Hi, I have an existing loft conversion with dormer and I'm looking to add a toilet/ ensuite to it. I need to run a soil pipe to the existing stack and the easiest way to do it is vertically out of the pitched roof. Is this possible with a rubber boot of some sort? I know the ideal would be to run the soil pipe under the floor boards and out through the soffit but it's much more work and there's limited space. Any thoughts appreciated. I won't do doing it btw - I have a roofer to do it and he's suggested the first solution as the best option.
