When to clean gutters in Lyons
The first fall frost comes around October 5 in a typical year here, and the last spring frost around May 7 (median dates, NOAA normals). Plan the fall visit for after the frost, when the trees over the roof have finished dropping, and the spring visit for after the pollen and catkins.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Lyons rain
What overwhelms a gutter is a burst, not a season. In Lyons the five-minute rain expected about once in ten years falls at 5.44 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,320 square feet of roof and one 3-by-4-inch downspout about 2,650, 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 40 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 Lyons
Half the homes in Lyons were built by 1998, 21% 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.
80% of households own their home, and 83% of homes are detached houses, 8% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
