Discovery 2 Leaking Sunroof

Morning All. I have a 2004 Discovery 2 which I am very happy with except for one niggling problem, a leaking sunroof. I have had it to 2 separate garages and changed the seals and still it leaks. I am now told that it could be the sunroof drains. Has anyone had a similar problem? If it is the drains how did they resolve the matter? Did this involve any welding? If any one can advise I would be very grateful.
Many thanks,
Howie
