When to clean gutters in Winthrop Harbor
The first fall frost comes around October 21 in a typical year here, and the last spring frost around April 30 (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.

Gutter and downspout size for Winthrop Harbor rain
The short, hard downpour is what a gutter is sized for. In Winthrop Harbor the five-minute rain expected about once in ten years falls at 6.96 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,030 square feet of roof and one 3-by-4-inch downspout about 2,070, 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.
Winthrop Harbor averages about 36 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 Winthrop Harbor
Half the homes in Winthrop Harbor were built by 1978, 53% 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.
86% of households own their home, and 91% of homes are detached houses, 1% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
