Roof trusses use materials that have been manufactured to create shapes or jigs, which can be attached together in varying designs by contractors. Roof trusses support the weight of roofs. Roof trusses are typically made from timber. There are a number of types of trusses that can be used, depending on the type and size of the roof that your property has.  


Timber roof trusses are typically strong enough to span a large area without requiring internal supports. This means that fewer materials are required which reduces cost. Additionally, timber trusses can be used for a range of different types of roofs, which makes them versatile. This is because they can be easily manufactured and fitted in different structures. Furthermore, timber is highly recyclable so any waste from making timber trusses can be used again.


Trusses can be made to fit around features such as hot water systems, air conditioning units and skylights. Your truss will be custom built so that it is suitable for the shape and size of your property. Roof trusses are generally either flat or pitched shape. Triangular shapes are the most commonly used. This is because a triangular shape is a strong structure to support the weight of the roof. 

This will consist of a number of triangle pieces which are fitted to the size, design and pitch of the roof. Within the flat and pitched shape categories, there are further types of trusses. This includes king post trusses, queen-post trusses, fink trusses, double pitch profile trusses, mono pitch trusses and vaulted trusses.

Types of roof trusses

King post trusses are generally used for smaller roofs in buildings such as garages, outbuildings and extensions. However, they can also be used for larger roofs. Queen post trusses feature a vertical piece of timber which is supported by triangle structures on either side. Fink trusses are now typically used instead of queen-post trusses. A fink truss features a shape which is fitted between a timber frame. This simple design can be used effectively in many buildings.

Double pitch profile trusses are used to produce varying roof pitches. They are generally used in commercial properties. Mono pitch trusses can be used to support leaning roofs or roofs which feature one pitch. They use timber that is positioned at a right angle and a rafter.

Scissor or vaulted trusses can be used for arched ceilings or to produce varied ceiling designs. Raised tie trusses are used to form arched ceilings. For more information, contact a company like Prefab Technology Pty Ltd today.
