(Optional) Prepare a roof plan.

Preparation should include choosing a proper scale and placing the following items on the drawing:

  • Edge of roof
  • All peaks and valleys
  • Exterior and bearing walls, shown as hidden lines
  • Protrusions through the roof (e.g., chimney)
  • Slope of each roof section
  • Location of gutters and downspouts
  • Notes and labels to include appropriate symbols 

Process/Skill Questions:

  • Why is it necessary to show the exterior walls on a roof plan?
  • Why is it necessary to show components that protrude through the roof?
  • How can a hip roof have two different slopes?
