The vertical tile cuts are spot on with the velux installation instructions, there is no mastic/glue on the bottom of the tiles just a years worth of grungeCut the tiles close up to the window and don't be tempted to "glue" the bottom tile with mastic as pics above...can hinder water getting down and out from secrete channels, this then promotes the breaching of the perpendicular side flashing.
