Regular vs. Irregular Hip Roof
As an aid for calculating roofing materials (can be used in conjunction with the results of the
[Roof] function), the Hip/Valley Roof Area is included in BuildCalc's Hip/Valley function results.
For Irregular Hip/Valleys, the Total Hip/Valley Roof Area is sum of the
Major Area and Minor Area, as shown in above (the Major and Minor Areas
are the parts of the Hip/Valley framed with Jack Rafters).
Since Major and Minor Pitch is the same on a Regular Hip/Valley, only the Total Hip/Valley Roof Area result is shown.
