Abstract
Abstract An anchor assembly for a flexible sheet of a roof covering, or a roof connecting strip, has a hollow section rail running along an upright wall section projecting upward from an edge of the roof, such as a parapet, at a location spaced upwardly from the roof. Such rail has a longitudinal slot bounded by upper and lower generally coplanar flanges and an upwardly projecting pocket-like extension which receives a thickened edge portion of the sheet. The sheet edge portion is thickened and forms a lip which bears against one of the flanges to anchor such edge portion.
