Different Types Of Roof Trusses And Their Uses
Building a roof can take weeks—sometimes months. Speed up the process (without sacrificing structural integrity) by installing roof trusses.
Roof trusses are a structural framework that supports the roof and connects it to your home. This modern type of roof structure is stronger and more affordable than roof rafters. Unlike rafters, roof trusses come in prefabricated packages, meaning you don’t need to build them from scratch on-site. This leads to quicker installation.
Once you decide to use a roof truss, the next step is choosing which type to use. Not all roof trusses will be the best fit for your building structure.
Are you fixing a damaged roof, or building a new one? If so, you’re probably wondering which type of roof truss will work best for your project. We’re going to cover the different types, and why you might choose one over another:
Types of Trusses
The structure of a roof truss resembles a triangle. Within that triangle, there are straight beams that each bear the weight of the roof. The result is a web of wooden or steel support pieces, all working to evenly distribute weight and reinforce the building’s structure.
Roof trusses vary in their structure, materials, and span. To see an illustration of the different shapes of roof trusses, check out this resource. Below, we’ve explained the most common roof truss types:
Fink Truss
This is by far one of the most common roof trusses, especially for residential homes. A fink truss offers a great strength to material ratio due to its W-shaped structure. Alternatively, you can try a Double Fink Roof Truss for additional support.
Queen Post Truss
This roof truss type is suitable for spans around 10m. It features a simple and widely applicable design that makes it fitting for a variety of building types. For spans that are on the smaller side, you can choose a King Post Truss.
Howe Truss
When you need a roof truss with a wide span (up to 30m), consider a Howe Truss. It’s typically constructed of wood, with a few pieces of steel for additional reinforcement.
Scissor Roof Truss
The main downside of a scissor roof truss is that the vaulted ceiling leaves little room for insulation; as such, it won’t be the most energy-efficient roof. But if you want to use the attic as extra living space (a spare bedroom, home office, or games room), this makes for a solid pick. This truss features a sloped ceiling for extra strength.
Raised Tie Truss
Want to pack your roof full of insulation? The Raised Tie Truss is a solid choice. This roof truss costs more than other types listed here, but it also lowers your energy bill—pay more upfront to save more in the long run. If you want extra headroom in your attic, this might be the roof truss for you.
North Light Roof Truss
Here’s another option for roofs with a large span (20-30m). Due to its wide design, this roof truss allows for adequate ventilation. It’s also highly durable and resistant to wear and tear.
