Replacement roof and soil pipe

[kazgaz]

Hi guys

We're getting a replacement roof in the next few weeks. I replaced the external soil stack for new PVC around 5 years ago and this vents through the roof. (See pic)

Would this be a good opportunity to reroute the soil stack with an offset around the new gutters and soffits I'm also getting fitted? It'll save cutting holes in the soffits and roof, making the roof even more watertight?

Thanks in advance.

Yeah i would- any penetration through a roof is a potential leak.

This is what I was thinking. Thanks oldbutnotdead.

Best to use solvent weld for the offset- the rubber seal types might go a bit wonky in high winds

You could cut it lower and use a Durgo valve which lets it vent but without the odour.

I read about these but thought these are for internal use only? It would look a lot better tbh. Cheers DAZB.
