A hand tool has a plurality of similarly or identically shaped rollers aligned end-to-end along an axle such that the outer surface of each respective roller moves about an axis define by the axle. The hand tool may be a roofing roller tool that enables an impermeable vapor membrane or sheet to be applied to a vertical wall extending upwardly from an outer perimeter of a roof. The tool may be manipulated by an elongated pole handle coupled to a roller head or roller head frame.
