Gutter cleaning, repair and new gutters in Big Sky, MT

When to clean gutters in Big Sky

The first fall frost comes around September 4 in a typical year here, and the last spring frost around June 16 (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 Big Sky rain

The short, hard downpour is what a gutter is sized for. In Big Sky the five-minute rain expected about once in ten years falls at 4.16 inches an hour (NOAA Atlas 14 Volume 12). At that rate one 2-by-3-inch downspout drains about 1,730 square feet of roof and one 3-by-4-inch downspout about 3,460, 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 45 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 Big Sky

Half the homes in Big Sky were built by 2000, 17% 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.

86% of households own their home, and 51% of homes are detached houses, 20% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
