Our Copper Roof Vent Pipe vent Pipe Flashing Boots feature solid copper construction with a soldered in place zinc “bellows” that adjusts to fit the pitch of the roof. These roof vent pipe flashings are suitable for any slate (natural or synthetic), copper, asphalt shingle, clay tile, wood shake or composite shingle roof with a roof slope between 2/12 and 12/12. All units feature a copper base plate for flashing to your existing roof. Caps are included.

If your roof vent pipe is no larger than 2-3/4″, you can use the 3″ Vent Pipe Flashing. If your roof vent pipe is 3″ you must order the 4″ copper vent pipe flashing.
