If debris builds up against the nail style clips that secure your tiles it can cause water spots on your ceiling.
A build up of dirt where the tiles overlap can also cause water entry by capillary action over the head of the tiles.
When the tiles are removed you can see white water spots on your ceiling. These photos are taken from the roof looking down on your ceiling.
The constant water drips cause mould spots to appear on your ceiling. Eventually the constant dripping will make hole through the ceiling plaster.
The solution is to clean the debris from the water course of the tile.
We relay the tiles using a wire spring clip that is less likely to cause the same problem.
