Is it worthwhile having my 90 year old roof cleaned?

Several months in and I’m trying to prioritise works on my house having done sweet F.A. so far.

The survey picked up some growth and re-pointing necessary to the (disused) chimney stack and nesting jackdaws.

There’s a lot of moss up there. The roof is original. The house would be a good candidate for a loft conversion but this isn’t something I’m likely to do as I don’t need the space. Equally there are no problems with the roof. As you can see my neighbours have had theirs re-tiled at some point.

I'm not looking for jobs for the fun of it, but if having it cleaned / touched up is the difference between the roof lasting the duration of my ownership and not...

Next owner will likely want to convert the loft...

The roof will be ok , moss doesn’t hurt it , but I would get the chimney tidied up , raked out and re pointed and the top re set .
It’s obviously very damp as there’s a small garden growing.
