When to clean gutters in Old Jamestown

The first fall frost comes around November 4 in a typical year here, and the last spring frost around April 2 (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.

Gutter and downspout size for Old Jamestown rain

The short, hard downpour is what a gutter is sized for. In Old Jamestown the five-minute rain expected about once in ten years falls at 7.50 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 960 square feet of roof and one 3-by-4-inch downspout about 1,920, 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.
