Gutter and downspout size for Green Valley rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Green Valley the five-minute rain expected about once in ten years falls at 6.13 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,170 square feet of roof and one 3-by-4-inch downspout about 2,350, 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 49 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 Green Valley
