Leflore County, MS Insulation Payback

Leflore County, MS: what topping up your attic actually costs

DOE classifies Leflore County as climate zone 3, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,040 a year — payback in roughly 2.7 years. That's about as fast as attic paybacks get.

Heating vs. cooling in Leflore County

The estimated savings split roughly $683/year heating, $357/year cooling. Out of every 100 US counties tracked here, Leflore County's savings potential beats roughly 20 of them. Within zone 3 specifically, it ranks 385th of 690 counties by estimated savings. Mississippi averages $1,022/year across the counties tracked here; Leflore County comes in 2% higher.

The climate data behind this

Leflore County's climate figures — 2,573 heating and 2,243 cooling degree days a year — are read from GREENWOOD LEFLORE AP, MS US, 12.5 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Leflore County sits at the 20th percentile nationally. Leflore 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

Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $140/year saved — roughly 11.6 years to break even. This one is a genuine toss-up, not a clear yes.

Next steps for a Leflore County attic

Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Leflore County job, not a quote. Expect at least a $600 minimum charge from most contractors.

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-49 is the target here specifically.
