The roof tile support system of claim 1, wherein the plurality of roof tiles float on the plurality of support elements, whereby each individual roof tile is supported against breakage by at least one support element.3. The roof tile support system of claim 1, wherein said roof tiles are arranged in courses and an upper course is supported by said support elements such that front portions of the roof tiles of the upper course contact back end portions of tiles in an adjacent lower course of roof tiles.4. The roof tile support system of claim 1, wherein at least one roof tile comprises a back end portion which overlaps a rear end of the support element on which it is supported.5. The roof tile support system of claim 4, wherein the back end portion of the said at least one roof tile is in contact with the roof surface.6. The roof tile support system of claim 1, wherein said roof tiles are arranged in courses and a first course is supported by said support elements such that front end portions of the roof tiles of the upper course overlap back end portions of tiles in an adjacent lower course of roof tiles.7. The roof tile support system of claim 6, wherein an amount by which the roof tiles in the upper course overlap the tiles in the adjacent lower course is configured to be adjustable during installation.8. The roof tile support system of claim 7, wherein said support elements have arch sections, and said roof tiles are barrel roof tiles.9. The roof tile support system of claim 7, wherein said support elements have a triangular cross-section.10. The roof tile support system of claim 7, wherein said support elements have a quadrilateral cross-section.11. The roof tile support system of claim 1, wherein said support elements are made of expanded polystyrene.12. The roof tile support system of claim 1, wherein said roof tiles are arranged in courses and an upper course is supported by said support elements such that front end portions of the roof tiles of the upper course are elevated some distance above rear end portions of tiles in an adjacent lower course of roof tiles.13. The roof tile support system of claim 1, wherein said roof tiles are supported by said support elements such that the weight of said tiles, or a concentrated load on said tiles, will be distributed over said support elements and said roofing surface.
