A roof truss is usually fabricated from wood during construction or renovation. There are many different types of roof trusses, and all of them support the other material that's used to construct the rest of the roof. They help support and spread out the load to the exterior walls.

Let's look at the different types of trusses that are in common use:
Bowstring Roof Trusses
Bowstring trusses are arched and usually large. They support the weight of buildings like aircraft hangars and warehouses which need plenty of open space within. Multiple beams make up an arch, with sheets of metal or other material making up the roof outside.
Water runs off easily from such roofs, and there is no need for a ridge cap like for other types of trusses.
Dual Pitched Trusses
The standard triangular truss design is such that two sides slope up to the apex above, with struts (called "upper chords") leading down from it. They are attached to a horizontal beam that makes up the base of the triangle.
The upper chords are typical of different lengths in this kind of truss, making the apex off-center. This allows plenty of open space unobstructed by poles for support.
It is an expert's choice to pick the best from the different types of roof trusses for a specific building and depending upon your unique needs and requirements.
