Question: A shed roof has a total span of 4.8 metres. The required headroom dictates a pitch of 4:12 with an overhang of 450 mm. What is the total rise of the roof from the lower wall plate to the top of the upper wall plate, ignoring the thickness of the roof framing members?

Answer options:

  • 1920 mm
  • 2200 mm

Correct answer: 1600 mm

Explanation: A 4:12 pitch means for every 12 units of run, there are 4 units of rise. The total run is 4.8 m = 4800 mm. So, the rise = (4/12) * 4800 mm = 1600 mm. The overhang doesn't affect the rise over the span.
