When to clean gutters in Marietta

The first fall frost comes around November 7 in a typical year here, and the last spring frost around March 27 (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 Marietta rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Marietta the five-minute rain expected about once in ten years falls at 7.97 inches an hour (NOAA Atlas 14 Volume 9). At that rate one 2-by-3-inch downspout drains about 900 square feet of roof and one 3-by-4-inch downspout about 1,810, 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 Marietta

Half the homes in Marietta were built by 1986, 35% 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.

47% of households own their home, and 44% of homes are detached houses, 12% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in Georgia

Georgia does not require a state contractor license for gutter work: the licensing board lists “Gutters and Downspouts” among the traditional specialty trades, which under O.C.G.A. § 43-41-17 need no residential or general contractor license when the work stays within the specialty. With no state license to look up, ask for proof of liability insurance, the city or county business license, and a written quote.
