About Winfall and Its Homes
Winfall, across the Perquimans River from Hertford, was laid out on a street grid in 1873 and grew after the Norfolk and Southern Railroad reached it in 1881. Its historic district is mostly one- and two-story frame houses from 1880 to 1930, many with rear ells and interior chimneys.
Winfall, in Perquimans County, grew from 551 people in 2020 to 575 in 2025 (Census Bureau estimates), on 2.31 square miles.
Winfall has about 370 housing units, 5 percent of Perquimans County's.

Winfall Homes and Their Attics
Coastal Cottages With Shed Rooms at the Back
The district's nomination names the coastal cottage as one of the traditional house forms that Perquimans County builders kept using into the early 1900s. Winfall's example, from about 1871, is a story-and-a-half frame house with an engaged front porch and shed rooms across the rear. A house like this has its attic in parts. If the upstairs is finished, its rooms sit behind short knee walls, with narrow wedges of attic beside them, and the rear shed rooms sit under a shallower roof of their own. Each part is reached and filled evenly, and the knee walls and the open floor behind them are sealed, since air leaks there.
Attic Insulation in Winfall
About 25 percent of Winfall's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
The Local Climate
Winfall's center sits near sea level, 15 miles from NOAA's Edenton station, the best match for Winfall. The station's 1991 to 2020 normals average about 2,870 heating and 1,840 cooling degree days a year, so at Winfall's station, heating needs outweigh cooling.
Homes by Age: What It Means for the Attic
With about 370 housing units in Winfall, read the figures as rough proportions.
Built from 1940 to 1969, about 15 percent of Winfall homes often have little insulation. Built from 1970 to 1989, about 25 percent of Winfall homes may hold settled fiberglass; check its depth against the joists.
About 33 percent of Winfall's housing units predate 1980; nearly all predate the state's 1978 insulation rule too.

Winfall Insulation FAQs
Do I need approval to work on a house inside the Winfall Historic District?
No approval comes with the listing. Main Street and its side streets joined the National Register in 2003, and the state preservation office treats that as recognition. An owner spending private funds on the house is free to maintain or change it. When the office listed local preservation commissions in 2023, Perquimans County had none. Sealing and insulating the attic happens indoors anyway. Only new vents cut through the roof would change the outside, so ask the town about those.
Can the landlord of a Winfall rental house have the attic insulated?
Yes, that call belongs to whoever owns the house, and a tenant who is cold in winter can ask for it. Rentals go back a long way in Winfall. The nomination says many district houses were rented from the day they were finished, and two local builders put up one-story houses to sell or let. Settle a day with the tenant, since the way into the attic is often indoors. We seal the ceiling gaps from above, then blow in the insulation.
Could the old insulation in a Winfall attic be vermiculite?
It could: about 20 percent of Winfall's homes predate 1960. If a Winfall 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 Winfall need a permit?
Winfall Town Hall can say whether Perquimans County Building Inspector, the town itself or another office handles permits in Winfall; ask before work starts.
