A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof.
Trusses usually occur at regular intervals, linked by longitudinal timbers such as purlins.
The space between each truss is known as a bay.

What are the 3 types of trusses?
Simple truss – indicates a single triangular truss. These trusses are most often used as the roof trusses.
Planar truss – as the name implies it is a two dimensional truss.
Space frame truss – Contrast to planar truss, the members and the nodes are located in the three dimensional space.
How long does it take to install roof trusses?
In most cases, manufactured roof trusses can be installed within just one day. However, if you’re new to the process, it may be a bit of a learning curve.
What is the difference between a roof truss and a roof rafter?
Rafters contain two main outer beams which support the roof structure.
On the other hand, trusses come with multiple beams which add more support.
Moreover, as said earlier, the entire weight of the roof is equally shared by a series of triangles inside the main frame.
How far can you span roof trusses?
A roof truss can span up to 80′ without support, however in any home that distance would be impractical and incredibly costly.
Trusses are designed to span spaces without interior supports, and spans of up to 40′ are the most common in today’s homes.
What is the strongest roof truss?
There is no “strongest” truss, but rather, one that is most appropriate for a specific application.
There are four basic types of truss design: dropped chord, raised chord, parallel chord and scissors.
Dropped chord uses a beam on two load-bearing walls and can restrict interior space.
How do you brace roof trusses?
Temporarily brace the first truss back to the ground, plumb, straight and in the correct position.
Brace each successive truss back to the first truss with TrussSpacers.
Alternatively, use a gauging rod to accurately space them and install continuous temporary ties to secure the trusses.
