Types of Pergola
There are two primary types of pergolas, the gable roof, or the flat/skillion roof. Each has its advantages. In choosing what type of pergola you want for your home it’s best to consider its purpose. You can also get creative with the shape of your pergola, the most common pergola shape is the rectangle, however you can have L shaped and T shaped pergolas as well as pyramids, or you can combine flat and gable pergolas in any number of combinations.
Gable roof pergolas offer a light and cool environment as they have a higher roof with open ends to allow for airflow. On a Gable pergola the rafters are cut at angles and meet in the centre of the structure at a ridge. Gable pergolas can mirror the roofline of your home and blend into its architectural style. You can also amend the end types on a gable pergola to give it hip and bay ends to further customise its design. Gable pergolas can be lined with timber or materials that emulate ceilings, they can also have decorative additions to them such as false gables and dutch gables which allow for more space under the roof and give a different appearance to the roof line outside of the structure.
Flat/Skillion roof pergolas are highly versatile structures that can provide a lot of flexibility. They can be lined with a timber ceiling and feature inbuilt lighting and fans, or they can have different levels or pitches to provide exactly the style and conditions you require. A flat pergola using standard roof sheeting is recommended to have a 5 degree pitch at a minimum so water can remove itself from the top of the structure. If needed there are heavy duty roof sheets with extremely high profiles that can allow for a lower pitch but generally these are not recommended on your average backyard pergola.
Both flat and gable roof pergolas can be attached on one or multiple sides to your home. Attachment methods used are determined by the pergola type as well as the characteristics of your home. Some pergolas can be bolted to the wall, however in most cases we recommend using brackets to connect the pergola to the roof of your home and reduce the load that the pergola places on your home.
Pergolas can also use different types of roofing to achieve different ends. Primarily, pergolas are covered with either colorbond® roofing or polycarbonate roofing which either mirror the style of your home or allow good light transmission into the pergola. You also have the option of tiling a pergola or adding a ceiling out of many different materials. These finishes allow you to add things such as fans, heaters and lighting to make the most of your pergola in all conditions.
