For any roof slope expressed as x in 12 rise in run the hip and valley factor is determined by finding the square root of rise run 2. When the building is square the hip roof is pointed at the top like a pyramid.

Divide the rise by the run the run is 12. It is so called because its shape resembles a butterfly s wings. It is as one of its names suggests a pitched roof but it generally cannot be seen from ground level as it is concealed behind a parapet wall.
