Gutter cleaning, repair and new gutters in Gallatin Gateway, MT

When to clean gutters in Gallatin Gateway

The first fall frost comes around September 23 in a typical year here, and the last spring frost around May 23 (median dates, NOAA normals). Plan the fall visit for after the frost, when the trees over the roof have finished dropping, and the spring visit for after the pollen and catkins.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Gallatin Gateway rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Gallatin Gateway the five-minute rain expected about once in ten years falls at 4.52 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 3,190, 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.
