Rooks County, KS Insulation Payback
Is attic insulation worth it in Rooks County, KS?
Rooks County, Kansas is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. 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 $1,652 a year — payback in roughly 2.1 years.
Few home upgrades pay back that quickly.
Heating vs. cooling in Rooks County
Heating accounts for about $1,435/year of that and cooling about $217/year — Rooks County needs both. Nationally, Rooks County ranks in the 63rd percentile for insulation savings potential. Compared only against its own climate zone, Rooks County places 573rd out of 754. Against Kansas's own average of $1,594/year, Rooks County runs 4% above that.
The climate data behind this
NOAA's Webster DAM, KS US station, 6.4 miles from Rooks County, supplies the 5,367 HDD and 1,352 CDD this estimate runs on. Combined heating and cooling load puts Rooks County in the 66th percentile of this 3,171-county dataset. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
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 $241/year saved — roughly 9.5 years to break even. Whether that is worth it depends on how long you plan to stay.
