Leaky roof or roof window...?


Recommended Posts

Hi,

I have a ridiculous amount of water which runs down the inside of my roof, in the channel above the doors. Runs straight into the corner where it meets the windscreen, then drains right over my leg..... and dashboard..

Where to start looking, roof window seal or the joint in the main roof or sunroof...?

If it's the window seal is it best to replace it or a sealent type gunch...?

Cheers

Can be window seal, the roof leaking, or even condensation that accumulated on the inside of your roof...

This condensation happens quite often if your roof has been in the sun or a warmer area and at night things cool down quite a lot. You often do not see this happening due to the headliner...

I only noticed this after I had the headliner removed for intensive cleaning and drove the 90 around for a week in late autumn. Then it was not just the water running, but also the seats being wet from being dripped on...

Hi Yellow, thanks for your reply. This is definitely a leak due to the amount of water, also I have the front head lining removed at the moment after a bulkhead change that I will finish one day.

Think I'll check the seals anyway this weekend..

Mine did the same, eventually traced to the join in the roof where the bit over the front seats joins the main part of the roof - its the join directly above the door pillar that runs from 1 side to the other. Rain gets in then sits in the channel/pressing above the door, everytime you brake/ go round a corner it pours out in the corner above the door by the windscreen. Cured with a very thin bead of clear mastic, use masking tape either side of the seam to get a thin and neat bead of mastic.

got any pictures of what you describe?

mine does that after an encounter with a tree. it only does it if you leave it parked facing uphill when its raining and only on the passenger side. i have a roof with ribs on the outside, mayeb this is a different situation.

Not really as it involves taking all the headlining out to show the channel where the rain collects. On a 90 the join in the roof which leaked is where the two curved sections (which sometimes have alpine lights in - mine doesnt) and the flat section that joins them together, attaches to the sloping tapered bit over the front seats. Its the passenger to driver side join which is approx 6 inches behind the door pillar - that is the only seam that goes from one side of the roof to the other.

Mine was particularly bad so that water came out in both corners inside by the windscreen pillars. I could never actually find a hole though visually.

If you use masking tape either side of the join, you can fill the space in between with mastic. Then pull off tape and you have a neat seam.
