Why the reversal cost matters more in Stallings
Uniform and easy. The town is essentially one large cohort of subdivision housing with the layout that implies: level drives, standard setbacks, two-storey elevations of predictable height. There is very little in Stallings that needs anything other than a ladder and a normal working position, which keeps quotes here at the lower end of the access range.
That is worth reading before deciding between the two products people call leaf guard, because the harder a roof is to reach, the more expensive it is to change your mind about what is on it.
A cover that clips over your existing gutter is reversible: removal is $1.50 to $3 a foot and the gutter underneath is untouched. A one-piece system, where the hood and the gutter are a single extruded unit, is not. Taking the hood off means taking the gutter off, because they are the same object, so undoing it is a full replacement, $2 to $4 a foot to remove, then $8 to $17 a foot for a new run. On a 150-foot house that is roughly $1,500 to $3,150 to get back to a conventional gutter, before the access surcharge that Stallings height adds to both halves.
That asymmetry is essentially never mentioned at the point of sale, and it is the single most important fact about this category. So: ask any company quoting a one-piece system what removal would cost, and note whether the answer comes readily.
On the product itself, reverse-curve uses surface tension to carry water around a curved lip into a narrow slot. It works, up to a flow rate. Charlotte peaks at 7.27 inches of rain an hour over a five-minute burst, and past the point where surface tension holds, water leaves the nose in a straight line and goes over the slot entirely. Under willow oak and pine we recommend stainless micro-mesh at $10 to $18 a foot instead: finer aperture, roughly half the price, and it unclips.

What Stallings itself changes
What drops on these roofs
Light to moderate, and similar in character to neighbouring Indian Trail, farmland converted to subdivision, with planted trees that are only now reaching the height of the eaves on the earliest streets. The debris load is genuinely low by metro standards. What Stallings does get, like the whole of the Union County side, is the spring pine pollen and catkin drop, which washes into the outlets and sets there, so the spring visit here is a downspout job with a gutter attached.
The housing in Stallings
At 62.6% built between 1990 and 2009, Stallings has the most concentrated housing cohort of any town in this study, and with a median of 2002 that cohort has now arrived at a very specific age. Aluminium at twenty-four years is nowhere near finished. The sealant in its mitres and end caps is a different matter: it is a compound with a service life measured in one to two decades, not the same as the metal it sits in, and across Stallings it is reaching the end of that life more or less simultaneously. Almost every gutter call we take from this town is a corner that has started weeping.
