Randolph County, WV Insulation Payback
Randolph County, WV: what topping up your attic actually costs
Randolph County, West Virginia is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. An uninsulated attic there should be built up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.2 years at an estimated $1,554/year saved. That's about as fast as attic paybacks get.
Heating vs. cooling in Randolph County
The estimated savings split roughly $1,455/year heating, $99/year cooling. Out of every 100 US counties tracked here, Randolph County's savings potential beats roughly 57 of them. Within zone 5 specifically, it ranks 690th of 745 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Randolph County comes in 2% higher.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,442 HDD and 617 CDD (base 65°F, 1991-2020 normals) — come from ELKINS RANDOLPH CO AP, WV US, the nearest NOAA station with published normals, 7.2 miles from Randolph County's center. That combined heating-and-cooling load ranks Randolph County 1489th nationally by total degree days — the 53th percentile. Randolph County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $227/year saved — roughly 10.1 years to break even. This one is a genuine toss-up, not a clear yes.
