Gutter cleaning, repair and new gutters in Bozeman, MT

When to clean gutters in Bozeman

The first fall frost comes around September 22 in a typical year here, and the last spring frost around May 26 (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 Bozeman rain

The short, hard downpour is what a gutter is sized for. In Bozeman the five-minute rain expected about once in ten years falls at 4.54 inches an hour (NOAA Atlas 14 Volume 12). At that rate one 2-by-3-inch downspout drains about 1,590 square feet of roof and one 3-by-4-inch downspout about 3,170, 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 91 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 Bozeman

Half the homes in Bozeman were built by 1998, 33% 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.

45% of households own their home, and 43% of homes are detached houses, 14% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
