The plumbing stack on a slate roof should not be unattractive, not leave white lead streaks running down the roof, be completely maintenance free, last the lifetime of the slate, and NEVER LEAK. It should be made so that all future remodeling is simple.
A remodeling job a few years ago inspired this creative solution for plumbing vents and we are happy to help you as well if you ask. Our design requires more work up front, but then installs just like a piece of slate and requires no flashing. It is a maintenance free, lifetime solution that also looks attractive and blends in with the roof. It is now our standard practice in our slate roofing business.
Basically, the plumber has decided where vent stacks are placed. Well, that made sense 100 years ago when working with heavy cast iron pipes, but that should no longer be the case. PVC is used throughout buildings in all new construction and remodels. All cast iron will eventually be replaced. Of course, over the last hundred years the flashing failed, leaked or copper wraps create condensation between the old pipe and the copper (which drips into the attic). Anyway, there are many problems with the "current" methods of dealing with plumbing vents. So, our standard practice has evolved into cutting the stack in the attic and moving the vent to a desirable location. Scroll down below the pictures to continue reading.

We removed the two old leaking and ugly vent stacks and re-routed the vent pipes ... consolidating them into our new single plumbing vent stack installation.

First we intalled the new "slate" plumbing vent on the left, then we removed the old problematic cast iron vent stack and reconnected the plumbing vent in the attic to our new installation.
The photo (above) shows a vent stack in which we opted to keep a simple "sanded" stainless steel finish. There's another old stack (in the background near the chimey) that we'll do similarly when we reflash that chimney.
Fall Protection: We offer each client our V-18 or V-5 permanent roof anchor solutions. Here, the client opted for the V-1 temporary anchor solution. We'll remove the anchor and replace the slate once our front and rear slate repairs in this are complete. Most of our commercial clients and larger residences (understanding that roofs/buildings will always need maintenance) opt for the long term permanent anchor solution.

5 units were made to match the slate size and roof pitch for a historic library in Texas. The architect desired longevity, zero leaks, zero flashing headaches and a finish that would blend into the slate roof. Material choice: Stainless steel, fully welded, powder coated black, stainless steel screen, and bronze bolts so they won't seize if needing to be changed.
Plumbing Stack Rules:
Builders and remodelers sometimes ignore this rule, however, plumbing vent stacks should never be on the front of a home.
NEVER PERMIT PVC pipe penetrations through a slate roof. PVC through a slate roof looks terrible (even when painted) and a heavy snow load can break them.
Rubber/plastic flashing kits should never be permitted on slate roofs. Standard plumbing vent kits deteriorate in 7 years. The best ones last 30 years, but why use any of these on a slate roof ... which may have a life expectancy of 100 or 150 years?
Copper flashing that wraps around and over the vent stack often causes condensation (as warm vent gases come in contact with the copper in the Winter). The condensation forms between the plumbing stack and the sleeve and then drips into the attic.
Solder streaks and lead that turns white over time look lousy.
All cast iron will eventually rust through, even vertical stacks.
Plumbing code now allows for a single 2" pipe to vent the entire house. However, due to proper sloping of vent pipes, most homes will require at least two plumbing vents.
Never let a plumber work on a slate roof.

Two new vent stacks are shown in this photo, along with three of our V-5 permanent anchors. The two in background have their dark cast bronze cap covering them until their next use.
