ABSTRACT:
Roofer's staging having a pair of light weight, metal platforms telescoped together and longitudinally slidable between closed and open positions. In the closed position, the platforms form a short pack (about 4 feet in length) for a roofer to carry up the ladder and deposit on the roof. On the roof the pack can be expanded so that the plaforms extend in-line to form a staging (about 8 feet in length). A major feature is that the roofer has the option of expanding either to the right or to the left.
