When to clean gutters in Dover

When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Dover rain
What overwhelms a gutter is a burst, not a season. In Dover the five-minute rain expected about once in ten years falls at 6.56 inches an hour (NOAA Atlas 14 Volume 10). At that rate one 2-by-3-inch downspout drains about 1,100 square feet of roof and one 3-by-4-inch downspout about 2,200, 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 39 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 Dover
Half the homes in Dover were built by 1975, 56% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit. 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.
51% of households own their home, and 41% of homes are detached houses, 7% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
