Trusses vs Rafters: Which to Use for Raked Ceilings

When building a house with a raked ceiling, the choice between roof trusses and roof rafters is a significant one. It will affect the structural integrity of your home and the overall look of your ceiling. Your choice of roof structure will also likely impact the overall cost of your project!

As the leading supplier of roof trusses in South East Queensland, King Truss understands this decision and can help you make an informed choice. Keep reading to find out how roof trusses and rafters differ and which might be the better choice for your construction project below.

What are Raked Ceilings?

Raked ceilings, also known as cathedral ceilings or vaulted ceilings, are a popular design feature in modern homes. These ceilings slope upwards towards the roof’s peak, creating a spacious and open feel to the room. They can be a great way to add visual interest to a room and make it appear larger than it is.

However, building raked ceilings requires careful consideration of the roof structure and the materials used to support it.

What are Roof Trusses?

Roof trusses are pre-engineered triangular structures made of timber or steel. They are designed to provide support for the roof’s weight and transfer it to the house’s walls. They consist of interconnected triangles that provide strength and rigidity to the roof structure. Trusses are designed and manufactured to fit the specific dimensions of your roof, ensuring a perfect fit and optimal structural integrity.

King Truss is South East Queensland’s premier provider of timber roof trusses.  Timber trusses have many benefits over steel trusses and at King Truss, we use locally sourced timber, a sustainable building material.  For more benefits on timber vs steel, trusses see our blog:

Trusses offer several advantages over roof rafters. Firstly, they are pre-engineered, ensuring structural integrity and reducing the risk of failure. Trusses are also stronger and more rigid than rafters, providing better support for the roof’s weight and reducing the risk of sagging over time. Additionally, trusses can span longer distances than rafters, reducing the need for interior support walls and creating a more open and spacious feel to the room. Finally, trusses are faster and easier to install than rafters, reducing labour costs and project timelines.

What are Roof Rafters?

Roof rafters are individual timbers that span from the house’s walls to the roof’s peak, supporting the roof’s weight. They are not pre-engineered and require an engineer’s design to ensure structural integrity. They are more traditional and are commonly used in older homes. Rafters can be made from a variety of materials, including timber and steel, and come in a range of sizes and shapes to suit the specific needs of your roof.

While roof rafters can be used for raked ceilings, they do have some limitations. Firstly, they require an engineer’s design to ensure that they are structurally sound and able to support the weight of the roof – which is usually done during the construction work itself. This can add time and expense to the construction process. Additionally, rafters are not as strong or rigid as trusses, and they may be more prone to sagging over time. Rafters are also not able to span as long a distance as trusses, which can limit the design options for your raked ceiling.
