Gutter cleaning, repair and new gutters in Zimmerman, MN

When to clean gutters in Zimmerman

The first fall frost comes around October 5 in a typical year here, and the last spring frost around May 4 (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 Zimmerman rain

What overwhelms a gutter is a burst, not a season. In Zimmerman the five-minute rain expected about once in ten years falls at 7.51 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 960 square feet of roof and one 3-by-4-inch downspout about 1,920, 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.

Zimmerman 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 Zimmerman

Half the homes in Zimmerman were built by 2003, 16% before 1980 (ACS 2020–2024). In a neighborhood that young, many houses still have the gutters the builder put up, and the usual call is a cleaning, a leak or guards rather than a full replacement.

87% of households own their home, and 75% of homes are detached houses, 10% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
