Reidsville Homes and Their Attics

Story-and-a-Half Cottages Built for the Factory

When American Tobacco expanded in the 1910s, prominent local citizens had small frame houses built to rent to the plant's Black workers. Many went up between 1915 and 1930, in clusters across the northern third of the city. The city's 1986 multiple resource nomination describes the usual plan: one room wide, two rooms deep, a story and a half high, with a shed roof over the back room. For the North Washington Avenue group, it describes an upstairs room whose knee walls slope up to a narrow flat ceiling. That shape leaves only a sliver of attic overhead. The wedge-shaped spaces behind those knee walls are often leaky, and the floor cavities under the walls can stand open. We seal and insulate the side wedges and those openings, not only the strip above.

Courtland Place and the Postwar Subdivisions

Courtland Place, the city's first planned subdivision, opened in southwest Reidsville in the early 1920s with curving streets and park land. The 1986 nomination notes that bungalows and revival style houses went up there in the 1920s and 1930s, but that most of its building came in the late 1940s and 1950s. Later middle class streets followed near the Pennrose Country Club and along Richardson Drive. The housing figures on this page date about half of Reidsville's homes to before 1970. A kitchen from those years may have a boxed soffit above the wall cabinets with its top open straight into the attic. ENERGY STAR counts these dropped soffits among the big leaks: we rake the insulation aside, cap and seal the opening from above, and lay the insulation back across the top.

Attic Insulation in Reidsville

About 55 percent of Reidsville's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.

Built from 1940 to 1969, about 45 percent of Reidsville homes often have little insulation.

The Local Climate

Reidsville's center sits about 800 feet above sea level, 2 miles from NOAA's Reidsville 2 NW station, the best match for Reidsville. The station's 1991 to 2020 normals average about 3,830 heating and 1,340 cooling degree days a year, so at Reidsville's station, heating needs outweigh cooling.

Homes by Age: What It Means for the Attic

Some 70 percent of Reidsville housing units are detached single-family houses.

Built from 1970 to 1989, 21 percent of Reidsville homes may hold settled fiberglass; check its depth against the joists.

About 70 percent of Reidsville's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 26 percent of Reidsville units sit in buildings of two or more homes, where the attic is often shared.

Reidsville Insulation FAQs

Does the Reidsville Historic District limit work on my attic?

Not through its National Register listing. Listed in 1987, the district takes in about 140 acres: downtown, an industrial area and residential streets to the west and southeast. Register status, the State Historic Preservation Office explains, does not tie the hands of a private owner spending private money. The city also has its own Historic Preservation Commission. If your house sits in a local district or is a landmark it has designated, outside changes need its certificate of appropriateness, while interior arrangement is beyond its reach. Air sealing and insulation are inside work, but check with the city before cutting new roof vents.

Our little house in north Reidsville has a chimney between the two rooms. Does that matter?

Yes, it is one of the first places we look. The 1986 nomination for the North Washington Avenue Workers' Houses describes a brick chimney rising between the front and back rooms, which carries it straight up through the ceiling. ENERGY STAR calls the opening around a chimney a major path for warm air into the attic. It is closed with aluminum flashing pressed into high-temperature caulk, and a metal barrier keeps the insulation off the masonry, with about 2 inches of clearance.

Could the old insulation in a Reidsville attic be vermiculite?

It could: about 37 percent of Reidsville's homes predate 1960. If a Reidsville 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 Reidsville need a permit?

Reidsville City Hall can say whether Rockingham County, the city itself or another office handles permits in Reidsville; ask before work starts.
