The main parts of a roof truss include the top chords (upper frame), bottom chord (lower horizontal part), webbing (internal supports connecting top and bottom chords), and king post or queen post (central vertical supports, depending on the style). These components work together to distribute the weight of the roof efficiently. Different types of trusses may have additional or slightly varied components, but these are the foundational parts found in most truss designs.
