Getting to know the new van, on roof making sure all was well and found the very worrying situation shown in pics below.
The adhesive had stuck very firmly to van roof but had given up on the plastic support.

I had in past found getting plastic to stick can be troublesome as some types refuse to stay stuck unless using the correct adhesive, I believe the correct one is Sikaflex 552 AT.

As the dirt shows it has not just occurred, Drove it back from near Bremen in Germany like that!!

Lucky it didn’t blow off the roof john, I always use sikaflex as that is the one they recommend for van sticking.

You were lucky there. Glues and screws for the repair?

I looks like they just put it around it rather than under it or pressed it down so hard it all squeezed out, I was advised to use Stixall John, and to put a couple of matches under the brackets so it couldn't squeeze out, Sika is made by the same company now.

Is there any way you could attach some right angled aluminium brackets to the panel and sikaflex them down instead?

Kev they had actually coated all of the available surfaces with the adhesive and it was a decent thickness, it had simply parted from the plastic, as I mentioned previously I think they used the wrong product.
A few years ago on a previous van, I made and fitted (stuck with Sikaflex 221) some aluminium rails for my windsurf stuff, when I came to sell it a few years later I wanted to remove the rails to put on the new van they took hours to get off of the roof, only way was with fine wire and lubricant used like a cheese wire. 
A while after putting the rails on I had to install a new roof vent realising I didn't have any of the sealer strip I would have normally used for the installation I used some of the Sikaflex left over from the other job, all went together nicely and thought job done, some months later we were away and it was absolutely pi***ng down, Pat went to use the loo and told me we had a leak, water was running in from around the vent, when we got home I took the vent out to find that the Sikaflex whilst stuck very firmly to the roof had not joined the plastic of the vent at all, made the repair with some sealer tape and all was well.

Pete, exactly my thoughts.
