First thing to do is give it a good clean.
Give the trough a go with some paint on liquid rubber roof sealant.
Next replace the gutter on the roof with a wider set-up so that it's less likely to overflow.

If the gutter overhangs your roof. Either your garage is trespassing or their gutter is trespassing. Are you both built up to the boundary?

Yes gutter on my side so I could remove it he has it connected all round to other side of his garage .

Really their roof needs a parapet gutter.

Well I guess the water would run on my roof if it was not there I guess I need to build a slope .

That is a really poorly thought out location for a gutter. Probably a hangover for when the garages were one big flat roof (?).

Ideally, it would pitch to the rear (or where the gully is located), where you'd have an accessible, serviceable gutter.

Yes his gutter made it a pain

It's unfortunate, but I guess your neighbour saw and alleviated the problem first. It was never a good Idea to begin with.

Yes I know can remove it and put it back I just need to find best solution to create a slop so water will run .
