Lead slate for a low pitched roof

[jblack]

Hello All,

Our new extension has a 17.5˚ monopitch roof with Mini Stonewolds. We need to run a soil stack and a 68mm RWDP through it. The lowest pitch lead slate I can find is 35˚. Is it acceptable to use a flat roof slate or is there another solution?

Thanks, J

Use a multi-slate.

Cheers Noseall, is that the same as a flexi-slate?

It probably is yes. Lead outer. Rubber with cut-out inner.
