A spacer is provided for use in a standing seam roof system in which roof panels are provided having a base portion and upstanding side flanges along opposed longitudinal sides of the panel. The panels are installed sequentially along roof purlins in a working direction. Occasionally a portion of each panel being installed trails in the working direction in relation to the remainder of the panel. A spacer element is provided with a hook for being suspended in the seam between upstanding side flanges of adjacent panels to advance the trailing portion of the panels and thereby straighten the panels of the roof system. |
