Metal Building Colors: How to Choose a Color Combination You Will Still Like in 20 Years

Size, roof style and doors get most of the attention when people design a steel building. Then, at the very end, comes a question that turns out to be harder than expected: what color? Metal building colors are not just decoration. The building will sit in view of your house, your neighbors and every future buyer for decades, and the panels are not something you repaint on a whim. This guide gives you a simple way to choose a combination you will not get tired of.

The three colors on every building

A steel building has three color decisions, and thinking of them separately makes the choice easier:

• Roof. The largest surface seen from a distance and from second-story windows.
• Walls. The main body color, and the one that has to sit comfortably next to your house.
• Trim. The outline: corners, eaves, door and window frames. Trim is where contrast comes from.

We offer 20 color options, including a range of grays, whites, reds and blues, and you can mix panel and trim colors to match your property. Carports have a roof and trim only, unless you add side panels.

Start with what is already on your property

The safest way to pick a building color is to borrow from what is next to it.

1. Match or echo the house roof. A building roof in the same color family as the house roof makes the two read as a set, even when the wall colors differ.
2. Pick walls that agree with the house siding. They do not need to be identical. A shade lighter or darker in the same family usually looks more deliberate than a near-miss.
3. Use trim to tie it together. Repeating the house trim color on the building is the easiest way to make a new structure look like it has always been there.

On rural properties with several outbuildings, consistency matters more than any single color: one roof color across every building looks planned.

Classic combinations that age well

• One color, contrasting trim. For example, gray walls and roof with white trim. Clean, and the trim sharpens the lines of the building.
• Light walls, dark roof. A traditional look that grounds the building visually and suits most homes.
• Barn red with white trim. The familiar farm scheme. It looks at home on agricultural buildings and barn-style garages across the Midwest.
• Dark walls, matching dark roof. A modern look that is popular on workshops and barndominiums, especially with lighter doors for contrast.
• Two-tone with wainscot. A band of a second color along the bottom of the walls, described below.

Two-tone buildings and wainscot

Wainscot is a band of contrasting panels along the lower part of the walls, usually around three feet high, with the main wall color above it. It does three useful things: it breaks up a tall, plain wall; it puts a darker, more forgiving color where mud and mower clippings hit; and it makes a garage or shop look more like a finished building than a shed. Several of the garages we install are designed with wainscot, in both horizontal and vertical panel layouts.

A good rule: use a darker color for the wainscot than for the wall above, and match the wainscot to the roof or the trim so the building uses no more than three colors in total.

Light vs. dark panels: what changes besides looks

• Heat. Lighter colors reflect more sunlight and stay cooler; darker colors absorb more. In an uninsulated building this is noticeable in July. Insulation narrows the difference — see our metal building insulation guide.
• Snow melt. A darker roof warms faster on a sunny winter day, which can help snow release sooner. Roof style matters more than color here: a vertical roof sheds snow far better than a horizontal one.
• Dirt and scratches. Mid-tones such as gray and tan hide dust and water marks best. White shows dirt; very dark colors show dust, pollen and fine scratches.
• Fading. All painted finishes weather over time. Fading tends to be more visible on deep, saturated colors than on lighter neutrals. Our buildings carry a paint warranty; the warranties are listed on the FAQ page.

Check the rules before you fall in love with a color

Some subdivisions and homeowner associations have covenants that require outbuildings to match the house or limit the palette. A few municipalities have appearance standards for accessory buildings as well. It takes one phone call to find out, and it is much easier to make that call before the building is ordered.

How to test a combination before you order

• Build it in 3D. Our 3D estimator lets you switch roof, wall and trim colors on your actual building and see the result from every side.
• Look at real buildings. Colors read differently at full size and in daylight. Browse the gallery for combinations on finished projects.
• Ask about samples. Screen colors are never exact. Compare the color chart or a sample against your siding outdoors, in sun and in shade.
• Decide on the doors last. White doors are the common default; choosing a door color that matches the trim or the wainscot looks more custom.

Frequently asked questions

What is the most popular color for metal buildings?

Neutrals such as white, gray and tan are consistently common because they suit most houses and landscapes. Red remains a favorite for barns and farm buildings.

Do dark metal buildings get hotter?

Dark panels absorb more solar heat than light ones, so an uninsulated dark building runs warmer in direct summer sun. Insulation and ventilation reduce the difference.

Can I choose different colors for the roof, walls and trim?

Yes. Roof, wall and trim colors can be mixed, and a wainscot band can add a further accent.

Can a metal building be repainted later?

It can, with proper preparation and paint made for coated metal, but it is a significant job on a full building. It is better to choose a combination you are confident in from the start.
