Hips & Valleys
• You already know hips bisect the angle of an external corner
• A Valley is formed in a pitched roof wherever an internal angle / corner is found on the roof plan
• The main roof is referred to as the “major roof” and has the major span
• What's known as the offset is the “minor roof” and has the minor span
• The offset is important, see next slide

Offset
Will create the gathering point for the valley – centre to centre of gathering points
These two distances are equal

• Valley Rafter P 31 – The valley runs from the internal corner to the minor ridge and forms the junction of the sloping roof members. On plan it will bisect the internal corner and has a plumb & edge bevel which are the same as the plumb and edge bevel hip rafter

• Valley Creepers P 33– These are rafters running from a ridge to the valley rafter and have the same bevels as the other creepers and provided the spacing remains constant, the same difference in length.

New Members continued
• Broken Hip Rafter P 74 – This rafter joins the main ridge to the minor ridge and is part of a full hip rafter that would form the corner of the main roof before the offset was added

New Members continued
• Cripple Rafter or Crippled Creeper P 81– This runs from the broken hip to the valley rafter, isolating the offset and valley, it is a single line development of that portion of the roof.
