In bungalow construction on a gable roof, what is the maximum on-center spacing mentioned?

• A. 12 inches on center
• B. 24 inches on center
• C. 48 inches on center
• D. 36 inches on center

Answer: (D)

On-center spacing is about how far apart the structural members are placed along their length and how much load each member has to carry. In bungalow construction with a gable roof, the reference material sets 36 inches on center as the maximum. That limit balances using fewer members with keeping the roof stiff enough and able to carry the typical loads (roofing, snow, wind) for a small, simple roof. Spacing tighter than 36 inches would be more conservative and use more lumber, while spacing wider than 36 inches would push too much load onto each member and risk sag or deflection. So, 36 inches on center is the practical upper limit for this scenario.
