When to clean gutters in South Riding

The first fall frost comes around October 24 in a typical year here, and the last spring frost around April 15 (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 South Riding rain

What overwhelms a gutter is a burst, not a season. In South Riding the five-minute rain expected about once in ten years falls at 6.52 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,100 square feet of roof and one 3-by-4-inch downspout about 2,210, 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 South Riding

Half the homes in South Riding were built by 2006, 2% before 1980 (ACS 2020–2024). In a neighborhood that young, many houses still have the gutters the builder put up, and the usual call is a cleaning, a leak or guards rather than a full replacement.

83% of households own their home, and 47% of homes are detached houses, 46% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.

Hiring in Virginia

Virginia requires a Board for Contractors license for any contract over $1,000; gutter work on a home falls under the home improvement specialty (HIC) or the residential building classification. Ask for the license number and class, and look it up before signing.
