Abstract: A fastening system for a plate-shaped structural element on a pitched roof is provided. The plate-shaped structural element is bordered in a water-tight manner in a frame and fully replaces the roof covering, and the eaves-side and ridge-side cross beams of the frame which run transversely to the ridge-eaves direction have profiles which are matched to each other and engage in each other. The top side of the eaves-side cross beam has a mounting that surrounds the edge of the plate-shaped structural element, and the bottom side thereof has a support for fastening to the roof structure. The support includes a web that extends from the mounting to the support, a protrusion extending beneath the mounting and receives an extension that extends from the ridge-side cross beam thereof.

Abstract: A roof tile with a central brim and at least one lateral cover or water beading and a watercourse located between them, in whose region a water stop is disposed. This water stop is partially pressed with its edges in the region of the watercourse, of the central brim and of the lateral beading into the material of the roof tile blank. Such water stop is comprised of a flexurally elastic, thin small plate, and specifically of a material which does not conform to the material of the roof tile.

Abstract: The invention relates to an arrangement and a method for providing a roof tile with at least one water stop. With the arrangement it becomes possible to press a water stop, comprised of a material differing from that of the roof tile, into a roof tile blank. After the water stop has been pressed in, it is partially disposed with its edge in the material of the roof tile blank in the proximity of the watercourse, of the central brim and of the lateral beading.
