About Valdese and Its Homes
Valdese was settled in 1893 by Waldensian families from northern Italy and incorporated in 1920, the only North Carolina town the Waldensians founded. Stone was the building material of their home valleys, and masons here later carried it into the town's bungalows and cottages.
Valdese, in Burke County, grew from 4,687 people in 2020 to 4,712 in 2025 (Census Bureau estimates), on 7.86 square miles. That makes Valdese the second-largest town in Burke County.
Valdese has about 2,400 housing units, 6 percent of Burke County's; 73 percent of the town's households own their home.

Valdese Homes and Their Attics
Stone Cottages Under Several Roofs
The town's 2022 to 2023 architectural survey found local stonemasons fitting their craft to the bungalow by the 1920s. It also found stone and brick Period Revival cottages especially common in the 1940s and 1950s. Most have a steep front gable over an arched entry, a side porch, and a chimney on an outside wall. Enclosed porches were among the most common later changes the survey recorded. Each of those parts, the entry gable, a closed-in porch or a later wing, can sit under its own piece of roof, with its own small attic or none at all. We look at each one, so no part of the ceiling is left bare.
Company Houses Above the Valdese Mill
The Valdese Manufacturing Company built houses for its workers with running water, electricity and garden plots. In 1931 it platted a mill village on the hill above the mill, though many houses there are older than the plat. The Martinat Hosiery Mill also provided houses after 1920, which the survey describes as small one-story houses with front porches. In a small one-story house, the roof drops low over the outer walls, and ENERGY STAR warns that the eaves are where a layer of insulation can thin out. Baffles hold the soffit vents open while the insulation is carried out to the wall.
Attic Insulation in Valdese
About 55 percent of Valdese's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1940 to 1969, before the state's 1978 insulation rule, about 40 percent of Valdese homes often have little insulation.
The Local Climate
Valdese's center sits about 1,210 feet above sea level, 6 miles from NOAA's Morganton station, the best match for Valdese. The station's 1991 to 2020 normals average about 3,800 heating and 1,250 cooling degree days a year, so at Valdese's station, heating needs outweigh cooling.
Readings change over short distances around Valdese: NOAA's Hickory Airport station, 10 miles away, averages about 3,550 heating degree days.
Homes by Age: What It Means for the Attic
Some 73 percent of Valdese housing units are detached single-family houses.
Built from 1970 to 1989, about 20 percent of Valdese homes may hold settled fiberglass; check its depth against the joists.

Valdese Insulation FAQs
Do the Waldensian landmarks make Valdese a historic district with rules for my house?
No. Valdese's National Register listings are single properties: the Waldensian Presbyterian Church, the elementary school, one house and two mill buildings. None is a district, and the state's 2023 roster of preservation commissions names none for Valdese. Even for a listed building, the state preservation office says the listing puts no limits on work an owner pays for privately. So nothing on the historic side stands in the way of attic work.
Does the carport roof on my Valdese ranch house need insulation?
Not while it stays an open carport. The survey found ranch houses filling whole streets here from the 1950s on, and Pons Park, Praley Street and Sunset Acres are made up mostly of them. As the ranch grew larger in the 1960s and 1970s, some gained a carport built in under the main roof. Insulation belongs over heated rooms, so an open carport is left as it is. If the carport was closed in as a room, though, its ceiling becomes part of the attic job.
Could the old insulation in a Valdese attic be vermiculite?
It could: about 35 percent of Valdese's homes predate 1960. If a Valdese 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 Valdese need a permit?
Valdese Town Hall can say whether Burke County Building Inspections, the town itself or another office handles permits in Valdese; ask before work starts.
