Flashing Kings roof jacks are handmade from heavy-duty galvanized steel and finished with 100% soldered seams for ultimate durability and waterproofing. Used to prevent water from entering a home or building by protecting pipe penetrations through the roof deck. A roof jack, also commonly called a pipe boot flashing, receives and covers venting duct pipes from a variety of sources including: kitchen and bath fans, attic ventilation, or B-vent stack roof penetrations.
