Hi Clive- each property is different. Tile vents of course do create further air flow through the roof space. Unless you have any problems with damp or mould Then it should be fine as there is more than likely a few other ways of air to get in and out. If it really does worry you then of course place the job on the website and get some quotes and carry out the work- shouldn't be anymore than £140.00 Lew.
