I had the same problem posted by "E46_M3Power" user (7/13/2011). I think I finally fixed it after 2 years of trial and error. First I tried the silicone bead across the front edge where the canvas meets the rubber. That did not stop the leak. Next I tried waterproofing the canvas top with 303 Fabric Guard which you should do annually anyway. That did not work. I checked that the drainage hole and channel that runs down the side of the windshield was not clogged. It wasn't. Here is what I did: I used a 1/4" solid piece of gray foam insulation, the same material that you'd use to wrap hot water pipes (see sample of foam next to a US dime). Insert a piece about 4 inches long into the support frame along side of the roof (in the pic, the end of the foam is seen).

Nice - hope that it works long term, and that it will help many others. The round pieces of foam as shown in your picture are often referred to as "caulk saver" in hardware stores, and they are available in various thicknesses.

I have the same problem on my vert here in England its torrential rain at the moment and I cant seem to fix it. it seems to puddle on the rubber section and weep through! tried the silicone and treating the rubbers. the drains are clear. but I just cant put my finger on the cause.

rubbers seem in good condition but water is getting through. im getting that frustrated by it im tempted to change the top seal and the seal on the roof itself! but this is going to cost me a arm and a leg when im sure its a easy fix as its not leaking loads but enough to give my mrs a wet bum!

Actually no. Not solved. While shoving the foam strip into that crevice prevents water from collecting in there, water is still getting past the seal between roof and top of windshield. I cut a piece of 1/16 inch thick foam wrap (the kind you might wrap a fragile item with), placed it near the top of both pillars and closed the roof on it. It's been dry since I did this about 6 months ago but I haven't driven in a heavy rain yet. Obviously not a permanent solution but it might indicate that the rubber is not making strong contact in those areas. Will keep tinkering.

Mine only leaks when it's parked in such a way that water can build up in the top/ windshield junction. I mean really build up, like a thunderstorm. And it's in a nose down attitude.

Weird. I still haven't figured out quite what causes it

Mine only when parked, never when riding, even if it's storming.
