Raleigh County, WV Insulation Payback
Raleigh County, WV: what topping up your attic actually costs
DOE classifies Raleigh County as climate zone 5, cold — a real winter that drives most of the annual energy bill 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 $1,635 a year — payback in roughly 2.1 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,579/year heating, $56/year cooling. Out of every 100 US counties tracked here, Raleigh County's savings potential beats roughly 62 of them. Within zone 5 specifically, it ranks 598th of 745 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Raleigh County comes in 7% higher.
Raleigh County's actual weather, not a national average
NOAA's BECKLEY VA HOSPITAL, WV US station, 3.9 miles from Raleigh County, supplies the 5,904 HDD and 351 CDD this estimate runs on. By total degree days, Raleigh County sits at the 57th percentile nationally. Raleigh County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
The smaller top-up scenario
If Raleigh 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 $238/year — payback about 9.6 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.
