Noble County, OH Insulation Payback
Noble County, OH: what topping up your attic actually costs
Noble County, Ohio is zone 5 under DOE's climate map (Cold), which means a real winter that drives most of the annual energy bill here. An uninsulated attic there should be built 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 $1,583 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 $1,478/year heating, $106/year cooling. Out of every 100 US counties tracked here, Noble County's savings potential beats roughly 58 of them. Within zone 5 specifically, it ranks 659th of 745 counties by estimated savings. Ohio averages $1,669/year across the counties tracked here; Noble County comes in 5% lower.
Where these numbers come from
NOAA's CALDWELL 3SE, OH US station, 3.6 miles from Noble County, supplies the 5,527 HDD and 657 CDD this estimate runs on. By total degree days, Noble County sits at the 56th percentile nationally. Noble County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
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 $231/year saved (~9.9-year payback). This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
