Gutter cleaning, repair and new gutters in Nampa, ID

When to clean gutters in Nampa

The first fall frost comes around October 13 in a typical year here, and the last spring frost around April 29 (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 Nampa rain

The short, hard downpour is what a gutter is sized for. In Nampa the five-minute rain expected about once in ten years falls at 3.55 inches an hour (NOAA Atlas 14 Volume 12). At that rate one 2-by-3-inch downspout drains about 2,030 square feet of roof and one 3-by-4-inch downspout about 4,060, 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.

Nampa is dry by national standards, about 11 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 3.55 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 Nampa

Half the homes in Nampa were built by 1998, 27% before 1980 (ACS 2020–2024). Most houses here are young enough to have their first gutters, so cleanings, guards and small leaks come up more than replacements.

71% of households own their home, and 75% of homes are detached houses, 4% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in Idaho
