Gutter and downspout size for Sully rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Sully the five-minute rain expected about once in ten years falls at 8.05 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 890 square feet of roof and one 3-by-4-inch downspout about 1,790, 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 31 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 Sully
Half the homes in Sully were built by 1965, 82% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.
90% of households own their home, and 90% of homes are detached houses, 5% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
