The invention relates to a roof tile, which is intended for covering a roof by combining several roof tiles (10). The various layers of the roof tile (10) include a support layer (14) and an insulating layer (15, 16) on both sides of it. In addition, there is a surface layer (17) on the opposite surface of the first insulating layer (15) to the support layer (14) and a protective layer (18) on the opposite surface of the second insulating layer (16) to the support layer (14). The protective layer (18) is formed of a film (20) arranged permanently in the roof tile (10), which covers entirely the opposite surface of the second insulating layer (16) to the support layer (14). The invention also relates to a method for manufacturing a roof tile.
