A gable roof is one of the simplest and most common roof designs, featuring two sloped sides that meet at a peak to form a triangle. Thanks to their straightforward construction, gable roofs are often more affordable, typically costing $6 to $9 per square foot, or about $9,000 to $13,500 for a 1,500-square-foot roof.

What Is a Gable Roof?
A gable roof is one of the most common roof styles. It’s easy to spot by its triangular shape. Imagine a simple rectangular house with two sloping sides that meet at a peak — those sides form the gables.
This roof style has been around for centuries. The Ancient Greeks used it, and it became popular in Europe before making its way to the U.S. Today, it’s still a top choice because it’s affordable, easy to build, and works well with prefabricated trusses.
Gable roofs come in different slopes, called pitches. A 3:12 pitch means the roof rises 3 inches for every foot it extends. Most have pitches between 3:12 and 6:12, which are easier to build and maintain.
Pros”]Styles of Gable Roof
There are several styles of this roof type. Each design offers unique benefits and visual appeal depending on your home’s layout and location.
Open Gable
This is the most basic and widely used gable design. The triangular shape is fully visible at the sides of the home. It’s straightforward to build, especially when using identical manufactured trusses.
Cross Gabled
This style features two or more gable rooflines that intersect, often forming valleys where the slopes meet. It’s ideal for homes with a more complex layout, like additions or separate wings.
Gambrel
A gambrel roof has two slopes on each side, with the lower slope steeper than the upper one. It provides additional headroom or attic space, often seen in barns and Dutch Colonial homes.
Box Gable
This design is similar to an open gable, but with boxed-in eaves that extend slightly beyond the walls. The box shape emphasizes the gable’s triangular form for extra curb appeal.
Dutch Gable
A Dutch gable combines a hip roof with a small gable on top. It offers more loft space and can include windows for natural light. These roofs are more complex and may require extra planning.
Saltbox Gable
This asymmetrical roof features one short slope and one long slope, giving the home a “lean-to” look. It’s commonly found in Colonial-style architecture and works well in snowy regions.
Best Materials for Gable Roofs
Gable roofs work with nearly any roofing material. Your choice often depends on your budget, climate, and desired look.
Popular options include:
- Asphalt shingles: Affordable and easy to install.
- Metal roofing: Durable and great for snow and rain runoff.
- Clay or concrete tiles: Stylish and long-lasting, especially in hot climates.
- Wood shakes or shingles: Natural aesthetic, though they require more upkeep.
- Slate: A premium option with excellent longevity, but heavy and expensive.
When selecting materials, consider your region’s weather, maintenance requirements, the roofing cost, and your preferred style.
Cost of a Gable Roof

The average cost to build a gable roof is $6 to $9 per square foot, or $9,000 to $13,500 for a 1,500-square-foot home. Factors that can impact your price include:
