It would help to know what type of tile and the age of the roof (or

Here's a piccy I took last week of the hole

House is about 21 years old, I've lived here about 10.


Those tiles have to be nailed. So, no nail? Also, they have a lip that
hooks over the battens. Sometimes that lip gets knocked off but the
roofer still uses the tile. If a tile is slightly proud due to a bit of
mortar or whatever stuck under it, the wind will get in and lift it.
