Discussion
Just had a few tiles similar to the pic flagged up on a survey for a house we are buying. What is the PH view on what could have caused this damage on a 5 year old house ? My view is it was probably when they were fitted, unless someone has been clambering over the roof, which we are assured they haven't.
Not Covid related, I think it’s connected with the way the tiles are extruded, cut to size and stored while curing that causes the bottom right to break. This is an American site I think tile problems that the discusses the issue.
The link in the article to the Roofconsult website went into great detail about the causes, which I read years ago as I wondered what the issue was. Sadly said link is no longer live.
Google ‘curved corner fractures’ for some bedtime reading.
The issue looks worse than it is and I wouldn’t loose any sleep over it

Probably been like since the day they were fitted. The Surveyor is just trying to find stuff as there won’t be much going on with a 5 year old house. I sold a 8 year old house recently, the buyers dad persuaded him to get a survey, the surveyor noticed 3 window keys were missing, they cost the poor lad about £150 each, cost me about £3.
Visually they look the same tiles as ours (although I suppose a lot look the same) - had an extension 4 years ago and whole house was re-roofed.
Loads had broken corners - a much bigger chuck than in that picture. The roofers were replacing most as they went along but there were about a dozen they missed and the builder did those before the scaffolding was taken down. They said it was happening as the tiles were very fresh.
Can't see how the main roof is now, but three have since cracked on the "lean to" extension roof that I can see from first floor windows. The broken pieces are still place - it's most noticeable they're cracked when they've got wet and are drying.
TBH I wouldn't be concerned about the small pieces missing off yours

I did think that, as it doesn't look like recent damage. The surveyor does seem a bit keen, even on the initial email report, so I dread to think what she will put on the full report.Sheepshanks said:

I'm not overly concerned. I just suspect it's one of those things that once it's been pointed out, I won't be able to stop looking at it Loads had broken corners - a much bigger chuck than in that picture.

We have a roofer (friend of a friend so hopefully ok) out looking at it today to see if it worth doing anything. wolfracesonic said:

Interesting article - it does mention the freshness of tiles that our builder pointed to. We did have un-level tiles at Velux window flashings too - the builder's joiner sorted that out.
Maybe the OP's picture is deceptive, or the tiles are a different size, but they look much more overlapped than ours are. We have noticeably more height visible than width. I presume more overlap would make missing corners less of an issue.

Ours are very similar - tiles are perhaps a bit more flush. I did query it but was assured that’s how they are, and the builder was pretty fussy with getting things right. Still seems a bit crap though.The overlap on each row of tiles looks much less from that picture than in it did in the first picture.
Our roofer has has a look today and the edges by the Velux window in the pic above are fine. The tiles (and a missing trim fixing) are all minor issues that are easily dealt with. He will have a look when he is up there to see if there is any obvious cause, other than the ones in the links in previous posts (I am a bit reluctant to tell him his job ). Scaffolding will be needed though, which I suspect will be more than the cost of replacing the tiles. Just waiting for the quote and then the difficult conversation with the seller !

Our conclusion was that they were s
