When to clean gutters in Flagstaff
The first fall frost comes around September 28 in a typical year here, and the last spring frost around June 4 (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 Flagstaff rain
What overwhelms a gutter is a burst, not a season. In Flagstaff the five-minute rain expected about once in ten years falls at 5.33 inches an hour (NOAA Atlas 14 Volume 1). At that rate one 2-by-3-inch downspout drains about 1,350 square feet of roof and one 3-by-4-inch downspout about 2,700, 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.
Flagstaff averages about 90 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 Flagstaff
Half the homes in Flagstaff were built by 1992, 28% 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.
42% of households own their home, and 42% of homes are detached houses, 9% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
