Menominee County, MI Insulation Payback
Menominee County, MI: what topping up your attic actually costs
Menominee County sits in IECC climate zone 6 (Cold) — cold enough that heating, not cooling, is what decides the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $2,276 a year in heating and cooling — a payback around 1.5 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $2,225/year heating, $52/year cooling. Out of every 100 US counties tracked here, Menominee County's savings potential beats roughly 93 of them. Within zone 6 specifically, it ranks 115th of 459 counties by estimated savings. Michigan averages $2,064/year across the counties tracked here; Menominee County comes in 10% higher.
Menominee County's actual weather, not a national average
NOAA's STEPHENSON 5WSW, MI US station, 14 miles from Menominee County, supplies the 8,320 HDD and 321 CDD this estimate runs on. By total degree days, Menominee County sits at the 92th percentile nationally. Menominee 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?
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 $332/year saved (~6.9-year payback). That is a solid payback as home upgrades go.
Quotes and materials for this job
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Menominee County, not a bid - contractors typically charge a $600 minimum regardless of job size.
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.
