Ritchie County, WV Insulation Payback
Ritchie County, WV: what topping up your attic actually costs
DOE classifies Ritchie County as climate zone 4, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. Its recommended attic R-value for bare joists is 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 $1,536 a year — payback in roughly 2.3 years. That's about as fast as attic paybacks get.
Heating vs. cooling in Ritchie County
The estimated savings split roughly $1,400/year heating, $136/year cooling. Out of every 100 US counties tracked here, Ritchie County's savings potential beats roughly 55 of them. Within zone 4 specifically, it ranks 125th of 825 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Ritchie County comes in 1% higher.
Where these numbers come from
NOAA's HARRISVILLE, WV US station, 3 miles from Ritchie County, supplies the 5,236 HDD and 845 CDD this estimate runs on. That combined heating-and-cooling load ranks Ritchie County 1475th nationally by total degree days — the 53th percentile. Ritchie County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
If Ritchie 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 $224/year — payback about 10.2 years. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
