When to clean gutters in Bull Run

The first fall frost comes around October 27 in a typical year here, and the last spring frost around April 12 (median dates, NOAA normals). Booking the fall cleaning after the first frost, once the trees over the roof are bare, catches the season’s drop in one visit; the spring cleaning comes after the pollen and catkins are down.

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

Gutter and downspout size for Bull Run rain

The short, hard downpour is what a gutter is sized for. In Bull Run the five-minute rain expected about once in ten years falls at 6.47 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,110 square feet of roof and one 3-by-4-inch downspout about 2,230, 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 Bull Run

Half the homes in Bull Run were built by 1993, 19% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look.

35% of households own their home, and 5% of homes are detached houses, 31% 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.
