Gutters are sized for the worst few minutes of a storm, not for the year. In Emerald Lake Hills the five-minute rain expected about once in ten years falls at 3.19 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,260 square feet of roof and one 3-by-4-inch downspout about 4,510, by the rule in the Copper Development Association’s design handbook.

The houses in Emerald Lake Hills
Half the homes in Emerald Lake Hills were built by 1983, 44% 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.
92% of households own their home, and 99% of homes are detached houses, 1% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
