Yes I’m afraid so. What you need to do is lift the roof a bit and pull the rubber seal down. This will give a much better idea of what’s going on. Can’t comment on the repair bit as it has changed so much over the years. From full roof respray to rubbing the paint back under the seal and coating the alloy then sticking a new seal on.I know this is well documented but can someone help me clarify whether this is roof corrosion, or something else? This is on a 2015 T5.1 Beach. I thought corrosion on the T5 was really the front cap and sorted for the T6. The front cap looks fine. But I have spotted this on the pop up roof, at the back.
I got the van 2nd hand from Crawley. When I phoned SMG Tonbridge where the can was originally from, they said it was on the roof corrosion list and would phone me back with updates as the van was transferred to me. I have it going back there for an MOT and service next month, but when I asked about roof corrosion again they said it wasnt on the list.
So I don’t want to be fobbed off and lose out. Looks to me like minor roof corrosion, but want to be sure. It is hard underneath the bubble, not soft and flakey paint
And surely as it is the roof, it must be quite easy to replace the whole roof? Anyone had this done and even if outside warranty, know how much this roughly costs?

Having seen some of the horror stories about work, if this really is cosmetic, I’m tempted to put down 3M tape and leave it. Let’s see what garage says!It does come off fairly easily but can take a bit of paint. Apparently it's purely cosmetic, as it is the aluminium "bubbling" rather than rust.
I’m with the ombudsman and trying to get everyone an extended warranty... how far did you get?Re: BLISTERING ROOF PAINTWORK - SURVEY
I totally agree. Corrosion can't be fully solved unless it is accessed from inside, which it appears not all dealers are doing, although I would have thought there must be a set repair procedure laid down by VW.
The warranty issue is something that we hope to clarify. There appear to be three aspects to consider:
1. Corrosion caused by "defect in manufacturing", ie aluminium roof section not satisfactorily insulated from steel bodywork, resulting in electrochemical corrosion, would presumably be covered by the General 3 Year Warranty.
2. Corrosion caused by poor paintwork will be covered by the Three year Paint Warranty.
3. 12 year protection warranty. This clearly states "bodywork sections and panels covered against rusting through from the inside" so it probably would be interpreted that however bad the bodywork is on the outside, if there is no panel perforation, it wouldn't be covered.
Therefore I feel that owners who think/hope they are covered for 12 years are being rather optimistic, unless we can shame VW into giving us a 12 year warranty to restore Cali owners' faith in the VW brand.
Glad to hear that at least they provided you with some form of alternative transport for the month(!) it took to repair.
Same here, SMG did the ”tape check” over a year ago and added me to the list. I rang recently to get confirmation that I hadn’t been forgotten and they confirm that I’m still on the list.It was was flagged by SMG Cowfold on my 2012 beach during a service 1.5 years ago and so they put me on the waiting list but explained that it would be a long wait as only a handful of garages are authorised by VW to carry out the work; But not sure now if I want the work carried out given some of the posts on the forum. I only have a few small minor bubbles on the paint.
Had ours (re) done end of last year with latest fix including front cowl. Tried to get a commitment on warranty for work but told it is a good will gesture and not warranted.
The 6 years was the “special” extended warranty from new, so any warranty roof repair on a 6 plus year old Cali would rely on VW offering a guarantee on the work. From previous posts it seems that VW offload the responsibility for the quality of the repair to the body shop and expect them to deal with any claim.Ive been told 6 years....
Mercedes are replacing roofs on the Marco Polo which are GRP. Some are on their 2nd replacement roof.Our 2012 roof had corrosion and was done previously by VW in 2017. Needs doing again and is booked for November this year for repeat repairs.
The previously repaired front cap has failed as the mastic/sealant has peeled away in places and there is noticeable movement (up/down) in the cap around the joint - no signs of water entry (fortunately) yet, but keeping a close eye.View attachment 79725
I've also got corrosion on the corner brackets on the underside of the lifting roof (one in each corner that bolt the aluminium roof in place (note 'spots' in top right of this image are water spots, not corrosion spots!)
View attachment 79727
And I've got the ubiquitous corrosion spots just above the rubber trim around the perimeter edge of the roof.

I've had to pursue via national customer services team as no proactive approaches from local VW dealer. Went to an alternative dealer who (politely) refused to get involved saying it had to go back to the dealer who undertook original repairs. National VW customer services insist it has to be inspected and 'logged' by an a official VW dealer in order to process the repair, - when i got customer services involved even they struggled to get responses from my local dealer!!
Seems to me that VW could have saved themselves an absolute fortune by replacing the aluminium roof panels with a GRP unit, or probably even a carbon fibre version (!!) that wouldn't be prone to the continued corrosion issues.
We had a GRP roof on our T4 California and it started to show signs of stress after 9 years. It started with the name on the front starting to peel off. The rest seemed ok at that point but I thought it was a message to upgrade and moved to our current T5. It did have 4 big black bolts in the centre of the roof which always struck me as a weak point.Mercedes are replacing roofs on the Marco Polo which are GRP. Some are on their 2nd replacement roof.
My van is a 2008. It bubbles a little and then some years it seems to disappear. Given it’s not actually rust I’ve decided to leave it be.It was was flagged by SMG Cowfold on my 2012 beach during a service 1.5 years ago and so they put me on the waiting list but explained that it would be a long wait as only a handful of garages are authorised by VW to carry out the work; But not sure now if I want the work carried out given some of the posts on the forum. I only have a few small minor bubbles on the paint.
How did you manage to get VW to repair your roof corrosion ? They flatly refused to repair mine when the van was 6 years and 6 weeks old ."None structural parts are not covered by the 12 year corrosion warrantee" The 6 year limit was strictly applied. Or was my dealer just useless at dealing with VW?My 2013 T5.1 SE is due to go go to Marshall’s in Newbury for the main roof galvanic corrosion warranty repair.
I would be interested to know if anyone has had the repair carried out at Marshall’s, any feedback would be much appreciated.
Still undecided as to whether to trust VW with the repair after reading some of the stories on here or to foot the bill and use a recommended independent.
Does anybody have any recommendations of a suitable independent?
Thanks in advance.
Sorry for dragging this up WG, but Sinclair‘s have just said that VW has refused my claim for repairing corrosion around the edge above the rubber strip (they repaired the front panel in 2017 due to corrosion).I don’t think so, in the U.K. if there is corrosion present on the edge of the elevating section, minor corrosion is dealt with at the Dealership and major at a body shop before the tape is applied. There is No Cost for any repairs required.
Apparantly all California’s from 2010 onwards are covered, in the U.K.
