There are several advantages for builders using trusses instead of stick framing:

- Designed and developed by engineers, roof trusses are constructed to meet all roof load and building requirements
- Overall construction time is significantly reduced as roof trusses are prefabricated
- Roof trusses are mostly built using two by four stock, which significantly reduces costs when compared to the longer framing pieces used in traditional stick roof framing
- Easy to install, today’s roof trusses can be installed by less experienced builders, saving on costs.

Kingpost Truss – suitable for spans up to 4.5 metres and used primarily in house and garage constructions

Queenpost Truss – spans up to six metres and mainly used for domestic structures

Fink Truss – spans up to 11 metres and the most commonly used domestic truss. The shape allows a water tank to be accommodated

Fan Truss – spans up to 16 metres and used mostly in large domestic dwellings and commercial buildings

Double W Truss – spans up to 16 metres. Popular in both commercial and domestic builds

Raised Tie Truss – applied to internal web structures to add extra headroom or provide an attractive architectural feature

Room in Roof (Attic) Truss – provides a structural roof and floor in one complete section and allows for additional space in the roof

Scissor Truss – features a sloping bottom chord to provide additional headroom and has a 15 degree difference between the top and bottom pitch

Modified Scissor Truss – shares the same detail as the Scissor Truss but with a flat section to it’s ceiling

Mono Truss – generally used for lean-to and hipped-end roofs. It can also be spanned onto fire walls or used back-to-back onto central corridor walls

Hip Truss – used in hipped roof construction. It can also be used for roofs which require a reduction in height for planning requirements

Lattice Truss – used in many situations including infilling large attic sections around dormers and stairs and for flat roofs.
