What is a Gable roof?
A gable roof is a type of roof with two slopes on two different sides. A gable is a triangular shape that forms the top of an exterior wall. In a building, a gable roof may also be called a Dutch roof.
Because of the simple design of the roof timbers and the rectangular shape of the roof sections, gable roofs are very common. This avoids details that take a lot of time or money.
An asymmetrical gable roof is one in which the pitch or rafter lengths of the two roof sections differ. In Switzerland, a gable roof on a church tower (gable tower) is known as a ‘cheese wedge roof’.
Because of its adaptability, the gable roof is used in various parts of the world. Gable roofs with a steep pitch are used in areas with high winds and heavy rain to avoid water penetration.
In alpine settings, gable roofs have a shallower pitch that supports snow better, lowering the risk of an uncontrolled avalanche and making it easier to preserve an insulating layer of snow.
What Is the Purpose of A Gable Roof Design?
Gable roofs are used primarily as decoration on houses and barns, but they are widely used in commercial construction for commercial warehouse buildings and garages because they provide better ventilation in the summertime than pitched roofs.
The most traditional gable is formed by sliding two triangular pieces of plywood over the sloped edge of an exterior wall to form the triangular top shape of a house or barn.
The triangular shape is an efficient use of building space, with a high ceiling at the bottom, a relatively low ceiling at the top, and a large surface area that can accommodate windows.
A gable roof can be built from two triangular pieces of wood and a stringer for longer spans.
The stringer is an engineer’s term used to describe full-length supports that span the entire width of the roof. Modern houses have gable roofs that are often constructed with metal gutters and trims or wood shingles.
Different Types of Gable Roof Designs
Gable roofs are a popular roofing option for many properties, with a variety of design options to select from.
Choosing the right roof for your property is important for both aesthetics and functionality, so we’ve put together a guide to the different types of gable roofing designs here.
A gable roof is a common roof type used for many building designs. It will have two sloping sides that meet to form a ridge, and is most easily identified by the triangular shape formed at either end.
Gable roofs are an ideal design for areas with cold weather conditions as they can easily shed water and snow, however they can prove problematic in high wind areas if the frames do not have adequate support.
Gable roofs are also a suitable option for those looking for increased headroom in a loft conversion, and for better ventilation to the attic area.
There are several variations of the standard gable roof, including:
Box Gable Roofs
Box gable roofs have a triangle expansion at either end of the house, with the roof portion boxed in at the bottom. This design is very similar to the typical gable roof; however, the triangle element of the design stands out more.
Front Gable Roof
A front gable roof is simply located at the front of the home, with the entrance door often located beneath the gable.
This is a frequent element in Colonial-style homes, but it is also becoming more fashionable as a design.
The front door of the building is normally positioned on the front side under the gable in this style of gable roof.
Cross Gable Roof
A cross gable roof is made up of two or more gable rooflines that meet at an angle, usually with the two ridges perpendicular to one another.
Because of the effect a cross gable roof has on the construction of a house, houses with this style frequently have a more complex plan.
Homes with a cross gable roof, for example, may have distinct wings, a wider porch, or an attached garage.
Dutch Gable Roof
A dutch gable roof is a cross between a gable and a hip roof. The traditional design places the gable roof on top of the hip roof, creating greater room within the loft.
This is a popular design among home owners since it improves the aesthetic appeal of a home while also giving the practical function of additional room.
Gable Roof Advantages and Disadvantages
Gable Roof Advantages

6. Gable roofs are resistant to water penetration
A gabled roof has a floor that sits on the ground, creating a barrier between the residents in your home and precipitation water.
The sloping sides of this roof provide an additional barrier that can prevent additional moisture from entering your home through joints or penetrations into your siding.
Gable roof structures easily shed water and snow which makes them great for areas with heavy snowfall. The steep pitch of gable roofs allows for excellent water drainage and fewer leaks.
7. Gable roofs are lighter than other roofs
Gable roofs are lighter weight than comparable pitched roofs and require less structural support since the internal load is distributed along the length of the roof rafters.
8. Gable roofs are hurricane resistant
Gable roofs are strong against high winds and heavy rains as they have a form of natural ventilation, which allows the attic space to release hot air and moisture.
9. Gable roofs can be built with small spaces
If you have a small space to build, but need a large structure, gable roofing is the perfect solution for this dilemma.
Because Gable Roofs have two sides, they can be constructed at a slope that is suitable for the available space.
10. Gable roofs suit all types of architecture
Gable roofs can complement all styles, from modern to traditional. The two sloping sides of this roof style allow it to be used on homes with multiple architectural styles or on projects such as custom homes or renovations.
11. Gable roofs are low maintenance
The triangular shape of a gable roof makes it easier to manage than sloped roofs. The triangular shape is able to shed precipitation, including snow, in a way that causes minimal damage.
12. Gable roofs are safer than other types of roofs
Because gable roofs generally have lower ceilings than other roof designs, they are less likely to be an attractive target for burglars.
13. Gable roofs are less likely to leak
Gable roof designs support the maximum possible weight of the roofing material in a given span. This reduces the possibility of leaks, which can be very costly to repair.
14. Gable roofs need much less maintenance than other types of roofs
Gable roofs require much less maintenance than pitched or sloped roofs, such as keeping trim and caulk in good shape. Because they have a lower pitch than most other roof styles, they also require less upkeep.
15. Gable roofs provide more interior space
The triangular shape of a gable roof provides more space under the roof structure than a sloped roof. This can be an advantageous space for storage or even future room additions.
16. Gable roofs are energy efficient and environmentally friendly
The sloping sides of Gable Roofs provide cover for the home and help to reduce energy costs, helping to save money on utility bills, which is an additional cost-saving.
17. It provides more space for an attic
A gable roof provides more space for an attic than a hip or flat roof would.
18. Gable roofs look good on any style house
Due to the simplicity of the gable roof, it looks good on almost any style of home. It is hard to choose which part of a house looks better, the roof or the rest of the house.
The disadvantage of Gable Roof
1. Gable roof is not suitable for windy and hurricane areas
Because the gable roof has only two sides, it will be open to wind damage. High winds can be an issue for gable roofs if they are not properly built, especially if there is too much overhang, in which case the entire roof could be blown off.
2. Gable roofs are no quite beautiful
Gable roofs do not have the same aesthetic appeal as a hip or flat roof as they do not lay in a smooth line and do not offer the same architectural appeal that other roof types can.
3. Gable roofs do not work with low-slope roofs
Gable roofs are only able to be placed on homes that are at least 30 degrees or higher in slope. A Gable roof must have a greater than 20-degree slope to fit the triangular shape of a gable.
