About Columbia and Its Homes
Columbia, the Tyrrell County seat, began as a trading post called Shallop's Landing on the Scuppernong River and was incorporated in 1793 as Elizabeth Town. Its historic core sits on flat, low ground by the estuary and was built up mostly in frame after a late-1800s lumber boom.
Columbia, in Tyrrell County, grew from 612 people in 2020 to 613 in 2025 (Census Bureau estimates), on 1.23 square miles.

Columbia Homes and Their Attics
Story-and-a-Half Houses Along the Old Streets
The Columbia Historic District's 1994 inventory lists around twenty story-and-a-half houses. They run from an 1880s cottage with paired steep front gables to 1920s and 1930s Craftsman bungalows with dormers front and back, several of them built as rentals. The nomination adds that many of the town's houses of that era appear to have been used as speculative rentals. A house of that shape seldom has one simple attic. There is a strip of attic behind each low upstairs wall, a small cavity over each dormer and sometimes another over a one-story ell. By ENERGY STAR's account, the open framing beneath those low walls leaks even with insulation stuffed in, so the strips get sealed as well as filled.

The Local Climate
Columbia's center sits near sea level, 16 miles from NOAA's Columbia Ag Gum Neck station, the best match for Columbia. The station's 1991 to 2020 normals average about 3,120 heating and 1,620 cooling degree days a year, so at Columbia's station, heating needs outweigh cooling. Readings change over short distances around Columbia: NOAA's Edenton station, 18 miles away, averages about 2,870 heating degree days.
Homes by Age: What It Means for the Attic

Columbia Insulation FAQs
Does the Columbia Historic District have rules about insulating my attic?
No. Columbia's district, added to the National Register in 1994, takes in most of the old town core. Still, Register status by itself sets no conditions on a homeowner paying for work with their own money, according to the state preservation office. Tyrrell County is missing entirely from the 2023 state listing of local preservation commissions, so no local body reviews changes here. And attic insulation and ceiling sealing happen indoors either way.
What should a Columbia homeowner check in the attic after a hurricane?
Start with the roof boards, then the insulation lying under them. Storms here bring both wind and rain. During Hurricane Irene in 2011, the National Weather Service reported an EF-2 tornado near Columbia that demolished at least 4 homes. During Hurricane Dorian in 2019, it logged 8.75 inches of rain at Columbia Town Hall. Clumped or damp insulation means the roof leaks. ENERGY STAR lists that among the problems to correct before insulating. Once the roof is tight, we pull out the wet fill by vacuum and blow in a fresh layer.
Does attic insulation in Columbia need a permit?
Columbia Town Hall can say whether Tyrrell County, the town itself or another office handles permits in Columbia; ask before work starts.
