Problem with Water on Roof!

I always try and get the van level, however like the comments above, recently realised pooling was happening - (when drove off lots of water down the screen!).  Worse still, water started leaking into the habitation area!  Picture taken after most of the water had entered the van!  Took it and it was fixed under guarantee - not sure what they did though, they mentioned awning seal.  Now always try to be slightly off the level!

We had this problem on our Nuevo. Its parked on the drive front down, water collects till it reaches the roof window then drips inside! I now lower the n/s air suspension, and pump up the o/s, this is just enough to stop the water "pooling" behind the aerofoil dam.

"Its parked on the drive front down, water collects till it reaches the roof window then drips inside!"

Mike, that's not good. most dont have air suspension that can mitigate against the pooling you describe.
we have four roof lights, solar panel, auto satellite dish, roof exhaust for fridge freezer, exhaust for SOG, roof aeriel.
with slight nose down stance and completely flat roof, water eases forward guided by black rails each side and exits at front quarter via curved roof edge profile.
makes roof really easy to keep clean with no pooling ever......and rooflights should certainly not leak!
i can see that a van with a raised front 'overcab' would prevent water from running uphill, but in this case, surely other elements of the roof design must look to shift water, not retain it? 

Hi we’ve noticed the same issue with the roof collecting an excessive amount of water on our Malvern or as this morning ice has anyone challenged AS to actually do something about it and not be fobbed off with the excuse of that how they are designed?

I haven't challenged AS on this issue but I have on other unrelated issues.

Let us know how you get on Caraman.
thanks

Huh! We are newbies to Moho's and we have a new preregistered 2019 Broadway EB which we got in September 2020. On second trip out we had a leak through the roof into the bathroom cupboard - soaked everything. Our dealers were quick to fix it in fairness to them but they claimed it was a leak where the aerial goes through the roof. I have spotted that puddle collecting along that dip and seam several times when I have checked the roof. on a couple of occasions it has been so deep it has spilled across that seam towards the aerial area - we have a huge dip - you can see it when you put your eye level with the roof side. We get the cascade waterfall every time we move off from storage. 'Designed that way' my ars....  ....if is purposefully designed that way I would love an engineer to explain to me why. 

All the tips above are really helpful so thanks guys....its always hard being a newbie to something - steep learning curve.

PW Boy.
I suggest you still tell AS.Not likely to change without a lot of complaints.
The aerial was not sealed correctly in the first place as well.

MTB - we have registered our concerns because we also had a huge amount of snagging on a new MoHo as well. It fell on deaf ears I think.

Sorry to hear that Steve.
I thought things were improving.

Hey Micky. 
We aren't at all disappointed with our Broadway EB - we absolutely love it. However, we were a little surprised to get a lot of snagging - the roof issue and leak was one but we have also had snags with radio, warped draws, opening draws whilst under way, broken locks on toilet cassette door, trim coming away, leaking in the roof space, leaking in the bathroom cupboard, faults with the truma heating panel, a faulty reversing camera and now the bathroom wardrobe is pulling away from the MoHo side wall and we have a 4mm gap.

Our dealer to be fair has been excellent and has completed repairs very rapidly. The wardrobe one we are leaving for the moment - if it doesn't widen further we will leave it as it is. 

Other than these snagging issues - it is a great MoHo, although we don't have experience of any other to be fair, with which to compare it against. we like it and we are happy with it and I guess that is what counts

Snagging....??

When listed as above, you can see how many issues there are, I count 11. I've heard of folk rejecting vans for a list like that.
Sounds like it wasn't put together particularly well, then didn't get too many checks on the production line nor did anyone seem to bother with a PDI....hmm.
If a section the roof is permanently under water (other than when it's moved) then this puts a great deal of onus on any seals immersed....as you say, not great design...in fact, crap design....water (where it shouldn't be) kills vans.

I can guess where PWB bought his van. If I'm right, the PDI will have consisted of counting its wheels. 

So if you discount the third party fault/breakdown issues, then by my estimation, that leaves 70% poor build quality, an absolute disgrace.

Well we’re up to 9 faults and we’ve manage only one night away since purchasing in Nov 20. From that one night the fresh water pump failed, taken straight back to the dealership then set up for winterisation until visit to storage to collect for new cab blinds to be fitted and discovering the waste tank alarm blaring away and showing 100% even though fully drained down also battery alarms standing. MH now booked in for Monday at dealers for all the faults plus AS electrical issues that seem to be in all 2019 onwards then the following Monday to Mercedes for their electrical issues to sort but a word of warning on that Mercedes at Doncaster have told me that I will be charged if they find the issue is AS and not theirs so now AS dealers are providing a letter of proof that it is on the Mercedes side. Would we have bought a MH if we had known the issues with AS models. No

Tobe honest faults/snags can occur on any make.
Its how the dealer and factory resolve them that counts.
Its frustrating but i am sure you will be happy soon.

A 'fault' that isn't foreseen might be something like an appliance developing an issue soon after purchase...this probably wouldn't have been possible to pick up at build/PDI time.
However, I don't put misaligned drawers, wall units not connected together properly as 'snags'...the van should not get to the customer  in that condition....should be picked up at factory cross checks (are there any?) or if it escapes the factory, then at the PDI (again, are there any?).
Some of these can be caught by a diligent customer who is prepared to do his own 'PDI' prior to handing over the balance.
The thing is, so many are blinded by 'new van smell' and can't wait to pay and drive away...

I think there is a difference, as BB was pointing out, between faults which develop and poor build quality due to appalling lack of competency/care/inspection during build and PDI. The first may be just one of those things that happen. The second is inexcusable.

I've probably posted before of the brand new Symbol we considered buying. The interior wall was warped to the extent the washroom door would not close properly. Can anyone seriously believe this was not spotted at the factory or by the dealer?

Our issue with Fresh water pump falling should have been picked up at pdi the dealership service dpt found it positioned 2” from top of the tank and didn’t understand how we’d managed to get it primned in the first place the indication faults, excessive water on the roof are  consequences of basic poor manufacturing or design.
