ABSTRACT:
A roof attachment apparatus for being mounted on a roof having at least one standing seam. The apparatus comprises a plurality of base plates for being disposed on opposite sides of the standing seam on a surface of the roof, a platform support member for supporting at least one scaffolding plank, and plural support bars. The support bars are orientated so as to enable a downward force applied to the platform support member (e.g., as a result of the weight of plank(s) and/or a worker) and transferred to the support bars to be directionally distributed to the first and second base plates in a manner which causes those base plates to displace towards one another and clamp the standing seam. In this manner, the apparatus is maintained in a stationary position for supporting scaffolding planks on the roof, regardless of the roof pitch.
