We've had our loft converted and have just received the request for the final payment. Because the chimney needed looking I had a local roofer come round to look at it. While he was here he noticed that the rubber sleeve on the weathering slate was very loose around the soil pipe coming out of the new loft bathroom whereas he said it should be a tight fit. I can see what he means - it looks as though they've just cut a large ragged hole. should it be a tight fit or is there any other way it can be 'used'?
