Generated explanation

The side-view illustration shows a porch roof supported by a column seated on a tall brick pillar beside the house wall. The junction between the dissimilar support materials is identified as a natural hinge point. The brick pillar leans outward relative to a dashed plumb line, while the upper column tilts at its connection to the pillar cap. Arrows indicate outward movement of the pillar and downward movement of the roof support. At the house wall, the porch roof and flashing are shown pulling away from the masonry.
