Finding and fixing a conservatory roof leak

[DIYNovice1979]

Hi,
I recently noticed that the ceiling of my conservatory has wet plaster in a section and the paint is starting to flake off. The conservatory has a tiled roof, I've been outside, there's no obvious holes or gaps, however it looks like some of the sealant in one section has worn away, but it hasn't worn away above where the damp spot is.

How do I find out what's causing the leak/damp? When I get a sunny day, I'm planning on climbing on to the roof to repair the sealant, is there a special type of sealant I should be using for this roof?

The leak is located under the right side of the window as you look at the second/middle picture (however I've found no signs of wear or gaps directly above on the roof).

I've attached a few pictures and highlighted the damp spot and where the sealant looks like it's breaking.
Thanks

Forget the sealant..more likely to be a blocked channel.

Sealant?

Roof windows are reliant on clever flashing design and competent installation.

Pull the ridge tiles and slates off above the window, clean up that mess of sealant and do not reinstall, if the flashing is well installed cut the slates a little shorter on the bottom row to give you a chance at being able to clear it. I think I'd also do the same on the sides so you've got an inch or so down the sides to be able to clear too, but have. A look down under the side slates when you get the top ones off and see if the flashing channels are clear

Thanks Robin,

Another question, I'm 11st, do you think the roof will take my weight without any issues?

Yes

A glass roof conservatory can take a persons weight, so yes it will
