Get a pipe flashing one size bigger than your pipe. Use a 3" pipe flashing for 2" or smaller pipe, use a 4" pipe flashing for 3" or smaller pipe, and use a 5" pipe flashing for 4" or smaller pipe!

Our German copper vent pipe roof flashings are made of 20-ounce copper, for 3", 4", or 5" pipes. The flashing covers your existing (plastic?) pipe and ties it into the roof in a water-tight manner.

If you need a permanent pipe flashing, this is it! These heavy-duty copper/lead, flexible, soldered pipe flashings are made in Germany to European standards. 

Applicable for roof slopes from 2:12 to 10:12 (bends to 12:12 if bottom of pipe is snipped off). Features a removable cap and flexible lead sleeve. Base plate is 12" wide and 15.43" high, hemmed on the sides to allow for copper extensions should they be needed.
