When to clean gutters in Jefferson

Gutter and downspout size for Jefferson rain
What overwhelms a gutter is a burst, not a season. In Jefferson the five-minute rain expected about once in ten years falls at 7.97 inches an hour (NOAA Atlas 14 Volume 8). 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.
With about 32 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 Jefferson
Half the homes in Jefferson were built by 1958, 77% 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 74% of homes are detached houses, 5% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
