Abstract
An improved flashing unit for use in weatherproofing a roof penetration including complimentary mating half portions of generally regid, high-strength sheet material, each half portion comprising a base plate, a generally semi-cylindrical stack portion attached to and extending upwardly from the base plate, each base plate having an upwardly directed generally semi-cylindrical flanged edge disposed within the lower end of each semi-cylindrical stack portion, a longitudinal edge portion of each stack portion forming an elongated continuous channel for receipt of a corresponding smooth longitudinal edge of the opposite stack portion for snap-fit frictional retention of the two stack portions when mated with the edge portions of the base plates in abutment, lap plates attached to abutting edge portions of the base plates to be received in lapping relation with an abutting side edge portion of the opposing base plate, and a generally cylindrical counterflashing, or cap, for surrounding a roof penetration and receiving the upper end portion of the mated stack portions in radially inwardly spaced relation therefrom. The flashing unit may also serve as a roof vent.
