Hi my son has a merc vito   montaray   with a leaking  roof its where the roof meets the cab  it has a plastic strip that runs along the side I presume to cover up the seal ,  I have been to a few repair places around and most of them say fill it up with foam, because if the strip is removed it could be worse underneath  has any one any suggetions

Most leaks seem to come from the Windscreen Seal , another place is the rubber around  windows in the Hightop version I doubt a leak from behind the join cover strip.
Just try using a hosepipe on a spray to try to simulate rain try this in various places until you find the leak. My bet would be the roof windows if a Hightop

Agreed - if it's the high-top, the upper windows are a more likely source for a leak - the water tracks down behind the trim panels, so you may not see it until a lot further down.

Whatever the cause, avoid using expanding foam - it's not a good seal, and if you don't get the place where you are applying it completely dry it can make matters a lot worse, as the wet can spread by capillary action between the foam and the underlying metal panel - which does ~not~ improve the situation!

Had a leak this summer in our 2002 Symbol nearside front behind the drop down sun visor. After a bit of exploration I suspected the windscreen seal. National Glass removed, resealed and refitted the windscreen, with new rubber seal and warranty. £90. All seems good!
