Ohio County, WV Insulation Payback
Is attic insulation worth it in Ohio County, WV?
Ohio County sits in IECC climate zone 5 (Cold) — cold enough that heating, not cooling, is what decides the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,586 a year in heating and cooling — a payback around 2.2 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Ohio County
Heating accounts for about $1,449/year of that and cooling about $137/year — Ohio County needs both. Nationally, Ohio County ranks in the 59th percentile for insulation savings potential. Compared only against its own climate zone, Ohio County places 654th out of 745. Against West Virginia's own average of $1,526/year, Ohio County runs 4% above that.
The climate data behind this
NOAA's PIKE ISLAND(LOCK & DAM), WV US station, 5.4 miles from Ohio County, supplies the 5,420 HDD and 853 CDD this estimate runs on. By total degree days, Ohio County sits at the 57th percentile nationally. 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
If Ohio County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $231/year — payback about 9.9 years. Whether that is worth it depends on how long you plan to stay.
