Webster County, WV Insulation Payback
Webster County, WV: what topping up your attic actually costs
Webster County sits in IECC climate zone 5 (Cold) — a real winter that drives most of the annual energy bill 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 $1,557 a year — payback in roughly 2.2 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,470/year heating, $88/year cooling. Out of every 100 US counties tracked here, Webster County's savings potential beats roughly 57 of them. Within zone 5 specifically, it ranks 687th of 745 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Webster County comes in 2% higher.
Webster County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 5,496 HDD and 547 CDD (base 65°F, 1991-2020 normals) — come from WEBSTER SPRINGS 8 N, WV US, the nearest NOAA station with published normals, 4 miles from Webster County's center. Combined heating and cooling load puts Webster County in the 53th percentile of this 3,162-county dataset. Webster 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
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 $227/year saved (~10-year payback). This one is a genuine toss-up, not a clear yes.
