A truss base is a closed polyline that defines the area in which valley fill roof trusses are to be built across and above the tops of normal full size roof trusses.
In a standard gable roof the ridge board does not provide structural support for the roof and is used primarily as a nailing surface for the upper ends of the rafters.
The role of the horizontal beam is to tie the truss together and carry the load that would otherwise be sustained by the support and vertical timber also known as the king post.
Attic conversions are now possible by replacing the truss rafters with a shaped trusses or horizontal beams which in return create additional space.
