Attic Insulation in Arapahoe
If the joists show above the insulation in an Arapahoe attic, ENERGY STAR says to add more insulation.
The Local Climate
Arapahoe's center sits about 40 feet above sea level, 7 miles from NOAA's Bayboro 3 SW station, the best match for Arapahoe. The station's 1991 to 2020 normals average about 2,820 heating and 1,700 cooling degree days a year, so at Arapahoe's station, heating needs outweigh cooling.
Readings change over short distances around Arapahoe: NOAA's Reelsboro station, 9 miles away, averages about 2,490 heating degree days.

Arapahoe Insulation FAQs
Arapahoe sits outside the flood zone. Can a hurricane still soak my attic?
Yes, from above. The 2020 regional hazard mitigation plan puts no part of the town inside the 100-year flood zone. So the storm water to worry about in an attic here is rain driven through the roof. When Hurricane Isabel crossed eastern North Carolina in 2003, the Weather Service counted Pamlico among the counties with the heaviest rain. Damp insulation after a storm means a roof leak. Roof repairs come first, and then we vacuum out the wet material and replace it.
Does any historic designation limit work on houses in this Pamlico County town?
No. In the National Register rows the state keeps for Pamlico County, nothing is in Arapahoe, and the 2023 commission roster shows none at work in Pamlico. Nobody reviews attic insulation here for historic reasons.
Does attic insulation in Arapahoe need a permit?
Arapahoe Town Hall can say whether Pamlico County Inspections Department, the town itself or another office handles permits in Arapahoe; ask before work starts.
