Underneath a roof tile, you typically find roofing felt or underlayment. This material serves as a moisture barrier to protect the roofing structure from water damage. In addition, there may be roof sheathing, usually made from plywood or OSB (oriented strand board), which provides a firm base for attaching the tiles. The combination of these layers ensures durability and weather resistance for the roof.
