I'm a newbie
Now that it's started to rain more I'm noticing that a good amount of water gets caught on the roof of my motorhome. I've noticed when I drive out of my carpark that a LOT of water sluices from the roof, and I can also see it when looking down from my upstairs apartment. It's only maybe 0.5-1cm deep and covers the main middle section of the roof.

Is this something that I should be worried about leading to water ingress? I expected that the roof would be shaped to prevent water catchment, or maybe the roof has sunken in partially?

Thanks for any advice. :thumb:

it's normal :thumb:

when parked up/stored for an extended period try parking on a slight sideways slope..or even on levelling blocks to one side only...then the water will run off instead of pooling.

Pretty common problem as most vans have a flat roof. Luckily where mine is parked has a slight slope so it runs off. As previously suggested use levelling blocks to 'unlevel' it

Hi I've been a wild camper for over 23 years. My German coach-built has this phenomenon too & it is a 1992 model. I've had it over 9 years now & I don't have any structural problems or leakage.:Smile: I think most modern coach-built motor-homes are aluminium and are pretty well sealed against this.

I hope this helps:winky:

Just drill a big hole in the middle of the puddle, and all your problems will be over






:winky:

How silly! All the water will run down inside and slosh about on the floor. :Doh: I'm not that gullible. I'm going to drill a hole in the floor first so it can run straight out. Simples!

I had the same on both my Eura and Hymer.
Drowned someone once.

To get out of my road (back then) it was two very slow t junctions then one where you had to pull out really quickly.

The water didn't normally come off until I braked at the next junction. On this one occasion coming out of the T junction turning right someone stepped out in front of me. So from full acceleration with right lock to standing on the brakes:ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO:

The whole lot flew off the front passenger side and totally covered the bloke....... All I could do was look apologetic whilst thinking serves him right for running out in front of me...:Blush:

roof water

Hi yes, we have the same problem, weve decided to bite the bullet and buy a breathable cover. We can see the puddle forming on ours from our upstairs windows too. It is a real pain I know, but it does seem quite common.
