    This is not exactly a hypothetical question but at this stage I don't want to give too much detail online.:cautious:
    I've seen this quoted:
    I've quoted that figure as it is relevant and the motorhome would need to be returned to the converter.
    I'm not too sure what a "full stripdown entails". Is it simply a question of undoing some bolts and removing a panel or two or is such a roof repair more involved?

    The damp is now visually evident in the form of a small patch of light blue staining and the start of rippling in the ceiling. I don't know why the staining should be blue, I assume it's something they use in the manufacture.
    The point of water ingress is through a joint in the roof and the staining is immediately underneath this area.

    The roof exterior panel is one piece so the whole roof needs to come off.
    The outer skin is bonded to the foam core, which in turn is bonded to the inner ceiling board.

    The outer roof skin is glued to the walls via a wooden framework, which may also be water damaged.
    I doubt very much a major repair job would be worth it and a whoe new roof would be a far easier and cheaper option.

    Not a DIY job thats for sure and as for expense......it could, and probably will, run into many thousands of pounds.

    All the above depends on the exact extent of the water ingress and severity of the damp.

    If it's a proper joint in the roof , can't see the whole roof having to come off, can't you just re seal the joint , how old is the mh , is it under any warranty , if so I'd leave it to them if not it would be worth getting a ceiling board down and having a look cause if you are going to have it repaired it will have to come off anyway, or if it's really old just seal the roof and leave it as it is.

    One piece roof skin or not, the roof panel is still bonded to the foam core and wooden frame.

    If it wasnt, the roof skin would vibrate when travelling and would have little strength.

    Thanks for the replies.
    The motorhome is 11 months old so still under warranty. The highest level of damp measured is 55%.

    No question then let them get it sorted, or even go for a new one

    11 months old - with a reading of 55% it's been leaking since it was built!

    You're absolutely right!

    That's the nub of the matter and reason I asked the question about what needs to be done.
    Do I really want a motorhome that's essentially been de-constructed and then re-constructed? I suppose you could argue what a fantastic "new" motorhome that would be then, but we don't really expect to buy something like this new and be happy with it being virtually taken apart to make it "proper" during it's first year.
    I'd love it be replaced by a new one but have I any real grounds for expecting this?

    I don't have an issue with the brand, I still like it and my relationship with the converter and dealer is still good, however it's taken over my life these past few months.

    a 55% reading isnt damp, its wet!

    you can get a high reading if the water has just started to get through, especially after heavy rain.

    its likely repairable, but will need the ceiling boards stripped to dry the core and then replace after curing the leak. i know of a few vans have had repeated leaks from roof seams repaired. so long as its done quickly and properly it should all work out ok

    if its been leaking from new, it will need timber and insulation replacing and a bigger job

    IF you have both the dealer and manufacturer onside then that's a good point --Try asking about a replacement and see what is said,before going into name and shame/legal,rejection mode:)
    I personally would not accept a repair if it was avoidable but it may be your only course of action,unless you go down a long winded legal route to reject the van --without knowing the make of van it's hard to second guess what can be done but I imagine complete roof off dried out and a new one on:eek:Then again I also envisage damp going down the sides and all sorts of problems stored up for the future -damp into electrics,things shorting out /not working the list is endless--I bought a known to me damp van and ended up ripping everything out after fitting a new roof on it -the wet (not damp:))got into everything --ask yourself will the dealer or maker simply strip out the roof or keep going until all the damp is gone?IF POSSIBLE see the reaction when you ask to reject the van;)

    Must be terrible to be in this position, as many more on here have been, you have spent a considerable amount of money on something that you can't use and will never be like you wanted, if it was me I'd be gutted, and really would be wanting a new one like I had paid for, feel for you mate but can't suggest how to go about it I'm afraid , if you go to law and lose you are further in debt for something that's is no fault of yours , maybe the petrol and match idea ain't a bad one:(

    55% hand the manufacturer a box of marches and a gallon of petrol and don't let the warranty run out it's probably to damp to burn

    Thanks for the replies people.
    I shan't be naming and shaming because I have no cause to and it would be counter-productive. As far as legal costs go I've discovered that we have legal costs up to £50,000 provided by our home insurers but I haven't yet instructed them, just had a conversation.
    In a nutshell what I really want is a new replacement, as I said, I still have confidence in the manufacturer. If I ask the dealer for this myself there is a high probability that I will be ignored, hoping I'll get tired and go away although a softly softly approach may reap benefits with dealer and converter not getting adverse publicity.

    On the other hand a guns blazing approach with a solicitors letter to kick off with may be the way to go.

    Problem with a leak is that it spreads like cancer even with a replaced roof there will have been water in the side walls etc

    On an older van it kind of goes with the territory few vans never have a leak but 55% reading is soaking my old 94 euro mobil had warped side walls etc from previous leaks yet only had 34% reading

    It was an 8 grand van so not that big a deal but at 11 months old yours is obviously worth an awful lot more than that but really the only way to fully put right is to remove every part with a trace of water which they probably won't do and would you ever really trust that they had? ......i fixed a leaking skylight on mine when I bought it and 10 months later im still paranoid when it rains ......if it's not been caused by anything you've done and been leaking from new then they've sold faulty goods and should be forced to replace it they can then repair that one and sell as a repaired van


    I know you don't want to divulge the manufacturer but can you at least tell if this is a British make or a European one?

    I'd never buy a British made van again continentals are so much better built

    It's a UK built motorhome. Looking through the web I came across someone who bought a new Dethleffs and had trouble literally within hours but I take your point completely.
