Abstract
A flashing apron for use in grain bins roofs which has apron segments comprised of a single sheet of metal with a plurality of spaced crease lines therein wherein the crease lines create a plurality of truncated areas in an upper surface of the apron segment. Each apron segment has a side edge comprising a downwardly bent lip which fits underneath a side edge of an adjacent apron segment which is planar in shape and which lies on or above the bent lip. Suitable fasteners are provided to secure the apron segments together to create a composite flashing apron for mounting around the circular ring at the apex of the grain bin roof.
