摘要

The roofing has a roofing panel (1) in plane tile form, where conical projections (4) e.g. turbulators, with upper surfaces (5) protrude from an upper side (2) of the roofing panel and lie in a common virtual plane. The virtual plane has a determinable inclination angle between a ridge and an eave, and is eroded at the lower side by external air. The projections are formed of ribs, and the roofing panel is formed from concrete, metal or plastic.
