What actually falls on Mount Pleasant roofs, and when
The historic core has the substantial mature planting of a town centre that has stood for well over a century, with large hardwoods arching over the older streets and directly above the roofs. The newer edges are open and lightly planted. The debris difference across a few hundred yards is considerable, and it is another reason the older half of the town needs a different cleaning schedule from the newer half.
That is the part national advice cannot tell you. Almost every article on this subject says twice a year, spring and autumn, and books the autumn visit for October. Across this metro that timing is wrong, because the dominant street tree is the willow oak (roughly 200,000 street trees in Charlotte, a significant share of them oak), and willow oak holds its leaves late, dropping through late autumn and into winter rather than in one convenient fortnight. A single clean booked for October happens in the middle of the drop rather than at the end of it.
So under real canopy the useful pattern in Mount Pleasant is one visit once the drop has genuinely finished, in late December or January, and a second in spring, which here is not a leaf job at all. Spring is pine pollen, catkins and seed, and it washes into the outlets and sets there. A spring visit is a downspout job with a gutter attached.
Whatever the schedule, the visit finishes the same way anywhere we work: hand-cleared into a bucket rather than blown off the roof, every downspout flow-tested with a hose, and photographs from the ladder of every run before and after. You are hiring us precisely because you are not going up there, so you get the evidence rather than the assurance.

What Mount Pleasant itself changes
Getting to the gutters
The historic core has the constraints its period implies: narrow lots, buildings close to the street, tall elevations relative to footprint, and porches and bay features that put a run above a roof rather than above open ground. None of it is unmanageable and all of it is slower than open subdivision work. The newer edges are ordinary.
The housing in Mount Pleasant
Mount Pleasant has a listed historic district at its centre and newer building around the edges, and the distinction is unusually visible from the street. The older buildings were designed with deep overhangs, moulded fascia and decorative eaves detailing, and that detailing is exactly what a gutter has to be fitted to. On a house of that period the profile is an appearance decision as much as a drainage one, and a stock K-style run fastened across carved eaves reads as wrong even to somebody who could not say why.
