute rain expected about once in ten years falls at 3.68 inches an hour (NOAA Atlas 14 Volume 12). At that rate one 2-by-3-inch downspout drains about 1,960 square feet of roof and one 3-by-4-inch downspout about 3,910, 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.

Glenns Ferry is dry by national standards, about 10 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 3.68 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 Glenns Ferry

Half the homes in Glenns Ferry were built by 1943, 82% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. 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.

65% of households own their home, and 71% of homes are detached houses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
