I have put links for pictures below as this should explain it better.

Both these corners have what looks like a piece on concrete missing
which allows some drips to run down the corner of the house and stains
it red, how best to repair?

This one had fouled up gutters (now cleaned) and allowed water to
overflow and run down the building, at least thats what I think was
happening, I will be getting the slates on that side cleaned soon and
hopefully that will resolve the problem. Can anyone see any other issue
that may have caused the staining on that corner? The staining was
there when we moved in.

The staining looks like algae to me. Clean with pressure washer and
spray with bleach & then repaint..
It will likely come back, hard to get rid of.

It might be worth checking that there is not a common rafter there
covered with a thin layer of cement..
(There shouldn't be but there might be.)
If there is,it needs a verge/barge board to cover it, cement is no
good.

The fault is the fibre cement under cloak is short of the gutter and needs extending. The cement fillet has been pointed flush, this should be pointed back of the edge of the tile to form an overhang, this also stops the ingress of rainwater from entering behind the cement fillet pointing

Would this be an easy fix to extend the fibre cement, it has been like
this I assume since the ext was built late 80s (we only recently moved in)

kipper at sea..... All the surrounding houses are built the same with a
concrete edge so I would assume its ok, but will get my son to check it.

"The staining looks like algae to me" It does look like that as there
does appear to be a green tinge however from 50 yards back it is a
distinct reddish colour that matches the tiles and the guttering was
overflowing at that part before cleaning.

looking at the photos again, as the plastic fascia been put on on top of the originals. i can see that the tiles on the verge have verge clips, thats why the verge as been pointed flush, its an easyer way of pointing. one thing i cant see is this mould your on about, the only stain i can see is a black water stain on the tiles

After finding a photo #1 it looks as if you’ve had new fascia, sofits and guttering. As the wall under the verge strip as PVC barge fitted. This may help to prevent water stain algae, as the rain will now run onto the bargeboard instead of the stucco wall finish.

Yes I got the new stuff fitted earlier in the year, I wanted to get that
and a few other repairs done before I paint the outside.
