When to clean gutters in St. John

The first fall frost comes around October 20 in a typical year here, and the last spring frost around April 23 (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 St. John rain

What overwhelms a gutter is a burst, not a season. In St. John the five-minute rain expected about once in ten years falls at 7.31 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 980 square feet of roof and one 3-by-4-inch downspout about 1,970, 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 St. John

Half the homes in St. John were built by 2002, 24% 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.

98% of households own their home, and 85% of homes are detached houses, 13% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
