I have noticed I have this problem on my series 5 pageant. There are 3 hairline cracks on each side at the front, they could have been there for years as I only noticed them as I was using waterless wash and wax on the whole van to spruce her up for summer.
I have checked with a damp meter and have a reading of 20% Directly inside of the longest crack but this drops down below 15% within 5 cm in each direction. i cannot get a higher reading near any of the other cracks. I am hoping this means the unseen damage is not too bad. We always use moisture collection traps over the winter and I haven’t noticed any musty smells at all. There is also no bubbling or discolouration i can see.
I have used some sealant cum adhesive to cover the cracks for now and will keep an eye on it, damp wise hoping it dries out.
i have long been suspicious of the metal roof rails front and back so to see the tape used by the OP is really helpful.
I don’t have the cash for a new van or a pro repair at the moment so will have a go at the tape.
Can I just ask the op did you put the tape straight over the original roof seals or did you take the excess old sealant away first? It looks from the photos like you took some sealant away?
also appreciate it’s an old thread so any advice is helpful and thanks in advance.
