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:
- Top chord – The roof sheathing is plied to the top chord
- Bottom chord – The drywall or the finished ceiling is attached to this part of the roof truss in modern homes
- Bearing points – The common roof truss is designed to sit on the outside bearing walls of the houses
- 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.
Types of Roof Trusses
- Raised Heel trusses – These are taller at the bearing point. This allows for insulation to be added at the exterior edge of the building
- Scissor Trusses – Used to make a cathedral ceiling
- Hip Trusses – Hip roof framing and are used in three modes – Terminal, hip master, step down and Dutch hip truss system
- Mono trusses – These are a half of the common truss and are usually kept at a ninety degree angle to the girder truss.
- Room in attic trusses – These come in the bottom chord used as the floor joist and the support webs designed for the purposes of wall framing.
