Ramsey County, ND Insulation Payback
Ramsey County, ND: what topping up your attic actually costs
DOE classifies Ramsey County as climate zone 7, very cold — severe, long winters where heating is nearly the whole story. 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 $2,589 a year — payback in roughly 1.3 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $2,521/year heating, $68/year cooling. Out of every 100 US counties tracked here, Ramsey County's savings potential beats roughly 98 of them. Within zone 7 specifically, it ranks 46th of 120 counties by estimated savings. North Dakota averages $2,496/year across the counties tracked here; Ramsey County comes in 4% higher.
The climate data behind this
NOAA's DEVILS LAKE KDLR, ND US station, 12.5 miles from Ramsey County, supplies the 9,428 HDD and 424 CDD this estimate runs on. By total degree days, Ramsey County sits at the 98th percentile nationally.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $378/year saved — roughly 6 years to break even. That is a solid payback as home upgrades go.
Next steps for a Ramsey County attic
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Ramsey 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-60 is the target here specifically.
