A protective waterproof cover assembly includes a a truncated-conical dome-shaped rigid cover adapted to overlie a fastener installed through a surface of a support structure and provide sufficient clearance between the cover and the surface to permit loosening of the fastener and movement of a head of the fastener away from the surface, a flexible waterproof circular pad having a diameter which is greater than that of the cover adapting the pad to overlie the cover such that an outer annular portion of the pad extends beyond a perimeter of the cover and overlies an annular portion of the surface of the support structure which surrounds the cover, and a layer of adhesive applied to a bottom face of the pad for adhering the pad to the cover and to the annular portion of the support structure surface. A peelable backing sheet is applied to the adhesive layer.
