When to clean gutters in Lake St. Louis
The first fall frost comes around October 26 in a typical year here, and the last spring frost around April 10 (median dates, NOAA normals). Booking the fall cleaning after the first frost, once the trees over the roof are bare, catches the season’s drop in one visit; the spring cleaning comes after the pollen and catkins are down.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Lake St. Louis rain
What overwhelms a gutter is a burst, not a season. In Lake St. Louis the five-minute rain expected about once in ten years falls at 7.48 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 960 square feet of roof and one 3-by-4-inch downspout about 1,930, 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.
The houses in Lake St. Louis
Half the homes in Lake St. Louis were built by 1999, 19% before 1980 (ACS 2020–2024). In a neighborhood that young, many houses still have the gutters the builder put up, and the usual call is a cleaning, a leak or guards rather than a full replacement.
75% of households own their home, and 67% of homes are detached houses, 12% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
