Stage truss systems can span large distances and dissipate forces throughout the structure with load-bearing only at the ends. This can be very convenient in residential and commercial building construction because non-load-bearing walls can e placed at intervals between two ends of the truss system. This allows flexibility in spacing walls and allows for easy removal of them if necessary.
There are some disadvantages to truss system, which is why they are not used every roof structure. In situations where more room is needed in the roof area, such as attic rooms, stage roof systems might take up too much space.
