Parts of a Roof Truss

The common roof truss is very easy to detect. There is a triangular shape and this forms the bulk of any roof truss for a modern home. Common trusses consist of seven main parts that are:

  • Web supports – These do the work of holding everything properly in place and at intermediary points.
  • King Post – The peak of the common roof truss needs to be supported and this work is done effectively by the King Post
  • Metal Gussets – These can be found used everywhere the web supports and the king posts intersect the top and the bottom chords and this can also be found near the bearing points
  • Tail – The tail of the common roof truss is used for making eave or an overhang and this gives the way for the attachment of the fascia and the soffit.
