Sagging Roof Edge Strip Gasket

Recently while washing the car, the inner part of one of the black roof edge strip gaskets on my Cayman dropped into the gap between the roof section and the roof edge strip itself. I think that integrity of the gasket is important because it prevents water getting into the channel beneath the strip, although there may be a drain into the hatch gutter.

I partially removed the strip, faffed around repositioning the gasket and reattached the strip but the gasket still appears to be sinking into the gap (the warm weather perhaps?), so it appears that a new gasket will be required. I contacted the PC to see if replacement is covered by the extended warranty: "Sorry sir, gaskets aren't covered". Pants....!

I've noticed that on both sides of the car the outer part of the gasket fits better than the inner which sits lower in the gap, so perhaps it's a design issue. In fact, the whole roof edge strip and gasket assembly looks a bit flaky to me; it would be far better if the gasket was clipped or bonded to the strip rather than relying solely upon friction for its support.

Funnily enough, at an R10 meeting yesterday evening we had a look a a fellow member's Cayman which appeared to be suffering from the same problem.

Anyone else had the same experience?

And just as a warning, be careful if you're trying to remove cleaner residue from this area. If you press too hard it's likely that the gasket will disappear into the channel.

Hi Jeff I too have had same issue with rubber strip disappearing into the gap when cleaning. Seems to me that the gasket is not wide enough for the gap being filled. I managed to tease the gasket back into position with a very thin piece of plastic and i now make a point of avoiding the strips of rubber on the roof all together ! Cheers Andy
 
Hi Andy, FYI here's an exploded view showing the relevant components of the assembly (go to Main Group 8: Body and then 810: insignias): http://www.porsche.com/all/media/pdf/originalparts/en/E_987C2_KATALOG.pdf Apart from being secured at the front and rear of the roof edge strip (6), the gasket (7) is only clamped by the two clips (9) which also secure the whole strip/gasket assembly to the body, so the gasket section between the clips is supported primarily by friction between itself and the roof and edge strip. A very poor arrangement IMO and common to that used on the 997 too. You can pull up the roof edge strip at the front end but the rear is secured by one of those infernal expansion rivets (8) which are easy to assemble but tricky remove owing to inaccessiblity. Jeff
 
Interesting to note - the latest Cayman (981) has no gasket or slots for a roof rack etc.... maybe it's now too curved to work with the old style Cayman fixing. Chap from Silverstone OPC reckons there will be a new roof rack, but it's not been announced yet.
 
Stu, I see that a rack is now available for the 991, so it shouldn't be too long before the 981 follows suit. Looking at some pics for the 991, the rack fittings seem to fix into the seam between the roof and side-rails and I think that the 981 will follow suit. As you say, it looks as though Porsche have eliminated the (troublesome?) roof edge strip on our 987s. Jeff
