Gutter cleaning, repair and new gutters in Knoxville, TN
Knoxville gets about 56 inches of rain in a normal year, and on about 16 days a year an inch or more falls in a single day. The wettest season is winter (December to February), with about 16.3 inches; the driest is fall (September to November), with 11.3. That is about 34,600 gallons a year off each 1,000 square feet of roof, every drop of it through a gutter and a downspout.

Counting days with an inch of rain or more, Knoxville sits near the middle of the 296 places in Tennessee on this site (15.9 a year). By the age of its homes it sits 65th oldest by median year built of the 296 places in Tennessee on this site (half built by 1974). By its first fall frost it sits near the middle of the 296 places in Tennessee on this site (October 28).
When to clean gutters in Knoxville
The first fall frost comes around October 28 in a typical year here, and the last spring frost around April 11 (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 Knoxville rain
What overwhelms a gutter is a burst, not a season. In Knoxville the five-minute rain expected about once in ten years falls at 6.07 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,190 square feet of roof and one 3-by-4-inch downspout about 2,370, 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 Knoxville
Half the homes in Knoxville were built by 1974, 59% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit. 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.
47% of households own their home, and 53% of homes are detached houses, 5% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
