At the beginning of a building project, construction professionals must decide whether to utilize timber trusses or opt for another roofing material such as steel. Trusses are the triangular units used to stabilize and support the roof of a property, helping to distribute weight away from exterior walls. If you’re a homeowner or builder wondering whether timber trusses are suitable for your project, we’ve collected a handy list of pros and cons to help you make a decision.

What are the pros of timber roof trusses?

Timber roof trusses come with a vast array of advantages, including:

1. They’re versatile

You can use timber roof trusses with various construction materials such as steel beams and components made from metal and wood. What’s more, timber trusses use less wood than traditional pitched roof designs and can span greater distances. This is good news if you’re hoping to create a large, airy space while maintaining impeccable structural integrity.

2. They’re cost-effective

For the most part, the installation of timber roof trusses does not involve using heavy machinery, as trusses are light and easy to lift. As such, they represent a cost-effective solution, eliminating the need for expensive machinery hire while shortening the life cycle of a project. Timber trusses also reduce the cost of site clearing as they do not produce excessive amounts of waste.

3. They’re eco-friendly

Timber captures carbon while releasing oxygen, thereby helping to combat the build-up of CO2 in the atmosphere. If that weren’t enough, timber production consumes less energy than that of many other construction materials and is entirely renewable.

4. They’re very strong and durable

Timber trusses are very strong, ensuring that buildings are safe and destined to last. They are so robust that timber trusses are suitable for scaffolding, concrete formwork, and falsework for industrial projects.

5. They’re aesthetically pleasing

There’s no denying that timber trusses look great in contemporary and period properties alike. The timeless aesthetic of wooden structures also offers architects and construction professionals broad scope for experimentation. Timber trusses are perfect if you want to build something pared-back and airy, for example.

6. They can help property owners save energy

Thanks to their insulating properties, timber trusses help property owners reduce their energy consumption, thereby saving money and protecting the environment. Indeed, timber is much more energy-efficient than materials such as steel and can be used to construct insulating cavities in the roof of a building.

What are the cons of timber roof trusses?

Timber roof trusses aren’t associated with many disadvantages. However, it is worth noting the following potential cons:

1. Timber can warp

In certain conditions, timber can change shape and slowly contribute to building damage. To prevent compromising the structural integrity, builders must consider how to protect it from the elements.

2. Timber invites pests

In certain localities, pests such as termites can present a risk to timber structures. Severe infestations often lead to hollowed-out structures that present risks to occupants. Some local authorities in certain Australian regions advise that property owners book regular pest inspections to avoid this.

Are steel trusses cheaper than wood?

Steel roof trusses are usually more expensive than wooden trusses, but they do last a lot longer than timber and require very little maintenance.

buildsteel.org - Timber or Steel Roof Trusses? - BuildSteel.org

As roof trusses replace rafters as the standard choice for roof support in most multi-family residential buildings, Architecture & Design completed a quick overview of timber versus steel roof trusses. Roof trusses are incredibly strong and quick to install, and effectively transfer all the weight to the building’s exterior walls, relieving the load from the interior walls. It’s important to select the right roof truss solution for any building project – residential or commercial.

Timber trusses

Generally cheaper than steel trusses, wooden trusses don’t last as long because timber, being a natural material, cannot stand up to the elements as well as steel. Timber trusses are exposed to warping and bowing problems, which can cause structural damage to the rest of the building. Wood is also susceptible to rot and insect infestations, which may call for costly repairs. Timber trusses are more likely than steel to get damaged in extreme weather conditions. However, despite these risks and the possible ongoing cost of repairs and maintenance, timber frames continue to be installed in constructions because they are considered more economical.

Steel trusses

Steel roof trusses are usually more expensive than wooden trusses, but they do last a lot longer than timber and require very little maintenance. Steel trusses deliver multiple benefits to construction projects: For instance, they don’t need chemical treatments to maintain the frame; are not subject to insect infestations; and are lightweight, allowing easy and quick installation on site. Steel frames can also be recycled easily, making this option an ideal one for the environmentally conscious home or business owner. Although steel frame roof trusses require more skill to install, an experienced team should be able to fit them quickly and efficiently.
