Monroe County, WV Insulation Payback
Monroe County, WV: what topping up your attic actually costs
DOE classifies Monroe 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 $1,490 a year — payback in roughly 2.3 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,374/year heating, $116/year cooling. Out of every 100 US counties tracked here, Monroe County's savings potential beats roughly 52 of them. Within zone 4 specifically, it ranks 190th of 825 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Monroe County comes in 2% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,137 HDD and 725 CDD (base 65°F, 1991-2020 normals) — come from UNION 3 SSE, WV US, the nearest NOAA station with published normals, 1.2 miles from Monroe County's center. Combined heating and cooling load puts Monroe County in the 49th percentile of this 3,162-county dataset. Monroe 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 $217/year saved — roughly 10.5 years to break even. This one is a genuine toss-up, not a clear yes.
Next steps for a Monroe County attic
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Monroe County job, not a quote. Expect at least a $600 minimum charge from most contractors.
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.
