Why the reversal cost matters more in Matthews
Comfortable. Mostly two-storey and split-level housing on regular suburban lots with proper driveways, level ground and reasonable setbacks. The older centre around the town green has tighter lots and some genuinely period buildings, but the great majority of Matthews work is ordinary ladder access with the standard two-storey surcharge on the upper runs.
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 Matthews 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 Matthews itself changes
What drops on these roofs
This is the defining fact about gutters in Matthews and it follows directly from the housing age. Trees planted with a house in 1985 are now forty years old, which means they have gone from ornamental to structural in scale and their canopies have closed over the roofs rather than sitting beside them. Matthews neighbourhoods that needed one clean a year in 2005 now need two, and homeowners here often describe the change as something that happened to the gutters when what changed was the trees.
The housing in Matthews
Matthews is older than its reputation suggests. Its single biggest decade is the 1980s at 23.1%, and 45.3% of the housing went up between 1980 and 1999, which puts the bulk of the town at thirty to forty-five years old rather than in the modern-subdivision bracket people assume. For gutters that age is the interesting one: it straddles the change from spike-and-ferrule to hidden hangers, so two Matthews houses on the same street built six years apart can have completely different fastening systems and completely different prognoses.
