Slate roof repair

I'm looking at an old and somewhat rundown house with a slate roof. there is a pretty significant bit of damage to the gable end. I think it looks there was some tree damage that went un-checked and has allowed the timber to rot. The rest of the roof looks ok to my untrained eye, although there is some other plant damage and the odd tile a bit loose or missing a corner. How hard is this repair likely to be? Will a lot of slates need to come off, I know with a clay tile roof you can pry up a local area but can this be done with slate?

Any opinions on the rest of the roof would be appreciated, whatever they may be.

Hmmm, seems OK for me, even in a different browser and not logged in. Can anyone else see/not see them?

Well it's a nice slate.
Roof condition , the obvious verge damage and various split and slipped and slipping slates . I suspect nail fatigue.

As it stands it is not too difficult a repair and you would start by stripping back more of the verge in order to reinstate the fascia and possibly the last rafter if that has suffered too. The lats would then need replacing and staggered so they are not all cut onto the same rafter. It is then easy enough to slate in as normal working your way up the verge to the last slate which can be fixed with a roofers adhesive or strapped with a tingle.
To do the job properly though you would need a strip and recover as there looks to be no underfelt or membrane and there is most likey no insulation either so a few points to consider for you but it looks like a nice spot to be.
