If a tile appears to be mildly damaged, it could be possible to repair the tile. A layer of roof sealing material has to be applied to the crack. The material will be able to flow through the crack. Once it has become solid, the crack becomes closed.
You would want to replace the tile in case the crack is somewhat larger, or if it is broken. You would require to insert a flat bar below the tile and gently pry the tile up.
In case it is too tight, you may want to hammer it carefully such that it either loosens or breaks – such that you can remove it easily and without breaking the surrounding tiles. Then you would have to insert the new tile.
There are a few points you may want to make a note of.
You may not find a tile perfectly matching the color of the other tiles. Do not postpone your repair work – the damage to your roof would further increase.
Be careful while walking on your tile roof to the broken tile – such roofs are often slippery and may be risky if you don't have prior experience.
