Attic Insulation in Red Oak
About 20 percent of Red Oak's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
From 1990 to 2009, about 35 percent of Red Oak homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Red Oak's center sits about 200 feet above sea level, 13 miles from NOAA's Rocky Mount-Wilson Airport station, the best match for Red Oak. The station's 1991 to 2020 normals average about 3,270 heating and 1,680 cooling degree days a year, so at Red Oak's station, heating needs outweigh cooling.

Red Oak Insulation FAQs
Is any house in Red Oak on the National Register?
Not a house, as far as the state's lists show. The one Register property the state places in town is its community house, a log hall that local men raised in 1935. The town owned it when it was listed in 2006. Black Jack, the other listing nearby, stands outside the town limits. The state's 2023 list names no preservation commission here, so no historic rules shape attic work.
Why does the room over the garage in our newer Red Oak house run hot and cold?
Because it sits over space that is not heated, with attic on its sides and above. Building America's guidance for a floor over a garage is to air seal it and keep the insulation tight against the subfloor, not sagging below it. ENERGY STAR also lists the gaps behind and under knee walls among common attic leaks, and a room over a garage may have short side walls. So we seal the floor edges and the knee walls first, then insulate the floor, the side walls and the ceiling above. We can insulate the garage itself too.
Does attic insulation in Red Oak need a permit?
Red Oak Town Hall can say whether Nash County Building Inspections, the town itself or another office handles permits in Red Oak; ask before work starts.
