Gable Roof vs Flat Roof: Which Roofing Style is Right for You?

Gable Roof vs Flat Roof

Last Updated on April 14, 2023 by Kravelv

Choosing the appropriate roofing type for your home may be a challenging endeavor, especially if you are in the midst of developing or remodeling your dwelling. Because there is such a wide variety of choices, determining where to begin can be challenging. Gable and flat roofs are two common types of roofing, and each has its own set of advantages and disadvantages that are exclusive to themselves. In this piece, we’ll examine the similarities and differences between gable and flat roofs so that you can decide which kind is best for your house.

Gable roof vs Flat roof: Appearance

A roof with gable ends is known as a gable roof and has the shape of a triangle with two sloped sides that meet at the ridge or peak of the roof. While flat roofs have a low slope and a flat surface, with a minor inclination to allow for water drainage. Flat roofs are the most common type of roof in the United States for commercial use.

Design and Function

Gable roofs have a triangle form with a roofline that peaks in the center, which gives them their design and functional name. They are typically seen on older-style homes and may give the exterior of your house a more traditional appearance. Flat roofs, on the other hand, have little to no slope and a level surface; these types of roofs are common in modern houses. Flat roofs give more usable areas for outdoor activities, and they may be converted into rooftop gardens or patios. Gable roofs are better at shedding snow and water, but flat roofs offer more room overall.

The sloping sides of a gable roof make it easy for water and snow to slide down the surface of the roof. Flat roofs, on the other hand, need to have a very modest slope in order to maintain proper water drainage. However, this can occasionally lead to water gathering on the roof, which can lead to leaks. To summarize, regions that experience significant rainfall or snowfall are better suited to have gable roofs, whereas regions that experience a hot and dry environment are best suited to have flat roofs.

Cost and Installation

The price of a gable or flat roof, as well as the cost of its installation, is determined by a number of criteria including the roof’s size, the materials used, and the labor expenses. When it comes to installation costs, flat roofs are often more cost-effective than gable roofs. Gable roofs, on the other hand, often have a longer lifespan and require less care over the course of their lifetime.

Additional support structures, like trusses, are necessary for gable roofs, which can lead to an increase in the cost of installation. Installing a flat roof takes less time and requires less material than other types of roofs.

Because of the extra support structures necessary for the design of a gable roof, the labor costs associated with installing gable roofs are often greater than those associated with building flat roofs.

Maintenance and Longevity

In order to preserve the roof’s lifetime, both gable and flat roofs need to be maintained on a regular basis. Gable roofs have a longer lifespan than flat roofs, and they are also more resistant to damage caused by wind. Yet, because of the way they are constructed, they need far more upkeep. Because of the possibility for water to pool on flat roofs, which may lead to leaks and damage to the roof structure, flat roofs require more regular maintenance than other types of roofs.

Gable roofs are more resistant to damage caused by wind than flat roofs are, but if they are not properly maintained, they are more likely to develop leaks. Because of their lack of slope, flat roofs, on the other hand, are more likely to suffer water damage and leaks.

Flat roofs, when well maintained, can have a lifespan of up to 50 years, but gable roofs typically only endure between 15 and 30 years.

Energy Efficiency

Because of its slanted shape, which enables greater ventilation and insulation, gable roofs are often more energy efficient than flat roofs when it comes to a home’s overall energy consumption. Flat roofs, on the other hand, may be made to be just as energy efficient as gable roofs if the proper insulation and materials are used.

Gable roofs are more energy-efficient in regions that have a hot climate because they allow greater ventilation, which helps to regulate the temperature within the home. This makes gable roofs an ideal choice for homes in these regions. In regions with hot temperatures, flat roofs need to have extra insulation added to them in order to preserve their energy efficiency.

Gable Roof vs Flat Roof FAQs

Is a gable roof better than a flat roof?

Gable roofs are significantly superior to flat roofs in terms of drainage and stability in the event of heavy rain. Gable roofs also give more stability. On a sloped roof, the water flows off smoothly and in a consistent manner, but on a flat roof, water might pool and put pressure on the structure of the building.

Is a flat roof cheaper than a gable?

When it comes to installation costs, a flat roof is far more cost-effective than a gable roof. This is due to the fact that it uses fewer resources and has a more straightforward structure.

What are the disadvantages of a gable roof?

Gable roofs often have a very tiny overhang from the front of the house, which, in regions that see significant wind speeds, can cause the roof to peel away from the building. Gable roofs, due to the manner in which they are constructed, also run the risk of collapse. It is possible for the roof to collapse if the framework that supports it is not constructed with sufficient sturdiness by the builders.

Where are gable roofs most used?

In colder areas, you are most likely to see a gable roof. These are the classic roofing type of homes found in New England and throughout the east coast of Canada in general. The type of roof will be familiar to readers of popular fiction in both nations thanks to its appearance in such works.


The gable roof and the flat roof are two common roofing types that each have their own set of advantages and disadvantages. In order to make an educated choice regarding the type of roofing to install, homeowners should take into consideration a number of different factors, including the design and function of the roof, the cost of the installation, the amount of maintenance required, the lifespan of the roof, and its energy efficiency.

Go to a professional roofing contractor if you are still unclear about which roofing type will work best for your house. They will be able to give you expert advice and direction. Keep in mind that purchasing a roof of superior quality will not only add value to your property but also shield it from the effects of the weather for many years to come.

In the end, the roofing type that is ideal for your home will be determined by factors such as your personal tastes, your financial constraints, and the requirements of your property.
