Leaky Sunroof

Hello all,

I have already tried to search for info on this topic but couldn't find the specifics that I am looking for.

I, like many Defender owners, have a sunroof that is leaking. It has already been sealed up prior to being owned by me and I have attempted to seal it again just in case it was a bad job initially. It is still dripping in my lap. I contacted a local Defender enthusiast who told me that the water dripping on my lap is due to the rubber seal sweating, has anyone experienced this? He said it won't happen during summer and I will just have to put up with it over the winter months.

I really want to try and remedy the problem so I have a couple of ideas I want to run past everyone.

1. Removing the sunroof completely and fitting sealed plate over the top of the hole - not the most ideal scenario as I would really like to continue having the natural light effect in the cabin.

2. Remove the sunroof and fit a piece of toughened glass, that is sealed in place - this would be a preferable option, depending on how the attachment of the glass to the roof panel, can it be done using similar means to the alpine or rear windows?

3. Remove the sunroof and fit a piece of transparent polycarbonate, sealed in place - another quite preferable option but depending on the same answer to number 2.

4. Just stop being a picky sod and put up with it - probably how the majority of answers to this will come back as I'm sure a lot of you have looked at these options previously.

Thanks in advance for any constructive, positive or indeed negative comments!!

Shane.

I removed the glass and cleaned the seal with WD40. Mine was dirty after 17 years of wind and dust. It hasn't leaked since.

Is it leaking or dripping condensation?

Is it the rubber seal for the glass or the frame to the roof seal?

Sorry for the late response. Been out of the country for a couple of months.

It seems to me as it's leaking. I'd heard of condensation being an issue but it seemingly leaks a lot more when it's raining, to the point that my seat bottoms are completely soaked.

I will be placing some aluminium tape over the gap between the glass and roof to see if there is still a leak, if so, I will assume it's condensation, if not, I need to work the roof using a method earlier mentioned.

Thank you for the responses so far.

Try this, I did it and not a single drop since

Get a quarter size piece of plastic that has a tiny bit of "give" to it, think of a miniature hockey puck, after you have tightened your sunroof as tight as you can pull down on the round tightener, this will pull sunroof a bit tighter against seal, then slip your little piece of plastic, mine is about 3/8 inch thick, between the glass and the tightener, and voila! No more leaks!

If anyone needs a picture, kindly let me know....

Yes, please post pictures!
A storm came through yesterday and I had about a 1/4 cup of water that was collecting in the headliner... Unbeknownst to me, when i drove the truck, the water streamed out at the driver side A-pillar.

I suspect the rain water is coming from the sun roof seal.
I also noticed there is a seam that cuts across the hard top (at about the b-pillar) ... could that be a source of water ingress as well?

I feel I really should remove the headliner just to be absolutely sure. Thanks!

Hope this helps. You can see a bit of compression.

Thanks, Kevin. Will give that a try.

Of course, I still have (I think) a water intrusion between the roof and the sunroof frame.
Then, I was at the big box hardware store this morning and saw the flex-seal - "handyman in a can! LOL..

Anyone tried to use this to seal around the roof and the sunroof? It's a bit unconventional way of problem solving... but curious what others think.

Disclaimer: Not a spokeperson for flex seal. never used it. Just looking to stop leak into cabin. Click image for larger version

Unfortunately, my sunroof does not have the circular opening mechanism, it has a handle that you pull forward and upwards to open it. I don't think it is aftermarket as it has the LR badge on the handle.

Instead I temp repaired it using aluminium tape as shown in the photo. After a few rainy days in the UK it has proved to be fruitful, no more damp seats to sit on, meaning it is a leak from the sunroof and not condensation. Now to contemplate a permanent repair solution.

Someone must hated that individual.

Anything that expanding foam is touching is permanently ruined. I can see full body repaint with all new weather stripping. Or that is what I would want.

OP, Have you tried removing those aluminum tapes against the paint? I would heat it up before peeling it with hopes that it won't lift paint.

Mine leaks water and I live in Seattle. I think flex seal would work but I wonder if there is enough space for water to accumulate, I feel like it will never dry and cause some serious problems down the road.

The roof needs a complete paint restore anyway which is why I wasn't fussed about putting the ally tape on. That stuff is used for aircraft battle damage repair and can withstand 600+ mph! Not that my landy can get much more than 10% of that speed

That is why I asked. I have used some aluminum tapes and they are rather permanent or the adhesive residue it leaves behind.

Just wondering-do you have a headliner? Might be worth pulling it so you can be d
Certain it's not leaking between the frame and roof.
As for glass to roof leaks, I've seen people use that grey door foam seals before now...

I do have a headliner. A job for a free weekend when the weather stays nice.

Can you buy replacement seals for the sunroofs or will it have to be a complete replacement unit?
