We have concrete double pantiles on our roof which are embossed on the back Camtiles 888515 and are trying to identify the colour and how much they cost. We have tried looking on various reclamation yard websites without success. Attached are a couple of pics which show one of the tiles which has not been on the roof and was laying around behind the shed. We need to decide whether it is best to reroof or add to what is already there.
