What is a gambrel barn?
A gambrel barn is a type of structure traditionally used for storage on farms and ranches. The structure features a gambrel roof, which is a design that uses two different slopes on each side of the roof to maximize internal storage space while still taking advantage of the sloped roof’s ability to shed water and snow.
How does a gambrel roof work?
A gambrel roof is one that has two sides to it. Each one offers a shallower slope that sits above a steeper one. Most designs are symmetrical, providing the advantages of a sloped roof while still maximizing the amount of space inside of the building.
What are the advantages of a gambrel roof?
Like mansard roofs, gambrel roofs allow additional space for an extra floor or garret. It’s for this reason that gambrel roofs are so popular among barns and sheds. They can provide additional storage without taking up any additional space.
What is the difference between a gambrel and mansard roof?
Both gambrel and mansard roofs have two different slopes. The main difference between the two is that the mansard roof has four sides, while the gambrel roof has only two. They have the same advantages, although their final appearance is slightly different.
What is a gambrel Colonial?
The Gambrel features the typical two-sided roof but with two slopes on each side; the upper slope is positioned at a shallow angle, while the lower slope is steep.
Who invented the gambrel?
History of Gambrel Roofs The origin of the gambrel roof in North America is unknown. However, the oldest example of a gambrel roof was built in 1677, on the second Harvard Hall at Harvard University in America. The oldest surviving house that dates back to 1677-78 with a gambrel roof in the U.S belongs to Peter Tufts.
What is a gambrel shed?
What are Gambrel Sheds? Gambrel sheds, also called barn sheds, combine traditional styling with generous overhead storage space. The roof on a gambrel shed has two slopes on each side of the ridge with a steeper, lower slope, providing extra headroom.
What are the different options for creating a gambrel roof?
There are three types of gambrel roof you can get today:
- Classic: This is the most common gambrel roof design, which is often seen on barn and shed roofs.
- Mansard: This is a French-style roof that has an identical shape to a gambrel.
- Wall-supported: If you want the most beautiful gambrel roof, this one’s for you.
How does a gambrel roof look?
It has the appearance of a sloped roof, but the slope of the top sides are not as steeply sloping as the bottom sides. A gambrel roof is sometimes also known as a dutch colonial roof, and while the origins of the gambrel roof are unknown, it can be seen on barns and houses from the 1600s onwards in North America.
What is the difference between a gable roof and a gambrel roof?
The Gable shed roof is a simpler design with slightly more open areas on the outside walls, leaving your walls slightly more exposed to the elements.

What are the angles of a gambrel roof?
What are the angles for a gambrel roof? Gambrel roofs are symmetrical two-sided roofs, with two slopes on each side. The lower slope is positioned at a steep angle while the upper slope tends to be more shallow. For a standard gambrel roof, the peak is built at a 30-degree angle with the second slope at 60 degrees.
How is a gambrel roof supported?
Also, most gambrel roofs require a kneewall to support the knuckle, or the joint between the upper and lower roof slopes. You have to build the kneewall first, then brace it straight and work around the wall and its braces while installing two sets of rafters.
What pitch is a gambrel roof?
Determine a pitch for the top slope of the gambrel roof, the rise in inches per foot from the midpoint connection to the peak; 7/12, or a rise of 7 inches per foot, is a common top gambrel pitch. Reverse that for the bottom angle; make that pitch 12/7, a drop of 7 inches per foot from the connection to the wall.
Where are gambrel roofs most common?
