Cuyahoga County, OH Insulation Payback
Attic insulation payback for Cuyahoga County, OH
Cuyahoga County, Ohio is zone 5 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. An uninsulated attic there should be built up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,623 a year in heating and cooling — a payback around 2.1 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Cuyahoga County
Of that, about $1,474/year comes from reduced heating and $149/year from reduced cooling load through the ceiling. Cuyahoga County beats 61% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Cuyahoga County ranks 611th. Against Ohio's own average of $1,669/year, Cuyahoga County runs 3% below that.
Cuyahoga County's actual weather, not a national average
NOAA's CLEVELAND BURKE AP, OH US station, 4.8 miles from Cuyahoga County, supplies the 5,513 HDD and 925 CDD this estimate runs on. By total degree days, Cuyahoga County sits at the 61th percentile nationally. DOE also classifies Cuyahoga County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
If Cuyahoga County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $237/year — payback about 9.6 years. It is close - the payback only just fits a reasonable timeframe.
