When to clean gutters in Shenandoah

The first fall frost comes around November 26 in a typical year here, and the last spring frost around February 28 (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 Shenandoah rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Shenandoah the five-minute rain expected about once in ten years falls at 10.00 inches an hour (NOAA Atlas 14 Volume 9). At that rate one 2-by-3-inch downspout drains about 720 square feet of roof and one 3-by-4-inch downspout about 1,440, 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.

The houses in Shenandoah

Half the homes in Shenandoah were built by 1989, 25% 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.

76% of households own their home, and 77% of homes are detached houses, 2% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
