The most common type of peaked roof truss is which?

• A. Kingpost truss
• B. Warren truss
• C. Triangular truss
• D. Pratt truss

Answer: (C)

Peaked roof trusses rely on triangles to stay rigid and transfer loads efficiently. The simplest and most common form is a triangular arrangement formed by the two sloping top chords meeting at the ridge and a bottom tie beam completing the triangle. This basic triangle is sturdy, uses fewest parts, and suits typical small-span roofs, which is why it’s the most widely seen type. The other names—king post, Pratt, and Warren—are variations that add members for longer spans or specific load conditions, but they all build on that same triangular idea. So, the triangular truss, as the standard, describes the common peaked-roof framing.
