A pitch pocket assembly for sealing an aperture in a roof includes a first member and a plurality of flashing members. The first member includes a wall portion and a plurality of flashing portions. The plurality of flashing portions extend from and are substantially perpendicular to the wall portion proximate at least one deformation zone. The plurality of flashing members are each attached to the first member. Each of the flashing members at least partially overlaps at least one of the flashing portions. The wall portion of the first member is bendable along each of the deformation zones to form a pitch pocket having the flashing members at least partially overlapping the flashing portions of the first member.
