extractor fan pipe leaking , help

[assad khan]

Hi guys,

Our extractor fan has a leaking extractor pipe which has caused water to run down the walls when we switch the extractor on. When we had the kitchen built the builders place the extractor pipe so the expelled air goes through the roof , rather than having a independant point of allowing the air expel itself. can anyone help us?


We live in Luton , Bedfordshire

You need a roofer not a kitchen fitter, obviously the leak is with the roof and what ever flashing or decktite product the builder has used.
