Gable Roof – What It Is, Pros/Cons and Variations  

Gable roofs are one of the most common roof types in Canada, and also in the United States. To understand the gable roof though, we first need to understand something about what a roof is. A roof, as the name suggests, is a covering installed over a building’s structure that protects its occupants from rain, snow, hail, and other unwanted weather conditions. This covering is often installed over the structure with the help of supporting walls and trusses, which form an arch, or shape, between the structure and the covering. A gable roof can vary in type and style, which will determine its purpose and how it is secured to the structure.

The gable roof is a centuries-old design that is utilized by many homeowners, but has only recently gained traction among home remodelers and architects. ​ The first thing a gable roof is noticed for is its steep pitch, which leads to a more open, airy feeling for the area it covers, which is usually the most prominent part of the house, such as the area where a deck is located.

The gable roof is one of the most common roof designs in the United States. This kind of roof form is often seen in ranch-style houses and is a popular design in Cape Cod, New England. The majority of these houses include garages, front porches, or dormers with gable roof structures, which contribute to their aesthetic appeal.

If you’re framing your roof or constructing a new one, a gable roof is a good option. We’ll go through the many types of gable roofs, as well as the benefits and drawbacks of each, to help you make your choice.

What is the meaning of a gable roof design?

Gable roofs were originally introduced to the United States in the early 1600s. In colonial times, the bulk of ancient houses had gable roofs. This kind of roof has a flat-faced shape, similar to an A. A gable is a roof with a triangle end-shaped form. To complement the home’s outside, its triangle end is constructed of siding or stone. 

A gable roof may have one or many gables, but they nearly always have two sloping sides that create a triangle-shaped ridge. 

Gable Roof’s History

Gable roofs were popular in Ancient Greece in the 1600s, when they were used for temple roofs. These architectural elements quickly gained popularity in North America and Europe. Gable-fronted structures were popular in Germany throughout the medieval gothic period. In the early nineteenth century, these roof variants were popular in the United States. The side-gabled roofs were popular throughout the Renaissance era (between the 14th and 17th centuries) because they were influenced by Italian architecture.

The Benefits of Gable Roofs

Affordability

A gable roof is a more cost-effective choice if you’re on a limited budget. Because of the simplified form of this roof, the total installation costs are considerably cheaper when compared to other roof types such as mansard. This is the most significant benefit of gable roofs, which is why they are more common than hip roofs. Because a gable roof has just two roof planes instead of four (hip roofs have four! ), you’ll save money on siding. 

More Attic Room

A greater attic space is an advantage of gable roofs. This is excellent for expanding families that need more roof space to convert into a playroom or bedroom for their children.

Various Material Choices

When building a gable roof, you have a lot of material choices. You may construct and supplement the roof with just about any tile material, from clay tiles to metal sheets to concrete shingles, depending on your needs.

Gable Roofs Have Some Drawbacks

Protection against the wind

Gable roofs don’t fare as well as hip roofs when it comes to weather resistance. This is due to the roof’s flat surface, which is vulnerable to wind damage. The strong force of the wind may pull up the roof’s truss or lift the roof away from the home’s walls if the gable has an overhang. As a result, this roof design is not suggested for hurricane-prone regions. If strong winds are a problem, limit the roof overhang to less than 30 inches. However, you should always consult an architect or a roofing expert if you have any concerns. 

More difficult to construct

Unless we compare them to mansard roofs, gable roofs are more complex to construct. Because of the various heights of the roof form, such houses are more difficult to build. They may also need additional brackets to improve their wind resistance. This is a time-consuming process that requires installation expertise.

Gable Roof Designs in 8 Different Styles

There are numerous different types of gable roofs, including: 

Box Gable

The roof of a box gable features a triangular extension at each end and a boxed portion at the end. This gable roof stands out more than the conventional gable roof because it is more distinct at the triangular portion of the design. 

Gable of the Cross

A cross gable roof is defined by the intersection of two or more gable-shaped roof lines. Two ridges placed in perpendicular portions are common in these rooflines. Because of the unique form of the roof, homes with a cross gable roof typically have a more complicated layout. A wide porch, an attached garage, or separate wings may be included in such homes.

Gable on the Front

A front-gabled roof is placed at the front of a house, as the name implies. As a standard feature, the entrance door is usually positioned directly under the gable. On Colonial design houses, this gable roof variant is common. 

Gable on one side

Unlike the front gable, which is located in the front of the house, the side gable is located on the gable roof’s side. It is made up of two equal panels that are pitched at an angle. 

Gable, Dutch

This architectural variant, which is a hybrid of a hip and gable roof, consists of the gable being placed on top of the hip roof to provide extra room inside the attic. Families like a dutch gable because it provides greater room. This practical gable form also adds to the home’s visual appeal.

Shed Roof on a Gable

Shed gable roofs have three slanted dormers in one direction. These are also known as half gables, and they’re simple to construct since the rafters are all the same size. 

Gambrel

A gambrel roof is a gabled variant of a mansard roof. Barns and old structures are often linked with this variance. The roof is divided into two parts, one of which is near to the crest and the other of which is quite level. For optimum utilization of the attic space, the ridge closest to the eaves tends to slope down sharply.

Saltbox

The saltbox shape is a classic Colonial-style gable roof. This is an open gable with one end of the roof extending farther than the other. A saltbox roof is an asymmetrical roof style that provides much more space than a traditional gabled roof.

What’s the Difference Between a Gable and a Hip Roof? 

A hip roof lacks vertical wall space that reaches to the peaks. It’s more likely to be slanted on both sides, creating a ridge between neighboring slopes, hence the name hip. On a hip roof, there are four sloped sides and one horizontal ridge on top. A gable roof, on the other hand, has just two slanted sides.

It all depends on the weather conditions in your area, how much room you need, and how much you want to spend on roof construction when choosing which is best for your new house.  

In wet and snowy weather, both gable and hip roof styles perform well. This is due to the roof trusses’ great strength, which can easily withstand the weight of the snow. A gable roof, on the other hand, may shed snow more easily than a hip roof. However, if you reside in a high-wind area where hurricanes are a possibility, a hip roof will be a better choice.

Hip roofs are constructed of more structurally sound materials and have a lower pitch, making their surfaces less susceptible to strong winds. Gable roofs, on the other hand, have a greater pitch and are more likely to have their shingles lifted off by strong winds. This is why it’s critical to make sure your gable roofing material is of the greatest quality and that the installation is done by experienced roofers. After all, in the case of strong winds or storms, the gable roof may easily collapse due to insufficient bracing.

The extra living or storage space beneath the roof is perhaps the most significant benefit of gable roofs over hip roofs. Although hip roofs have a lower attic ceiling, the area cannot be used for residential reasons. This extra storage area in the hip roof is solely for storing purposes. A gable roof, on the other hand, offers a lot of room for living and storage. For optimum light in the attic, all you need to do is add some windows to your gable. 

How Much Does a Gable Roof Cost to Install?

Building a gable roof is often less costly than many other roof designs. The cost of labor varies from $7 to $15 per square foot. So, on average, a 2,000 square foot roof will cost $14,000. Depending on your needs, adding dormers or gables may increase the cost.

What is the Average Gable Roof Lifespan?

Many variables must be considered while estimating the lifetime of a roof, including the quality of the installation, materials used, weather conditions, and so on. The average lifespan of a gable roof is approximately 30 years. However, if an appropriate supporting structure is utilized in the roof’s construction, it may endure much longer.

Gable roofs, also known as “French roofs” or “German roofs”, can provide a variety of advantages over traditional roof styles.. Read more about gable and valley roof and let us know what you think.
