Best way to get a vent pipe through a tiled roof?

[Ivor Windybottom]

I've got a couple of stinky stink pipes to get out of a roof that's going to be tiled with plain clay tiles. It's a fairly active vent from a home sewage treatment plant with an air pump, so it's a lot more active than the average sewer vent - it's constantly blowing out the air that gets pumped in. There are two of them - one from each end of the plant, both are 110mm standard drainage pipes.

I know there are invisible tile vents available, but I'd prefer to stick the pipe up through the roof so I can get it higher so less likely for the stink to gather around the building - I'd prefer smell-free to invisible.

I'm looking at those "weathering slate" things, I guess they'd do the job, but wondered if there are other options, perhaps less visible?

Also, two are needed - they'd be on the same horizontal course of tiles but I can adjust their spacing. Would it be better for them to be close with overlapping weathering slates, or separated with a few tiles between? I haven't seen such a thing as a double one, and I don't want to couple them to one pipe in case it limits the airflow.

Thanks.

If they are simply air vents, then why not combine them in the loft space and exit via one vent?

I was wondering about that, but it would halve the capacity, create back-pressure and possibly lead to unknown unintended consequences, e.g. the air from one going back down the other. One is rainwater, with an open end about 50m away, so potentially it could push poopy air that way if the wind blows the right way.

This bit of the roof isn't very prominent, so I'm not too bothered about how it looks.

Yours look OK. Are they lead or aluminium?

I'll space them so there is at least one tile width between them for them to run off onto.
