Gutter cleaning, repair and new gutters in Mount Sinai, NY
A normal year in Mount Sinai brings about 46 inches of rain; on roughly 12 of its days, an inch or more comes down at once. The wettest season is spring (March to May), with about 11.8 inches; the driest is fall (September to November), with 11.0. Off a 1,000-square-foot roof, that comes to about 28,500 gallons a year for the gutters to carry.

When to clean gutters in Mount Sinai
The first fall frost comes around November 7 in a typical year here, and the last spring frost around April 4 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.

Gutter and downspout size for Mount Sinai rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Mount Sinai the five-minute rain expected about once in ten years falls at 7.51 inches an hour (NOAA Atlas 14 Volume 10). At that rate one 2-by-3-inch downspout drains about 960 square feet of roof and one 3-by-4-inch downspout about 1,920, 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.
Mount Sinai 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 Mount Sinai
Half the homes in Mount Sinai were built by 1985, 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.
97% of households own their home, and 83% of homes are detached houses, 10% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
