Counting days with an inch of rain or more, North Potomac sits among the fewest heavy-rain days of the 329 places in Maryland on this site (10.5 a year).

By its first fall frost it sits near the middle of the 329 places in Maryland on this site (November 6).
When to clean gutters in North Potomac
The first fall frost comes around November 6 in a typical year here, and the last spring frost around April 1 (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 North Potomac rain
What overwhelms a gutter is a burst, not a season. In North Potomac the five-minute rain expected about once in ten years falls at 6.54 inches an hour (NOAA Atlas 14 Volume 2). 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 31 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 North Potomac
Half the homes in North Potomac were built by 1988, 15% 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.
83% of households own their home, and 67% of homes are detached houses, 23% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
Hiring in Maryland
Maryland requires a Maryland Home Improvement Commission license for home improvement work of any amount, gutters included, and a contractor may not take a deposit of more than one third of the contract price (Business Regulation § 8-617). Look the license up before signing, and keep the deposit to one third or less.
