Leslie County, KY Insulation Payback
Is attic insulation worth it in Leslie County, KY?
Leslie County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,325 a year — payback in roughly 2.6 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Leslie County
Heating accounts for about $1,156/year of that and cooling about $169/year — Leslie County needs both. Nationally, Leslie County ranks in the 40th percentile for insulation savings potential. Compared only against its own climate zone, Leslie County places 534th out of 825. Against Kentucky's own average of $1,385/year, Leslie County runs 4% below that.
Leslie County's actual weather, not a national average
NOAA's BAXTER, KY US station, 16.2 miles from Leslie County, supplies the 4,324 HDD and 1,051 CDD this estimate runs on. That combined heating-and-cooling load ranks Leslie County 2003rd nationally by total degree days — the 37th percentile. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $193/year saved (~11.8-year payback). Whether that is worth it depends on how long you plan to stay.
