Gutter cleaning, repair and new gutters in Westminster, CO

When to clean gutters in Westminster

The first fall frost comes around October 11 in a typical year here, and the last spring frost around May 2 (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 Westminster rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Westminster the five-minute rain expected about once in ten years falls at 5.34 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,350 square feet of roof and one 3-by-4-inch downspout about 2,700, 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.

Westminster averages about 45 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.

Westminster is dry by national standards, about 15 inches in a normal year, but much of the rain that does come can arrive in short, hard storms: the five-minute downpour expected once in ten years still runs at 5.34 inches an hour. Where gutters are used here, the job is moving that burst away from the foundation, and keeping a dry season’s dust and debris from blocking the first storm.

The houses in Westminster

Half the homes in Westminster were built by 1987, 35% 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.

64% of households own their home, and 56% of homes are detached houses, 10% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
