When to clean gutters in Kewanee
The first fall frost comes around October 17 in a typical year here, and the last spring frost around April 24 (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 Kewanee rain
What overwhelms a gutter is a burst, not a season. In Kewanee the five-minute rain expected about once in ten years falls at 7.79 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 920 square feet of roof and one 3-by-4-inch downspout about 1,850, 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.
With about 31 inches of snow in a normal year here (NOAA normals), gutters carry ice as well as water. Ice dams start with heat from the house melting roof snow that refreezes at the edge (University of Minnesota Extension); the fix for the dam is in the attic, and the gutter’s part is to be hung strongly enough to take the weight.
The houses in Kewanee
Half the homes in Kewanee were built by 1948, 90% 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.
70% of households own their home, and 83% of homes are detached houses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
