This study aims to clarify the morphological representation of the sloping roof of contemporary architectures that were published in Japanese architectural magazine “A+U” that publishes articles on world architecture. The rooftop view and section figures were analyzed based on convexoconcave, straight or curved, breakpoints, and symmetry. Subsequently, the section figures were analyzed based on their deformation, the grounding angle, finishing material of their walls or roofs and the presence or absence of eaves. Consequently, 33 types of slant roof designs and 6 combination patterns in contemporary architectures were defined by the relationship of the roof surface figures.
