About Beaufort and Its Homes
Beaufort, the Carteret County seat opposite Beaufort Inlet, was laid out about 1713 and first called Fishtown. Its 1974 nomination describes an old street grid of one- and two-story frame houses whose gable roofs typically break into several slopes over porches and back rooms.
Beaufort, in Carteret County, grew from 4,475 people in 2020 to 4,912 in 2025 (Census Bureau estimates), on 5.09 square miles. That makes Beaufort the second-largest town in Carteret County.
Beaufort has about 3,400 housing units, 6 percent of Carteret County's; about 53 percent of the town's households own their home. About 2,600 of those 3,400 units were someone's usual home in the Census Bureau's 2020 to 2024 survey; the heating and owner figures on this page describe those 2,600.

Beaufort Homes and Their Attics
Roofs That Break Into Three or More Slopes
The 1974 National Register nomination for the Beaufort Historic District picks out the town's typical roof. It rises steeply near the ridge, then breaks to a shallower pitch over a front porch and over a porch or enclosed room at the back. Most have at least three slopes, many have four, and one house that took on additions has five. Where the low rear slope covers a room rather than a porch, the attic above that room is a shallow wedge, easy to miss from the main hatch. Attics can run short of insulation at their edges, ENERGY STAR notes, so those low corners get an even layer too.
Old Windows Built to Air Out the Attic
The same nomination records an old local way of airing out attics. One early coastal cottage on Ann Street has small four-pane windows at attic floor level behind a porch with no ceiling. Two other houses have trap doors in the porch ceiling that open to let air through attic windows, and the writers thought the scheme was once more common. The idea holds up: an attic needs air moving through it, drawn in under the eaves and let out near the ridge or gables. ENERGY STAR warns never to bury soffit vents in insulation, and baffles hold a clear path open when more is added.
Attic Insulation in Beaufort
About 35 percent of Beaufort's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
From 1990 to 2009, about 30 percent of Beaufort homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Beaufort's center sits near sea level, 1 mile from NOAA's Beaufort Michael J. Smith Field station, the best match for Beaufort. The station's 1991 to 2020 normals average about 2,380 heating and 1,980 cooling degree days a year, so Beaufort attics work in both seasons.
The state energy code marks Carteret County warm and humid.
Homes by Age: What It Means for the Attic
About 63 percent of Beaufort housing units are detached single-family houses.
Built from 1940 to 1969, 22 percent of Beaufort homes often have little insulation.
About 45 percent of Beaufort's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 32 percent of Beaufort units sit in buildings of two or more homes, where the attic is often shared.
Homes by Year Built
- Before 1940: 15% (±4), about 510 units
- 1940s: 9% (±4), about 310 units
- 1950s: 5% (±3), about 170 units
- 1960s: 8% (±4), about 260 units
- 1970s: 7% (±3), about 225 units

- 2020 or later: 2% (±2), about 80 units
Air Sealing and Duct Sealing in Beaufort
In Beaufort, 92 percent of homes heat with electricity; where that heat is forced air, ducts often run through the attic.
Air sealing comes first, as the EPA advises: wire and pipe holes, wall tops and soffits.
How Homes Here Are Heated
- Electricity: 92% (±4), about 2,400 households; Carteret County: 87%
- Piped gas: under 2%, about 30 households
- Bottled or tank gas: 5% (±2), about 130 households

Attic Insulation Removal in Beaufort
In a Beaufort attic, only wet, moldy or animal-soiled insulation is vacuumed out (ENERGY STAR's test), once the cause is fixed, and after mice that Beaufort attic is sanitized and deodorized; dry, clean insulation stays.

Beaufort Insulation FAQs
Will the Beaufort preservation commission need to approve insulation work in my attic?
Not for the work itself. Beaufort does have its own Historic Preservation Commission. Under state law, a commission like it rules on exterior changes in a local district or landmark, while the interior arrangement stays outside its reach. Blowing insulation and sealing leaks in an attic happen indoors. Vents cut through a roof or gable alter the outside, though, and in a local district those need the commission's sign-off first, so raise them with the town early. The 1974 National Register listing adds no limits of its own on a private owner.
Does the old chimney in my Beaufort house pass through the attic?
That depends on where it stands. The 2012 county survey describes the traditional Carteret house as a gable-roofed box with a chimney at one end. Beaufort's nomination adds a local style of chimney, built out in brick behind the first-floor fireplace. If yours stands outside the gable wall, it never enters the attic. If a chimney or a later stove flue rises through a ceiling, ENERGY STAR calls for closing the open ring around it with light aluminum sheet held by heat-rated caulk. A metal dam around it keeps insulation off the brick or pipe.
Could the old insulation in a Beaufort attic be vermiculite?
It could: about 30 percent of Beaufort's homes predate 1960. If a Beaufort 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 Beaufort need a permit?
Beaufort Town Hall can say whether Carteret County Planning & Development, the town itself or another office handles permits in Beaufort; ask before work starts.
