About Rose Hill and Its Homes
Rose Hill was settled in the late 1840s beside the Wilmington and Weldon tracks as a shipping point for turpentine and tar, and was chartered in 1875. Lumber and a casket factory followed, and most of its business district dates from the middle of the twentieth century.
Rose Hill, in Duplin County, grew from 1,366 people in 2020 to 1,429 in 2025 (Census Bureau estimates), on 1.45 square miles. That makes Rose Hill the third-largest town in Duplin County.
Rose Hill has about 620 housing units, 3 percent of Duplin County's; about 57 percent of the town's households own their home.

Rose Hill Homes and Their Attics
Postwar Ranches and Their Shallow Edges
After World War II, Duplin County's survey found, new houses were mostly small 1940s and 1950s cottages, minimal traditional houses and ranches. About half of the homes in Rose Hill predate 1970, by Census estimates. A postwar study of ranch houses describes the basic form as a long rectangle under a gently pitched roof. That leaves very little room between the ceiling and the roof boards out near the walls. ENERGY STAR points out that this outer strip can be where the old layer runs thinnest. Before blowing insulation, we staple a rafter vent to the roof boards above every soffit vent so air keeps moving, then fill right out over the wall plates.
Attic Insulation in Rose Hill
If the joists show above the insulation in a Rose Hill attic, ENERGY STAR says to add more insulation.
The Local Climate
Rose Hill's center sits about 100 feet above sea level, 7 miles from NOAA's Wallace 1 SE station, the best match for Rose Hill. The station's 1991 to 2020 normals average about 2,900 heating and 1,850 cooling degree days a year, so at Rose Hill's station, heating needs outweigh cooling.
Readings change over short distances around Rose Hill: NOAA's Warsaw 5 E station, 13 miles away, averages about 3,490 heating degree days.
Homes by Age: What It Means for the Attic
About 78 percent of Rose Hill housing units are detached single-family houses.
Built from 1970 to 1989, about 20 percent of Rose Hill homes may hold settled fiberglass; check its depth against the joists. From 1990 to 2009, about 15 percent of Rose Hill homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.

Rose Hill Insulation FAQs
Is anything in Rose Hill on the National Register of Historic Places?
No. Not one Rose Hill property appears on the state's National Register roll, though Duplin County's survey in the 1990s did record the town's commercial area and its early brick store building. The only local preservation commission the state lists for the county belongs to Warsaw. So no historic designation shapes what you do in your Rose Hill attic.
Would a radiant barrier make my Rose Hill house cooler in summer?
It depends on what is already in the attic. Rose Hill sits in the southern Coastal Plain, and on a long July afternoon the roof deck over a ranch can get very hot. Building America finds a radiant barrier cuts a large share of attic heat when there is little insulation below it, and adds little over a ceiling that is already well insulated. It also keeps ducts that run through the attic cooler. Insulation and air sealing come first, and that is the work we do.
Could the old insulation in a Rose Hill attic be vermiculite?
It could: about 30 percent of Rose Hill's homes predate 1960. If a Rose Hill attic holds a pebble-like gray-brown or silver-gold fill, leave it undisturbed: the EPA says vermiculite may contain asbestos.
Does attic insulation in Rose Hill need a permit?
Rose Hill Town Hall can say whether Duplin County Building Inspections, the town itself or another office handles permits in Rose Hill; ask before work starts.
