leaky roof fix

I have a sloping tiled roof on a small extension on hte back of my house. Un fortunately it leaks in the corner. I have removes a small area of the board ceiling and can see that the felt under the tile is split and perished and when it rains the water comes through here. I have tried patching it from underneath but you cant press on it because it is unsupported from behind. I suppose I need to take the tiles off and fix ne felt over top but the tiles are mortared in along the edge.
Could somebody give me some advice on tackling this problem. Do I need to chip out this mortar to get tiles off? How do I patch the felt? Should the rain be coming under the tiles?

Bet you feel silly for not waiting the full 9 hours now eh?
The tiles should stop almost all the water coming in. Sometimes eddies in the wind over a roof will get it through though. You should have a lead or some sort of flashing set in the course of bricks above the roof to throw the water from the wall over the the top course of tiles on the extension.
I don't suppose this was omitted by any chance. (Oh yes I do!)
I think the tar paper, whilst initially a water barrier during construction, is there primarily as a windbreak. The reason it is in 1 metre aprons is to allow the roof to breathe, as it can condense a great deal of moisture from the house (not so much from the weather as warm air rising through an house pushes the colder back out the roof. And of course the warmer the air the more likely it is to be moist.)

I would advise you to get a roofer in Dan. If you have any doubts about your own ability to do the job, then you'd be struggling to tackle something like this on your own. Roofs can be dangerous to work on if they have any unseen rot in the timbers, especially where leaks are concerned, and would need to be checked by someone with the knowledge of what to look for.
This type of damage can occur through years of high winds and heavy rains getting under the tiles. If you think how many years it has lasted already, it gives some idea of how long it will last if repaired properly.
If you think you want to give it a bash, then have a look through these sites:

Good luck with it.
