Gutter cleaning, repair and new gutters in Hiawatha, IA

When to clean gutters in Hiawatha

The first fall frost comes around October 12 in a typical year here, and the last spring frost around April 28 (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 Hiawatha rain

What overwhelms a gutter is a burst, not a season. In Hiawatha the five-minute rain expected about once in ten years falls at 7.69 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 940 square feet of roof and one 3-by-4-inch downspout about 1,870, 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 34 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 Hiawatha

Half the homes in Hiawatha were built by 1992, 37% 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.

68% of households own their home, and 54% of homes are detached houses, 9% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
