ABSTRACT:
The invention is a work table for use on a peaked roof comprising a horizontal frame forming the support surface, and four leg members. The leg members pivotally attach to the horizontal frame, and the angle of the leg members can be adjusted to correspond to the pitch of a roof. The table sits directly on top of a roof, with the sides of the legs directly against the roof, thereby holding it in place. The invention does not require spikes or nails to hold it in place, preventing damage to the roof. Additionally, the invention can be placed on the peak of a roof without anyone on the roof, ensuring the safety of roofing personnel.
