Erie County, NY Insulation Payback
Attic insulation payback for Erie County, NY
DOE classifies Erie County as climate zone 5, cold — a real winter that drives most of the annual energy bill 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 $2,000 a year — payback in roughly 1.7 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Erie County
Of that, about $1,948/year comes from reduced heating and $52/year from reduced cooling load through the ceiling. Erie County beats 82% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Erie County ranks 44th. Against New York's own average of $1,948/year, Erie County runs 3% above that.
Where these numbers come from
NOAA's COLDEN 1 N, NY US station, 7.9 miles from Erie County, supplies the 7,285 HDD and 322 CDD this estimate runs on. By total degree days, Erie County sits at the 81th percentile nationally. DOE also classifies Erie 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
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $292/year saved — roughly 7.8 years to break even. Topping up the attic pays for itself here.
