Hi

I have a 2010 Devon. Only noticed recently water dripping from radio speaker in the roof next to the habitation door onto the sink unit below. Not much spread yet, I guess that because it has found an easy exit it is not spreading to far. I have checked and sealed the upper brake lights on outside of vehicle (passenger side brake light was wet inside I had hoped this was the problem, but rained heavily today and still leaking) I have not taken the long brake light at the top centre but sealed round with silicone, I notice that silicone does not appear to be the perfect solution on other posts. The van also has rear camera which looks sealed but I have not yet taken off to check. The top of the van looks water tight, I had to fit a new nut on top as one was missing, again it has leaked in since doing that. Is this a known fault on the Devon? The roof light near habitation door seems to be ok, is there anything obvious that I have missed?

Cheers

Phil

Hi Phil, I have a 2010 Devon and I have checked mine and I can't see any evidence of damp. Could it be coming from the Awning area.
Cheers Peter C

It could be getting in anywhere on the roof and finding (as you say) an easy exit.  You need to check ALL roof light seals and if you have a Truma fire the seal on the roof flue, plus any/all aerial and cable entries on the roof.

Hi Phil
Also check the screws securing the fibreglass moulding cover above your recess awning, one or more screws could have pieced the outer skin.
I had small leak in that area as a result of replacing the awing at the dealership last year .

Thanks for all the feedback, the awning does look like it may have a bearing as the boarding on the inside is slightly bubbled. I had thought the awning was a sealed unit but if it is possible to puncture the outer skin I will take a look at that. Is it easy to take the external cover of the awning? It looks like a line of screws on top and a couple each end?

I had to replace the recess awning on my 09 Nuevo some years back , the cover had been sealed in place with sealant and screws, it was a hell of a job to remove it in order to replace the awning.
My Sigma had its awning replaced last August at the dealership, the cover was held in place with screws with 
Some sealant applied at the ends.
The workshop resitted the screws with sealant , leak sorted.

I used to have a Surrey which had a similar layout to the Devon and had a leak from rear skylight over the kitchen area, after climbing on to the roof I found that you could lift one corner of the rooflight with a finger, I resealed all round the rooflight which cured the problem, but as Peter said water can get in anywhere and travel to a different part of the roof to exit so as he said check all rooflight seals and possible entry points, good luck in finding the source.

Hi thanks once again. I have removed the awning cover and filled and covered all screw fixing with sikaflex 512, the old sealant seemed to have been weak and flaky in places, had a few wet and windy days since and touch wood this seems to have worked. I will monitor but hopefully job done
