Gutter cleaning, repair and new gutters in Contra Costa Centre, CA

When to clean gutters in Contra Costa Centre

Gutter and downspout size for Contra Costa Centre rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Contra Costa Centre the five-minute rain expected about once in ten years falls at 2.51 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,870 square feet of roof and one 3-by-4-inch downspout about 5,740, 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.
