How often should gutters be cleaned in Charlotte?
It follows what is overhead, not the calendar. Under willow oak and pine, twice a year covers most homes - the spring catkin drop in Mar and Apr and the acorn drop from Sep to Nov, with pine adding needles in between. A roof with little canopy may need less; under sweetgum, add a check once the gumballs finish in Apr.
