An adjustable roof ventilator jack for operationally coupling a roof ventilator to a venting aperture extending through a sloped roof. The jack includes a base section having base section front, rear and side walls. The base section is configured so as to be angled in a direction opposite the slope of the roof. The jack also includes a pivotable section having pivotable section front and side walls. The pivotable section front wall is pivotally attached to the base section for pivotal movement between an extended configuration wherein the pivotable and base section front walls are in a substantially parallel relationship relative to each other and a retracted configuration wherein the inner surface of the pivotable and base section front walls form an obtuse angle. The jack further includes a position lock for selectively locking the base and pivotable sections in a predetermined angular relationship relative to each other.
