Two of our most popular roof styles are the American Barn and the Gambrel, and we get questions about the difference between them pretty regularly. From a distance they can look similar — both have that classic barn silhouette that people love. But they're different structures with different strengths, and the right choice depends on what you're building and what you want to do with the space.

Here's a clear breakdown of both.

The American Barn

The American Barn style features a distinctive roof with a steep lower pitch and a shallower upper pitch, creating the broad shouldered profile that most people picture when they think of a classic American barn. It's one of the most recognizable building silhouettes in the country for good reason.

The upper portion of the American Barn sits vertically, almost like a small additional story above the main roofline. This vertical section is what creates the extra wall height and loft space that the style is known for, and it's also where windows are often placed for natural light and ventilation.

The Gambrel

The Gambrel roof has two slopes on each side, with the lower slope being steeper and the upper slope being shallower. This design originated in Europe and became extremely common in colonial American architecture. It's the roof you see on classic New England barns and farmhouses.

The genius of the Gambrel is efficiency. The steep lower slopes push the walls outward before the roof begins to angle in, which creates significantly more usable upper-floor or loft space compared to a simple gable roof of the same footprint. If you're planning a two-story layout or a large loft area, the Gambrel is often the more practical choice.

So Which Should You Choose?

If you're building a large open-use structure, a commercial building, or a barndominium where ceiling height and drama are the priority, the American Barn is hard to beat. It makes a statement and gives you a lot of open interior volume to work with.

If you're building a residence and you want to maximize your livable square footage, especially on an upper floor or loft, the Gambrel is usually the smarter choice. The roof shape naturally creates more usable space above the main level without requiring a larger footprint.

We've built hundreds of both across the country and we've seen them used in ways that might surprise you. The best building is the one that fits your life, your land, and your budget. We're here to help you figure out which that is.
