Nobody chooses a pool because of the cover. Around here, though, a cover does more work per dollar than almost anything else on the quote, because it sits between your water and the thing that shortens your season.
Why covers matter more at this elevation
Clear nights around Asheville draw heat out of a pool overnight, and most of that heat leaves through the surface of the water. A cover puts a lid on the single biggest loss a mountain pool has.
Leaves are the second reason to fit one. A great deal of property around Asheville has hardwoods around it, and an uncovered pool in October becomes a full time job with a net, whereas a covered one is a job you do at the start and end of the season.
Safety is the third, and it is the one that changes what you worry about. A properly specified safety cover carries weight, which is a different level of protection from a barrier alone, and it matters on any property where children or dogs move around the yard unsupervised. Nobody plans for the afternoon when a gate gets left open, which is exactly why a cover that holds weight is worth having on a property with a slope running down toward the water.
