Webster County, WV: what topping up your attic actually costs

Fast payback
2.2yr payback

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.

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 695th of 754 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 52nd percentile of this 3,171-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.

Get quotes from at least two local contractors before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth checking upfront given Webster County's estimated $1,557/year on the line.

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.
