Truss roof construction is a type of roof framing technique that uses a truss to support the roof of a house or building. A roof truss is structural framework of wood or metal bars specifically designed to support structures, such as a roof or bridge.
The most common types of trusses are the pitched truss and the flat truss. The pitched truss has a triangular shape and is used for roofing support. The flat truss is used in floor building.
Roof trusses are commonly used in house or building construction because they can span large distances; therefore, it is possible to have larger rooms. Roof trusses can also take different shapes. A roof truss can have a tetrahedron, rectangular or triangular shape.
