Water Coming In

Other than the alpine windows in the 110, what are some known leak spots in the roof?

If it rains while the car is sitting, then while driving, and upon applying the brakes, water will run forward along the bottom edge of the headliner and pour out where the windshield, front door and roof line meet, right onto my knee.

I don't have a sunroof.

It is ribbed.

And I don't think it is rear vents since the water would have to go around the corner, then all the way to the front corner at my knee to drip there. I think it would drip someplace back near the vents.

But when you say the front panel main seam, do you mean the seam across the roof where the slope starts?

I have the exact same leak on my ribbed 90....I am going to take off the front headliner, but I think a fresh bead of sealer on the roof to drip rail on the sides and front and then fresh beads on the rib sides would prob get rid of it...

Yeah. I'm trying to weigh the problems I have with each car and figure out how to manage having a '65 IIa and an '88 Defender as my daily drivers. Having the water coming in is disturbing because I know it is just going to mean more money and another project down the road to fix what problems the water caused.

Looking at the roof seam, I'm not seeing any gaps, but I'm not seeing any calk either. Do any of you recommend a technique -- calk outside only, calk inside only, both? etc... Also, what type of calk has worked for people?

Everything you need to know about caulk

I have found with mine that water collects in the gutters then while braking runs to the front, when this happens the water spills done around the leading edge of the doors more so on the left hand side then right. The door gasket even though it is new is not a tight enough seal and the water comes thru right at the point where the door frame starts to sweep to the rear at the belt level trim.

Wonderful watching experience there, Jason.

Ryan,

I'm pretty sure the only difference is that this is certainly coming onto my knee from inside the vehicle. Because I can see it coming out from behind the headliner at the front corner near windshield. So, it's either coming in the alpine window (but I have not seen it happen) or it is coming in at the seam and filling up the edge of the headliner.... not good.

I replaced the seal between the bulkhead and windshield frame on mine....huge source of water ingress issues in my opinion looking at the design that seal should probably be replaced every 5-10 years....ultimately it is what causes a lot of the bulkhead rot same with the actual windshield seal.

Really?

It's been a known issue with Land Rover hard tops since the year after they were introduced. The easiest cure is to change to soft top.
The rain gutter is inside the roof as well as outside. The roof leaks at the gutter seam. You have gutter water inside, under acceleration or deceleration the water sloshes forward, spilling out from behind the headliner.

You are better to caulk from the inside of the seam but it is far easier to caulk the outer rain gutter, just not as effective. A more effective fix is to remove the roof from the gutter and refs stem it.

So... are you saying there is a seam between the gutter and the roof? And this seam, if open, would run to the inside along the gutter? Seems like an obvious place to NOT put a seam.

That's exactly the way it is on a Series and I think they didn't do it any differently on the Defender. My 90 only has a canvas ST so I can't confirm. A seam there is so they can have a steel gutter and still have an aluminum roof.
