Water collecting on roof

[our poppy llll]

So it’s been raining, if I look out of one of my bedroom windows I can see the top of my Moho. Being a swift Kontiki 2023, it has a raised front, commonly described as a bubble. On a slope with the back at the highest point, rain water pools on the roof at the area where the flat roof starts to rise into this bubble area. It’s about 1 cm deep but covers an area of around 3 dinner plates. So in order for it to drain away, I have turned the motorhome around. (All the water has drained away)
I was wondering if the water was left and I didn’t turn the Moho, would this be the long term cause of silicone deterioration and eventually water ingress?
I notice I now have a dirty stain, (which will wash off) where the water settled.. as soon as it stops raining I’ll give it a good wash. I don’t know if it’s worth buying a cover or just splash a good wax wash all over the roof. What’s your thoughts?

Get a pair of Tyre Savers.

That should raise one end of the vehicle a little and stop the pooling

 

[Burge]

As above lift one end slightly

Similar problem- what they say. I feel similarly to you regarding pooling and degrading of seals

 

[Spriddler]

On my drive one rear corner is the lowest point. The bonus is that the dirty water running off the roof is confined to only leaving streaks down a 2" to 3" wide vertical strip on the back corner making it dead easy to clean it off!

Do you drive on them ?

After 9 years mine a Kon-tiki669 lets in water.In for repair under Swift warranty.

I've had a persistent pool of water collect on the roof of my 2020 Geist since I got it on 2021. Just took it in for a damp check. Looks like seal has failed along the joining rail between the fibreglass bulkhead at the front and the main roof panel. Right where the water collects.

Yes.

Normally you would have a set of 4.
They are designed to follow the curve of the wheel and spread the load so that your tyre does not get a 'flat' by being parked on the same bit of the tyre for weeks on end.

If you only get two, then you park one pair of wheels on them and it will raise the front (or back) by a couple of centimeters.
Which should be enough to drain the roof.

If it's not, then screw the tyre savers into a plank of wood cut to the same size, which will raise the vehicle another inch or so.

The other option is simply to use your ramps that most of us carry to get a levellish camping spot.

Thanks for that but my car moves very little these days and is bound to.have flat bits . They look usefull before I get 4 new tyres .

I have a bit of wood under each front tyre to raise the front and stop water pooling on the roof.

 

[Jimbohorlicks]

Just use a ramp under one wheel to create a slope to the roof

Not an expert opinion but I would have thought that the worst thing for the sealant would be out in the open sun, heating, cooling, shrinking, losing adherence etc.
So maybe the water protects it.

Only if you have a bag of water same size as the roof and 3" thick
Otherwise, water will find the smallest pinprick of a seepage crack and work it's way through over time.

You need to avoid water pooling on the roof at any time

Mine is 3 years old and in for exactly the same tomorrow. Been in twice sealed then four months later slightly leaking again, just over the window above the battery seat. This time I have asked for the sealing strip from driver's side to passenger side to be replaced not just resealed. Have to wait and see what the initial report says.

Same as Jimbohorlicks we always park at home with a rear wheel on a levelling ramp, even when it has the all over cover, never have a problem with water collecting on the roof.

I have made a rope wick that sits inside a piece of flexi pipe about 18 inches long. One end sits under my solar panel cable in the puddle to stay in place the other end sticks out 6 inches to the side. The water wicks away along the rope and drips clear of the van walls. I haven't driven away with it in place......yet. I do need to get the ladder out to put it in place when I get home but it does the job.

I thought of something like that, but just couldn’t picture it.
It would be great if you could take a photo and put it on here so we can see what it looks like..

I don’t need to lift the Moho for the water to drain off, just drive onto the sloping drive instead of reversing on. Because my drive is curved and steep, to get plenty of space for other vehicles it’s more effective reversing onto the drive and parking horizontal to my garage, if I drive on to the drive, the motorhome sits at an angle to the garage taking 2 parking spaces.
When I reverse on if I use my front hydraulics, it barely lifts the motorhome level due to the severity of the slope. However I’m leaving it driven on to the drive which stops and water pooling.
Still waiting for the parts under warranty from Lowdhams. Once fully repaired. I can start looking to replace it.

Any good? Obviously it's convenient my solar cable is there but I'm sure there would be other ways.

Brilliant idea, I’m going to give it a go..

 

[our poppy llll]

So I’ve cleaned the roof, with a quality snow foam car cleaner, including a wax, I then used bobby dazzler on the roof. So I checked where water might pool and as it’s not raining relied on the wash I gave it, to see where the water might land, the wick is a piece of rope laid across the roof wrapped around the Ariel and hanging over both sides. Couldn't get a pic I’m too wobbly on the ladders today.
so I’ll wait for rain to see how it works.. I’ll report back..thanks the great idea.
