Gutter cleaning, repair and new gutters in Keystone, CO

When to clean gutters in Keystone

The first fall frost comes around September 19 in a typical year here, and the last spring frost around June 6 (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 Keystone rain

The short, hard downpour is what a gutter is sized for. In Keystone the five-minute rain expected about once in ten years falls at 3.77 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,910 square feet of roof and one 3-by-4-inch downspout about 3,820, 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 116 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 Keystone

Half the homes in Keystone were built by 1991, 27% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look.

21% of households own their home, and 16% of homes are detached houses, 5% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in Colorado
