Hi

I've got a repair to do where an old wood stove flue used to go through the roof, but has since been taken down. Water had been leaking through and caused some rot to the rafter, which I will "sister" with some new timber.

What I don't know is whether it would be a good idea to repair/replace the sarking board, and the felt on top of it? If so, is it possible to do what needs doing from inside the room? Or is the only option to strip back slates and repair from above. Would prefer to do it from inside if at all possible.

Any opinions and suggestions on how best to approach this would be most appreciated.

Many thanks

Has it stopped leaking?
