Condensation could be a contributor and weak seals. From a fellow Wet Knee Syndrome driver 1988 V8 110csw. I Like the roof lining idea though. Sadly I go rid of my 110csw as the Sowesta over my Diving suit when driving during winter time got in the way.:oops: Just curious though if you could do a pressure test in the cabin, would that help the Ozone layer with fresh Oxygen leaking into the atmosphere in the country of London.:D
 
now before anyone states the obvious, I know pretty much every defender leaks but I have been trying to get to the bottom of a fairly serious leak in the roof of my 2003 td5 110.

So far I have
- replaced all the door seals (just in case)
- replaced the alpine seals (they were shot)
- sealed the gap between the windscreen and the roof (it was +5mm in places)
- had the roof seems sealed
- had the roof gutters each side sealed

Last night the rain was very heavy and this morning the water poured out of the gutters on both sides as I drove down the hill outside my house.

I've not yet sealed the little bit of gutter above the safari door but I can't see a leak path there. bizarrely it doesn't seem to leak when it is parked facing up hill but that is a pain in the ass to do where I live.

The water seems to gather in the internal gutters but I've no idea where it's coming in. Anyone got any ideas (besides waterproofs etc)?

It's def not condensation. It
Brilliant does it work?
The difference compared to a full bear roof in a 110 is huge, especially in the rain. To be fair though I normally have a full headlining and so the results are less dramatic when it is in but I feel it does make it a bit quieter, especially in the rain (which we have a lot of in the north west). I have another thread on my current noise reduction project https://www.landyzone.co.uk/land-rover/sound-proofing.320310/page-2#post-4076355)

I've started mine and done the footwels and boxes and bonnet. Made a difference so just roof and doors to do.
 
Time for an update. It has been frustratingly dry here for the last few weeks - not something I usually struggle with. I have found a small leak in the driver's footwell. Quite why someone thought two tiny circles of gaffer tape type material would keep the water out of those 5mm holes I don't know. I do know that they are stuffed with butyl putty and covered in big bits of gaffer tape now.

I'm not sure if the sikaflex over the safari door has worked because I haven't had enough rain. I have soaked it with a hose and not much has come in but the water from the roof takes ages to find its way in. So far though the gutters seem dry. The only water that did come in came from the front of the driver's side A post and then trickling back into one of the internal gutters. There is no longer a gap between the windscreen frame and the roof and so it isn't coming in there.

When I saw the water I took the sealant out of the top of the outside of the A post to see what I could see. There was a tiny trickle - almost seeping - out of the edge of the roof onto the top of the A post. All I can think of now is that it may be permeating in through the windscreen seal and then coming out the sides of the roof, some outside and some inside. The seal isn't brilliant but they are a pig to change and so I'm reluctant to try. Going to try some Captain Tolley's on it this aft. Rain forecast for tonight...
 
Almost a month later and its been a mixed experience to say the least! After all the work above I was hoping that the major water leak into the internal gutters would be sorted but it wasn't. There is some water coming in via the windscreen seal and that is due to be fixed next week. However the major deluge that comes in every time is rains when the truck is parked facing uphill continued...

A mate suggested that it could be coming in at the join between the front and rear roof sections. There are a pair of shallow dents in which water pools if the truck points up hill but a few months ago that had been previously sealed with sikaflex. However, when my local independent landy specialist (Track and Field Bolton) did some work on it for me this week he discovered that it wasn't properly sealed. When he was up on the roof, the joint opened up and water came out! He dried it with an air line and filled it with sikaflex. It now has a big black line across the roof but the rook is due to be repainted shortly so it doesn't matter.

We've had some rain and I've washed the truck and so far success - no water coming in.

Of course I have found a couple of new leaks... The vent seals leak when you put a high pressure hose on them which is fair enough. I've also got two small leaks on either side at the front from about half way down the door seals. The seals are good and there is extra sealant on the doors so I think it just needs a bit of fettling.

As an aside Wayne at Track and Field in Bolton is brilliant. He basically only does Land Rovers and people travel from far and wide to get him to work on their trucks. He's worth the journey.
