Which statement correctly defines a roof ridge?

• A. The vertical member at the corner
• B. The bottom beam supporting the floor
• C. A diagonal brace in the wall
• D. The horizontal member at the peak of the roof

Answer: (D)

The roof ridge is the topmost line where the two roof planes meet, running along the peak of the structure. It’s the highest horizontal edge of the roof and can be a ridge board (the alignment aid for rafters) or a ridge beam (which can carry load). This makes the description of it as a horizontal member at the peak exactly correct, since it marks the roof’s highest point and the join of the sloping sides. The other options don’t fit because they describe parts that aren’t at the roof’s peak: a vertical member at the corner is a post or corner stud, not the roof peak; the bottom beam supporting the floor is part of the floor framing; and a diagonal brace in the wall is for lateral stability, not the roof’s peak.
