When to clean gutters in Andover
The first fall frost comes around October 2 in a typical year here, and the last spring frost around May 5 (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 Andover rain
The short, hard downpour is what a gutter is sized for. In Andover the five-minute rain expected about once in ten years falls at 7.40 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 970 square feet of roof and one 3-by-4-inch downspout about 1,950, 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.
Andover averages about 44 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 Andover
Half the homes in Andover were built by 1993, 25% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look.
94% of households own their home, and 92% of homes are detached houses, 5% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
