When to clean gutters in Spearfish
The first fall frost comes around October 2 in a typical year here, and the last spring frost around May 12 (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.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Spearfish rain
What overwhelms a gutter is a burst, not a season. In Spearfish the five-minute rain expected about once in ten years falls at 6.61 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 2,180, 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.
Spearfish averages about 71 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 Spearfish
Half the homes in Spearfish were built by 1990, 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.
48% of households own their home, and 42% 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.
