Ceramic roof tiles have a life span over 30 years. However, design may change.
If you have to change only a few tiles, we recommend:
Go to a store of materials and check if a current model can match your old tile.
You will easily identify the manufacturer and model of your roof tile as per the marks and codes in the back side of the tile.
If there is no chance of matching your roof tile with a new model, we recommend you remove the tiles to rebuild a full slope.
Keep the remaining tiles for further possible repairs.
