Gutter cleaning, repair and new gutters in Chattanooga, TN
A normal year in Chattanooga brings about 55 inches of rain; on roughly 16 of its days, an inch or more comes down at once. The wettest season is winter (December to February), with about 15.3 inches; the driest is fall (September to November), with 12.6. Off a 1,000-square-foot roof, that comes to about 34,100 gallons a year for the gutters to carry.

By house age it falls 74th oldest by median year built of the 296 places in Tennessee on this site (half built by 1975).

When to clean gutters in Chattanooga
The first fall frost comes around November 9 in a typical year here, and the last spring frost around March 24 (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 Chattanooga rain
The short, hard downpour is what a gutter is sized for. In Chattanooga the five-minute rain expected about once in ten years falls at 7.04 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,020 square feet of roof and one 3-by-4-inch downspout about 2,050, 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 Chattanooga
Half the homes in Chattanooga were built by 1975, 56% 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. 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.
53% of households own their home, and 58% of homes are detached houses, 5% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
