Hoonah-Angoon Census Area, AK Insulation Payback
Hoonah-Angoon Census Area, AK: what topping up your attic actually costs
Hoonah-Angoon Census Area, Alaska is zone 7 under DOE's climate map (Very Cold), which means winters long and harsh enough that heating is essentially the entire equation. 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 $2,350 a year — payback in roughly 1.5 years. That's about as fast as attic paybacks get.
Where the savings come from
Cooling barely factors in here; essentially the full $2,350/year is heating savings. Out of every 100 US counties tracked here, Hoonah-Angoon Census Area's savings potential beats roughly 94 of them. Within zone 7 specifically, it ranks 104th of 120 counties by estimated savings. Alaska averages $2,854/year across the counties tracked here; Hoonah-Angoon Census Area comes in 18% lower.
Hoonah-Angoon Census Area's actual weather, not a national average
Hoonah-Angoon Census Area's climate figures — 8,788 heating and 0 cooling degree days a year — are read from GLACIER BAY, AK US, 3.7 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Hoonah-Angoon Census Area sits at the 93th percentile nationally.
The smaller top-up scenario
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 $343/year saved (~6.7-year payback). That is a solid payback as home upgrades go.
Next steps for a Hoonah-Angoon Census Area attic
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 Hoonah-Angoon Census Area, 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.
