Roof Trusses: Sunshine Coast and Surrounding Areas

We use the best quality hardwood or softwood timber to manufacture our timber wall frames and timber roof truss structures. Therefore, we must use local species of wood that are strong, stiff, and dense and can hold nails and other fasteners.

The engineering and manufacturing of timber roof trusses are carried out to exacting standards, requiring special handling, erecting and bracing techniques. Generally, the maximum span of truss-supported residential buildings (National Construction Code (NCC) Building Classes 1, 2, 3 and 10) and light commercial buildings is 16 metres, and the maximum roof pitch is 45 degrees.

Most basic timber roof trusses have timber dimensions of 90x35mm and start with a strength grade of MGP10, which complies with Australian Standards. MGP is a term used to describe machine-graded pine lumber.

The more stress the pine can handle, the larger its MGP rating will be. Therefore, if the truss requires a larger timber size due to how much load it will carry, it is generally applied to the bottom chord first, leaving the top chord and webs at 90x35mm.

There is a risk of falling through roof framing when no appropriate control measures are in place to prevent workers from falling. The injuries a worker can sustain from these falls can severely impact their ability to continue working. There have been fatalities in some situations.

Because of the hazardous nature of this type of work, there are specific provisions within the Work Health and Safety Regulation 2008 (the Regulation) that apply to employers when this type of work is performed. This is why it is always important to enlist the services of trained professionals rather than attempting this work yourself.

There is a standard spacing between trusses, typically 600 mm, 900 mm or 1,200 mm, depending on the structure’s purpose. Depending on the type of material used for the roofing and local practice, the spacing may vary. It is possible to configure a range of truss types to achieve a variety of shapes.

The overall cost will include a range of factors, including council fees and permits, the size of the building, the type and size of the project, labour costs, the choice of material and more.

Truss designs and construction will be less costly when timber is used as the preferred material. For example, if you decide to use timber for the structure of your house, then you can expect to save approximately 10-20 per cent on the cost for your home compared to steel trusses. This is a significant saving when you’re working with a limited budget while still getting a quality product.
