ABSTRACT:
Light weight metal staging including a pair of roofer's platforms each about 4 feet in length with integral support means. On the ground, the platforms are telescoped together to make a short length, unitary pack for purposes of carrying up a ladder and depositing on a roof. On the roof, the platforms are manipulated so as to be set up in-line where one is the extension of the other to form the staging. The support means mount the staging on the roof. The overall length of the staging is about double the pack and provides a working length equivalent to that of the conventional 10 foot wood plank.
