Gutter cleaning, repair and new gutters in Derby, CO
A normal year in Derby brings about 15 inches of rain; on roughly 2 of its days, an inch or more comes down at once. The wettest season is summer (June to August), with about 5.6 inches; the driest is winter (December to February), with 1.5. Off a 1,000-square-foot roof, that comes to about 9,500 gallons a year for the gutters to carry.

By the age of its homes it sits 4th oldest by median year built of the 181 places in Colorado on this site (half built by 1958). The first frost here ranks near the middle of the 182 places in Colorado on this site (October 8).
When to clean gutters in Derby
The first fall frost comes around October 8 in a typical year here, and the last spring frost around May 4 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Derby rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Derby the five-minute rain expected about once in ten years falls at 5.36 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,340 square feet of roof and one 3-by-4-inch downspout about 2,690, 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.
Derby averages about 49 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 Derby
Half the homes in Derby were built by 1958, 72% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. 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.
67% of households own their home, and 80% of homes are detached houses, 1% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
