Specifically, referring to fig. 4 and 5, the tile base has first and second

opposing sides

111c and 111d, and the substrate 111 has first and second

opposing surfaces

111a and 111b. When the substrate 111 is laid on a roof, the first surface 111a faces the roof. The lifting portion 112 is located on the second surface 111b, and the lifting portion 112 extends along a first direction D1, wherein the first direction D1 is directed from the first side 111c to the second side 111D.
