    Z3 Roof Leak!

    Hi Guys!!

    Sorry not been around for a while, had some problems, but all is good!

    I have an issue with the roof on my Z3. The back window is zipped in and on the bottom corner on the drivers side, it is leaking. And when I say leaking, I mean Pissing in!!

    Someone suggested some waterproofing spray, would this work do you thing or would I be better off a) getting a new zip fitted, or b) getting a whole new roof?

    I'm guessing it's a soft-top.... I've been online & seems like you aint alone, as Z3/Z4's do experience roof leaks sometimes.

    How about:
    - Adding "clear silicone" around the area (where the gap is) around the seals.
    - Sometimes others replace the rubber seals with new ones from the Stealers
    - Others go as far is using Gorrilla Glue (as an alternative to Clear Silicone)

    Ofcourse these are just the most common remedies people do on their convertibles.

    Maybe other vert owners can also shed more light to it

    Good luck!

    Re: Z3 Roof Leak!

    Is the water comeinng through the zip? Or the material?


    If it's coming through the material re-waterprofing with something like fabsil

    If it's the zip, some sort of vaseline or grease (as suggested) would be a quick fix

    the clear plastic window is attached to a black surround - if the leak is through there then time for a new screen TBH, any remedy being short lived and difficult aesthetically.

    if the black surround is ok then water is going through zip or material:-

    if it's the zip leaking the the fabric has come away from the black surround (should be neatly tucked under it) and water is channelling in their - I got a tube of black stuff from ECP that does the job nice (i will dig the stuff out if you want product name?)

    if the canvas is tight into the black surround then likely the seam/canvas is worn - I'd try fabsil if thats the case (ebay).

    if that don't work it's a trip to Jack Smiths for new roof.
