Shower roof vent problems

I have had a shower humidistat fan fitted in a new bathroom and the fan vent goes up through the ceiling and into the loft space via a white plastic flexi hose and then couples up to a roof vent. The problem i am potentially looking at is it may not have been correctly installed. The flex pipe is attached to the roof vent with brown packing tape, the underside of the roof has had a massive amount of moisture barrier cut away exposing a large area of roofing tile underside for just a six inch pipe, the actual zinc pipe flash has been mounted on top of a roof tile tucked inside the gap of the upper row of tiles above that locaton, the zinc square plate is not sealed to the roof and can very easily be lifted up to expose the gap going straight into the loft as there is no longer the membrane, the rubber boot that the zinc plate has bonded to it has been very roughly cut to accomodate the ducting pipe, the cut made on the rubber duct is not vey tight to the pipe and frankly looks like it was knawed by a rat. When inside the loft, daylight can be seen through the gap. I am quite worried that this job may not have been done right and that in itself may lead to other problems as the same chap has laid uninsulated water pipes very close to this area and the loft is not heated at all.

Can someone maybe advise me if any of this sounds right?, and if i should get a profesional roofer to have a look and give a quote to put it right, does anyone know anyone in the Pulborough/ West Sussex area who may be able to advise?.

Best regards.

With out pictures all I can suggest is to have someone "Roofer or Handyman"
who has experience with such work take a look at it.

It's sounds like the correct components (except I don't like the white vinyl duct, it won't last) possibly installed incorrectly. As Sly said, best to call a local tile roofing expert. Doesn't sound like a fix is terribly difficult or involved.

It sounds correct, but a picture would help.
