Roof repairs look dodgy

[nodogz]

We are having some work down on our roof. They are not finished and come recommended but I've kind of been shocked at how messy and noisy the work is. (And how hideous the clear up will be)

This is an angle I'm not happy with the finish on. There's so much concrete and I can see the lining in the join between the tiles. I don't know for sure if they are finished here yet or whether everything just needs some rain on it?

Is this normal? Or am I being paranoid because you don't usually scrutinise your roof too much? I wish we'd never started or moved out for a month

What did it look like before?
The exposed edge of the tiles facing you looks odd. Surely water will run right under them, unless they are putting something on them?
It is noisy and messy. We recently had a roof done and the noise and mess was horrendous. I can’t see ours, unless I stand across the road and look up, so I can’t say if yours looks odd or not apart from that end edge.
Why is it taking a month? Whole new roof on our detached house and garage has taken a week and that’s because the guy was on his own for 3 of the days. He did the neighbours house with two other men in 2 days.

The ridge tiles look like a wobbly line. We’re they like that before

They need to put flashing where the angle is - that is standard and they can't be done (but why don't you know if they are done or not)?
The lower part of the further roof - I think there should be some over hang (tiles not ending exactly where the wall ends) on the lower part, but it looks like they haven't finished, though I don't know what they would be attaching the tiles too.
They should be doing the clearing up.

Ridge tiles are straight and there is flashing in the join - it's hard to get the angle right in the photo.

It's taking ages because it's a big roof with little tiles and lots of angles. On a normal roof it might be 6-8 tiles per square metre on ours it's 60 tiles and we've picked slightly curved tiles to avoid a Lego roof look.

There's done more work to be finished off on another section so not sure if this part is finished as didn't ask when they left on Thursday.
