Gutter and downspout size for Allison rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Allison the five-minute rain expected about once in ten years falls at 8.29 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 870 square feet of roof and one 3-by-4-inch downspout about 1,740, 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.
Allison averages about 32 inches of snow a year (NOAA normals). Snow on a roof brings ice dams: heat escaping from the house melts the snow, and the water refreezes at the cold eave, in the gutter and over it. University of Minnesota Extension puts the cause in the attic, not in the gutter, so a gutter that fills with ice is a symptom; hangers spaced to carry ice and a sound fascia are what the gutter itself needs.
The houses in Allison
Half the homes in Allison were built by 1956, 80% 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.
72% of households own their home, and 88% of homes are detached houses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
