When to clean gutters in Corunna
The first fall frost comes around October 14 in a typical year here, and the last spring frost around May 5 (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.

Gutter and downspout size for Corunna rain
The short, hard downpour is what a gutter is sized for. In Corunna the five-minute rain expected about once in ten years falls at 5.99 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,200 square feet of roof and one 3-by-4-inch downspout about 2,400, 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.
Corunna averages about 38 inches of snow a year (NOAA normals). Snow on a roof brings ice dams: heat escaping from the house melts the snow, and the water refreezes at the cold eave, in the gutter and over it. University of Minnesota Extension puts the cause in the attic, not in the gutter, so a gutter that fills with ice is a symptom; hangers spaced to carry ice and a sound fascia are what the gutter itself needs.
The houses in Corunna
Half the homes in Corunna were built by 1969, 70% 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.
59% of households own their home, and 66% of homes are detached houses, 4% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
