These roofs have two slopes on each side, maximizing the area underneath. Gambrel roofs give a clean look to a home, are easy to build, and can shorten an otherwise tall roof.

If you’re considering adding a gambrel roof to your home or outbuilding, here’s what you should know.

What is a Gambrel Roof?

A gambrel roof has two symmetrical sets of slopes on each side. The top pitch is positioned at a shallow angle, while the lower slope is steep. 

The design of gambrel roofs is simple. They maximize attic space in homes. In barns and sheds, they allow for a taller loft area. 

Gambrel roofs have a romantic, old-world look. These roofs became popular in the United States starting in the late 1600s. Builders placed them on Dutch Colonial-style homes, but they also became a staple for Georgian-style houses and farmhouses. 

You’ll also see these roofs as an accent on some mansions.

What Materials Can You Use on a Gambrel Roof?

The material on a gambrel roof typically depends on the design style. You can use any shingle, including asphalt, wood, or slate. You can also install a metal gambrel roof.

Gambrel Roof vs. Gable Roof

A gable roof is a classic-looking triangle you see in most kids’ drawings of a house. Its simple design allows water to drain off easily. And since gable roofs have sharp angles, snow doesn’t pile on them.

Gable roofs are among the simplest in design. They’re also one of the least expensive to build and replace.

Gambrel roofs come to a point like a gable but have two slopes on each side. These roofs are great at maximizing space but look more decorative than a standard gable. 

Gambrel roofs are also ideal for water drainage, but because they have a shallow top slope, they give space for snow to pile up. In extreme circumstances, this can be too heavy of a load for the roof. 

In terms of design, gambrel roofs are simple. They’re typically preconstructed, and builders assemble them in pieces. Since gambrel roofs cover a little more area, you can expect them to be slightly more expensive than a gable roof.

The Pros and Cons of a Gambrel Roof

Gambrel roofs are a simple and attractive option. But, like anything else, they have their pros and cons.

The advantages of a gambrel roof:

  • Aesthetics – Gambrel roofs can give your home an old-world romantic feel.
  • Simple Design – The simple design makes building these roofs easier and less costly.
  • Lots of Material Choices – You can use almost any roofing material on gambrel roofs.
  • Maximize Attic or Loft Space – A gambrel roof will maximize the space on your top floor.

The disadvantages of gambrel roofs:

  • Not Ideal for High Wind – Gambrels may not be the best suited if you live in an area with frequent high winds.
  • Not Ideal for Heavy Snow Loads – The shallow top slope of a gambrel roof gives space for snow to pile up. In extreme circumstances, the load can be too much weight for the roof.
