sealing a tiled pitched roof

[sportsteralan]

Anyone got info on products that will paint on top of tiles, and waterproof the roof. it has Marley tiles on a pitched roof, and I have found some paints, such as Fibrecoat, which has fibres in the liquid, to fill gaps, etc, but is it effective and lasting, and which is the best brand to use please ?
Cheers, Alan.
