Whilst in my loft last weekend, I discovered that the pipe from the extractor fan in the bathroom is merely sitting on top of the inside of the soffit. Although there are slits in the soffit, there is no proper vent for this pipe. The house is only 5 years old and we bought it last year. Should the builders have fitted a proper vent? The condensation and mould on the inside of the roof is really quite bad above where this pipe is sitting on the soffit. The pipe itself is a 4 inch grey plastic one with a white flexible plastic attachment.
