I've just fitted a fan Xpelair CF20T that I have to vent through the roof. I cannot find any websites explaining how to do this. I understand that I cut through the roof felt and tiles but how do you seal a cowl to the roof so it doesn't leak? Any help appreciated.

One of these should solve your problem, they are available from all roofing merchants and good builders merchants http://www.calderlead.co.uk/html/2614.html
Thanks for the responses. I need to get up on the roof and measure the tiles to select one of the tile vent products, it seems a good solution. I cannot vent through the eaves as I have concrete gutters round the house and would have to put in a ducting of 4-5 metres to reach the eaves. Nick
Again this is where Lapvent comes into its own - www.lapvent.co.uk - I have fitted loads and they do what they say on the tin (you may need a couple to assist flow though!).
nigel - thanks for questioning my logic, I phoned up Xpelair and the max length for ducting is 5m which allows me to reach the one place with an exit to the eaves! Saves a lot of work.
