Hi all
we are having a loft converted currently and have a bathroom in the dormer area. The builders have put in a 100mm hole up through the ceiling , waiting for the ceiling extractor fan to go in. But i`m querying to them where the ducting is as cant see anything apart from obs board above. There doesnt seem to be any extractor vent on the outside, so i assume if it is there, its going into the soffit. I`ve checked back on some photos of the build and i couldnt see any allowances in the joists of the roof for a 100mm ducting pipe. The builder said the ducting is up there so i`m taking his word for it.
Question is, I need to check properly to see whats up in the ceiling. But could at worst the vent go straight up onto the flat roof , obviously its better to go out the side and avoid having to put a flat roof vent in. But surely you cant put a 100mm hole through a joist. There must be two at least as the extractor is in the middle of the bathroom ceiling.
Trying not to cause hassle with them as they are nearly finished and done a good job but i`m just suspicious.
Thanks
