A ROOF TILE (20) IS PROVIDED WITH A GROOVED RAIL (26) AND LOCKING GROOVE (32) SO THAT EACH ROOF TILE (20) CAN BE LOCKED TO THE OTHERS AND IS MOVABLE TO ADJUST THE SPACE 5 BETWEEN ONE ANOTHER, AND THE SLIDING OR OVERLAPPING DISTANCE CAN BE ADJUSTED. THE PROVIDED GROOVED RAIL (26) AND LOCKING GROOVE (32) SERVE AS A STRUCTURE TO RECEIVE WATER FALLING AGAINST THE ROOF IN ORDER TO EFFECTIVELY PREVENT A BACK FLOW OF WATER TO THE INSIDE OF THE ROOF AS A RESULT, THE APPLICATION OF ROOF TILES (20) ACCORDING TO THE PRESENT INVENTION ELIMINATES THE NEED TO USE THE SUB-ROOF BOARDS AND FELT PAPERS, THUS REDUCING IO THE COST FOR THE TILES AND INCREASING COST-EFFECTIVENESS. IN ADDITION, IN COMPARISON WITH COMMON NATURAL WOOD ROOF TILES IN THE MARKETPLACE, THE PRESENT INVENTION REDUCES THE UNNECESSARY OVERLAPPING SPACE BETWEEN DIFFERENT LAYERS OF THE ROOF TILES (20).
