The roof join inline with the trailing edge of the door is worth a look, it was in my case.
You could also try parking up or down hill to determine the point of entry. |

Two other likely candidates - the alpine light window seals and condensation on the underneath of the roof as the weather gets colder. It probably isn't the windscreen itself. Donald

What Donald said. More than likely running along gutter inside from windows or near back. Is the gutter dry below alpine windows. Do you park nose down or park level and leak is worse when slowing?
Does it leak when driving in rain? If yes then its near the front Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

Same problem here. I've changed the alpine window seal and used Dinitrol seam sealant on what I think are all the potential entry points and it's still doing it. I need to get the roof lining out and have a systematic go at finding where it's coming in.
No more than a generous cupful of water generally gets inside, and it all empties neatly into my lap when I first go downhill, so the inconvenience could, I suppose, be worse. |

Do you mean the join across the roof sort of above the driver's head? donmacn No alpine lights so that probably rules them out ( although it is a Land Rover) and the roof is fabric lined so no condensation also it leaks in summer rain as well as winter jst Normally park level but is worse when slowing and having sealed the windscreen does imply it is coming from the back but being an 04 plate it does not have the little vents on the rear panel swt Yes empties in my lap as well |

Its coming in side or back and sitting in the channel then moving under braking. Roof join, also check rear roof return to back door at corner. All gutter to roof bolts are tight? Cheers

Cracked mastic sealant where roof lower gutter section is joined to the roof panels. Rake out the sealant all around the roof with sharp chisel and refill gutter with Soudal Carbond (not sikaflex as not repaintable).
99% of the time it is this and not the alpine window seals at fault. |

I had this too!
It was coming through the roof where the flat section meet the slanting front section. I used Captain Tolleys creeping crack sealer on it. Spent a few hours when it was dry and warm going over it every 30 mins and it hasn’t come back. |

If you can take the headlining out for a bit, then poke a piece of kitchen roll into the inner U channel above the door you may find that it is (surprisingly) dry, and that the water is not coming down that inner channel which seems like the obvious location.
It may actually be coming from underneath it. The way the roof folds into the gutter area is a bit weird in that several pieces make up the gutter and if the the mastic in there is cracked the water can get in under the upper layer of alloy in the gutter outside and appear inside. When I was building my lifting roof I got right in about it and was really surprised at the very convoluted structure and was finally able to determine where the copious amounts of water were coming from. Because of that folded structure water can actually come in anywhere along the sides and round the rear corner but all appear at the front in your lap (when cornering). Oldowner is spot on. The actual offending bit is very near the outer (folded) lip of the gutter and you have to really poke the mastic in there - its hard to actually see what you're doing, but worth making the effort, AND go around the rear corner too as it can be a contributor. After I put a couple of tubes of PU mastic in there I no longer needed to wear waterproof over trousers when it was raining! |

Another vote for Creeping sealer, though the leak was on the lower scale of things, the sealer did cure it.
Ad above, applied during warm dry weather, it dries clear, what you can see of it.[/b] |

Thanks for replies I think the consensus is tending towards the sealant in the gutter or possibly where flat and sloping roof meet so I guess now I will have to wait till the weather warms up to try and seal it.

When I suggested the alpine lights and condensation, I forgot I'd already sorted the roof guttering on mine.
There are some pics on my 'resto' thread, towards the bottom of this page. [url]https://www.defender2.net/forum/topic58538-15.html [/url] The last pic gives you an idea of the construction that jockland john has mentioned. On the 'creeping crack cure' stuff - I've been a big fan of that too, and it did stop a few leaks I was having. However..... after a week's offroad trip back in September, some of them came back. I suspect the crack cure stuff dries quite rigid, and then over time, or with offroad use, the body flexes enough to break the seal. I had to get the windscreen resealed a few weeks ago and he used 'arvomast' - as I understand it a more permanently flexible seal. I do now have a 'laptop leak' again, but now I reckon it's the alpinelights and I just need to go around them with the arvomast stuff. Hmmm - posting the page link didn't work? What do I need to do?
