A roofer who is also a surveyor helping out on an unrelated, non-roofing job raised a number of issues with our roof, that was redone a few months back. The roof was done by a respected firm, and we paid a premium over other quotes because we hoped to avoid future work and problems. Hopefully they'll be open to addressing reasonable concerns but we're a bit unsure what we should be asking for. I'd really appreciate some other views on if these are all issues I should raise with the original roofers and what I should ask for as a remedy, or alternatively pay to have fixed myself while there's scaffold up.
The render has cracked so I'll be raising that at the least. Are any of these minor quibbles that aren't worth worrying about? Any views would be much appreciated, thanks.

According to the critical roofer:
The tiles (49s) haven’t been nailed. He says because we’re within 1.5 miles of the coast, British Standards say every other course should be nailed;
They’ve put timber in two places at the valley to support tiles. This shouldn’t have needed to be done. One of the tiles has already dropped. He was concerned the timber will rot and then more tiles will drop. The roofer who did the job says the batten tilt under the lower eaves is fully treated and won't rot;
The felt and breathable membrane extend over the gutter - he says the felt should have started higher up and will rot, and water will be soaked up under the roof. The roofers fitted felt, breathable membrane and TLX Gold insulation;
Some of the lead hasn't had patination, harming the lifespan. He said the horizontal lead has had patination but the vertical hasn't in the picture below;
Other concerns raised:
There should be lead straps securing the lead flashing.
There’s minimal headlap – he estimates 50mm, and you can see in many photos that previously there was more.
They should have used 38mm nails instead of 50mm, with the risk of piercing the insulation (which did happen). The roofer who did the job says that’s wrong and 50mm is the right size.
From inside the attic there are multiple examples of the nails coming through the insulation, eg:
The whole roof:
Thanks again to anyone who can share any advice or words of wisdom on any parts of this post.
