A building panel having inner and outer faces on a body outlined by opposite ends and by upper and lower edges with opposite ends of the panel adapted to closely face the end of an adjacent panel in the same course or row. The outer face of the panel includes a lower portion of substantially larger surface area adapted for weather exposure and an upper portion of relatively smaller surface area adapted to underlie a lower portion of the back face of one or more panels positioned in a next higher course. A flashing element is mounted on the outer face of the panel for precise pivotal movement between a first position wherein the element lies entirely within the outline of the panel body and a second position wherein the element extends outwardly beyond the body of the panel for flashing a joint between adjacent panels. |
