Help! Roof tile identification

[Clairep33]

I have just moved into a new (old) house and there are some roof repairs needed. I have been searching the internet to try to identify the roof tiles but haven’t managed so far. Can anyone help identify them? They seem unusual as they have a sharp angle rather than a curve. They are over 40 years old. Any help would be greatly appreciated.

Thanks claire
