Roof trusses are wooden or metallic structures designed to provide support for roofs and bridge the space above a room occurring at different consistent intervals which are linked by longitudinal metals or timber like purlins. Trusses can be said to be the skeleton of a roof since they give it its shape and provide support to the roof. In residential roofs, trusses are composed of a series of triangular shaped sections and are pre-fabricated support members usually made using wood, joined with metals at every part where two pieces of wood meet.
