Gutter cleaning, repair and new gutters in Oshkosh, WI

The wettest season is summer (June to August), with about 12.0 inches; the driest is winter (December to February), with 4.0.

When to clean gutters in Oshkosh
The first fall frost comes around October 20 in a typical year here, and the last spring frost around April 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 Oshkosh rain
The short, hard downpour is what a gutter is sized for. In Oshkosh the five-minute rain expected about once in ten years falls at 6.59 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,090 square feet of roof and one 3-by-4-inch downspout about 2,190, 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.
Oshkosh averages about 39 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 Oshkosh
Half the homes in Oshkosh were built by 1972, 59% 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.
54% of households own their home, and 55% 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.
