One of the benefits of a half hip roof is that it may accommodate a gutter that can be easily fixed all around the house.

You will layout the top of the unbacked hip rafter with these dimensions. To maintain a consistant ridge height in these situations the roof pitch must be adjusted. Hip rafter offset for hexagon and octagon roof framing drawing the hip rafter offset should be as easy as tying your shoe laces.
