When to clean gutters in Sumner

Gutter and downspout size for Sumner rain
What overwhelms a gutter is a burst, not a season. In Sumner the five-minute rain expected about once in ten years falls at 7.86 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 920 square feet of roof and one 3-by-4-inch downspout about 1,830, 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.
Sumner averages about 41 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 Sumner
Half the homes in Sumner were built by 1946, 89% 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. 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.
78% of households own their home, and 80% of homes are detached houses, 2% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
