I HAVE ROSEMARY ROOF TILES LAID VERTICALLY TO THE FRONT OF MY HOUSE. ALL OF THE OTHER PROPERTIES TILES ARE EXACTLY THE SAME BUT THEY ARE DARK BROWN/BLACK BUT MINE ARE PINK/FADED RED I THINK THEY MUST HAVE BEEN PAINTED IS THERE ANY WAY I CAN REVERSE THIS OR DO I JUST HAVE TO REPLACE THEM MANY THANKS ...
