    • Improved roofworker support apparatus (10) for placement on slanted roof structures (112) with varying peak angles, and including a pair of peak-adjustable elongate assemblies (20) independently deployable on the roof structure in spaced substantially parallel positions extending up the roof, each including at least one elongate crosspiece removably supportable across the elongate assemblies (20). The elongate assemblies (20) include an elongate roof-contact member (22), and overpeak member (24), an adjustment member between the overpeak member (24) and the roof-contact member (22) and adjustable to set the elongate roof-contact member (22) and overpeak member (24) at desired angle to accommodate roof peak angles, and at least one crosspiece-support member (50) affixed to the elongate roof-contact member (22). Highly preferred embodiments include certain extension members (70).
