Black and white barndominium exteriors: color ideas, heat and fading

A black barndominium looks sharpest with warm accents, such as cedar, stone or a wood door, and black windows. A white barndominium gets its contrast from a black or charcoal roof and black trim. The finish deserves as much attention as the color, though: dark panels absorb more sunlight, show metal waviness more and depend on a warranty with real fade limits, so ask for the numbers before you choose.

A note on our plans. The colors in our images are illustrative concept renderings. You choose and confirm real panels, paint and finishes with your builder and the product maker. A plan set costs $149, is unstamped and is drawn for conventional wood framing. See what a plan set includes.

Black: what to know before you commit

Dark colors change three things: how much heat the surface absorbs, how visible metal waviness is, and how much fade you can see over the years.

Heat

The U.S. Department of Energy (DOE) says traditional dark-colored roofing absorbs sunlight and passes that heat into the home, while a white or special "cool color" roof can reflect up to 90% of the sunlight that hits it. DOE says a cool roof can cut a single-story building's annual air-conditioning use by up to 15% in warm or hot climates, and that savings vary and are greatest there. A cool roof can also raise winter heating needs. The Environmental Protection Agency (EPA) says that penalty is typically offset by summer cooling savings, and that it is smallest where snow covers the roof for much of the winter.

The color's name does not tell you how it performs, because special pigments can make a dark color reflect more. One metal building maker's PVDF color chart (notice dated December 3, 2019) lists an initial solar reflectance of 0.72 for its Regal White and 0.27 for its Midnight Black, with a solar reflectance index (SRI) of 88 and 26. Its Charcoal rates 0.32 and 34. The chart treats a solar reflectance of at least 0.25 as the minimum for a "cool" product, and says a higher SRI means a lower surface temperature. Ask the panel maker for the rated values of the exact color you choose. DOE's guide points to the Cool Roof Rating Council's directory of rated products.

Walls count too. EPA says cool walls, made reflective with white or light-colored paints or cladding or with special pigments, can cut heat and energy use much as cool roofs do in U.S. climate zones 1 to 4, especially on older walls that are less insulated than roofs. EPA also advises pairing a cool roof with insulation and air sealing to get the most from it.

Waviness and movement

On a flat metal panel, "oil canning" means visible waviness. The Metal Construction Association (MCA) says it is more noticeable on darker panels, because a dark panel shows a bigger difference in reflected light than a lighter one does. MCA calls it generally an aesthetic issue that typically does not affect structural integrity, and it lists thicker metal, stiffening ribs in the profile and low-gloss finishes as ways to reduce it or make it less apparent.

Heat also makes panels move. MCA says a panel's surface temperature may be more than 100 degrees higher than the air temperature, so fasteners, clips and edge connections must be designed and installed to let the panel expand and contract. Green Building Advisor makes the same point about any cladding: darker colors heat the material more, which increases movement. Ask whoever installs your panels how they will allow for it.

Fading and finish warranties

Green Building Advisor says most exterior finishes chalk to some degree and lists fading as another issue with dark colors, and good finishes come with ratings. One panel maker's data sheet for a PVDF finish (October 2025) says that under normal atmospheric conditions the finish will not crack, flake, chip or peel for 45 years, chalk beyond a #8 rating for 35 years, or fade more than 5 Hunter units for 35 years. Hunter units measure color change (ASTM D2244). The same sheet excludes corrosive environments such as standing water, saltwater, dissimilar metals and animal waste. A metal building maker's 2019 color chart lists a 35-year finish warranty on its standard PVDF colors and 25 years on its silicone-polyester colors, and notes that PVDF is a slight upcharge over silicone-polyester.

Warranties differ by maker, finish, color and site, so read the one for the exact panel you will buy. Look for the fade limit, the chalk rating, the number of years and the exclusions.

White: reflectance, wood and stone

White and light colors reflect the most sunlight. DOE says white roofs are coolest, with cool colors a popular alternative for roofs neighbors can see. Even whites differ: the chart above rates its three whites between 0.63 and 0.72, so ask for the exact number. Lighter panels also hide waviness better than dark ones, according to MCA.

Many white and black designs add cedar. The USDA Forest Products Laboratory says wood used outdoors needs protection from water, sunlight and weathering, and that bare wood weathers to a silvery gray. Decide early whether the cedar on your home will be finished and renewed or left to age. The Blackwood's entry is cedar-lined, and the Roadhouse RV and the Gathering Barn carry cedar accents.

Roof, siding and trim: what to match

• Decide the roof first. DOE and EPA focus on roofs, and the roof color sets the tone for the walls and trim.
• Windows and trim. Black frames sharpen a white body, as on the Whitfield. The Blackwood goes the other way, with floor-to-ceiling black windows in charcoal-black metal.
• Warm accents. Cedar soffits and a cedar-lined entry on the Blackwood, and cedar accents on the Roadhouse RV, add warmth to dark metal.
• Stone and brick. A limestone base on the Lone Star Wrap and a whitewashed brick base on the Magnolia Split anchor a light body.
• Gloss. One panel maker lists a standard gloss range of 20 to 35 and a low-gloss range of 8 to 15, measured at 60 degrees, for its PVDF finish. MCA says lower gloss makes waviness less noticeable.
• Porch posts and ceilings. A porch repeats your colors up close, so see our porch ideas before you fix them.

Color and the land

The setting can make the choice for you. The Overlook's dark bronze siding lets the home disappear into its hillside, and the Timberline sets taupe siding and a bronze roof into a wooded lot. The Blackwood suits a wooded lot too, with every room looking out to the trees. When neither black nor white fits, our plans show other palettes, such as sand-beige siding with a dark bronze roof on the Sandhill and forest-green siding with natural cedar on the Loon Lake Retreat.

Local rules and your own site

Minnesota's Department of Labor and Industry notes that local zoning ordinances may limit the use of metal exterior finishes. Neighborhood covenants may set exterior colors as well, so check both before you order panels. Our site-first guide lists what else to read on a parcel.

A checklist before you order panels

1. Look at large samples outdoors in morning, noon and evening light, on the side of the house they will cover.
2. Ask for the rated solar reflectance of the exact roof color.
3. Ask for the finish warranty for that color: fade limit, chalk rating, years and exclusions.
4. Ask the installer how they will allow for thermal movement, and which gauge and profile reduce waviness.
5. Ask the window maker about warranty terms for dark frames.
6. Plan the cedar: finished and renewed, or left to age.
7. Check zoning and covenants for material and color rules.
