That will look nice .
I am on the verge of needing a new roof have been toying with a colour change
Uk model Orinoco edition all seem to come with a black roof but European spec models quite often come with a beige coloured roof which i quite like

My only reason for not full on committing to this is i am worried about how clean it will stay and how easy will it be to clean if getts dirty.
So may end up with black again.

I discussed having my roof a beige colour with Paul at The Soft Top Shop. He said they become dirty very easily and are s nightmare to clean so hence, my car’s black roof.

This leak in the boot has to be a leak into the boot - without stating the obvious! The bulkhead prevents any leak from the roof into the boot so look again at anything that will let water into the boot area.

A leak into the boot? The bulkhead prevents such so I’d look again at where the ingress is.
There is no 'bulkhead' as such. Just a continuation of the metal pressings from the rear 'shelf' behind the seats up to the 'scuttle'. That pressing has multiple holes stamped into it for all sorts of clips, cables, etc, so water leaking past the seals of the roof could easily get into the boot.

The most likely culprit of water getting into the boot, or the rear of the car from the roof are blocked drains from the continuous drain channel for the roof which drain out of each rear wing.

Before splashing out on a new roof (which won't cure blocked drains), I would take the rear wings off, the carpet behind the seats out and see if the drainage channel is blocked.

At the back where the fabric attaches to the rear deck is a fat rubber trim thing that clips in all the way around the rear deck. But that rubber trim is not really a seal. It's not meant to stop water. It just stops the fabric flapping against the metalwork. Pretty much cosmetic apart from that. The guy changing the roof won't replace that rubber trim.
Absolutely.
The rubber is designed to allow water to pass above and below it, into the moulded drip tray and drain via the wings.
The only proper water seal are two butyl strips behind the plastic 'piece' which is bolted to the car.

Take the rear wings off??
You rebody guys are extreme!
Surely there’s an easier way? Squirt some water round the seal and see where it comes out?

Taking the rear wings off is simple and quick. A dozen self-tappers is all that holds them in place.
You could possibly access the drain outlets by removing the rear arch liners but with the wings off they are easy to get to.
The photo shows the rubber drain tube (one each side) sticking out with the wing removed.

Best one I have got. There is at least on large hole where the CD changer bracket bolts from the boot side. I am sure there are more but not easy to see in the picture. The cables also go straight into the boot and the grommets aren't watertight.

That's a good picture @Pond there are multiple places where water can get from that shelf into the boot. But, as I said, if the roof leaks at the back then the carpet trim on that shelf will be wet. In my case it was green with algae. If the carpet/trim is bone dry then the roof seal aint leaking.

Although. Grey cells working. Now I remember quite a few years ago. I found a drip into my boot.

Poring water slowly near where the wing is close to the rear deck (blue arrows) water would run forward and around under the rear deck and find it's way into the boot. Dripping in at yellow arrow and pooling in the corner at red arrow.

There's panels spot welded together there and I decided that water was just creeping between the panels. I brushed on some good seam sealer over the panel joins around yellow arrow and problem went away.

My Navy roof was fitted at the Soft Top shop in Stockport 5 or 6 years ago and still looks brand new with no leaks.

Can you draw an arrow or arrows to show us where, please?

I stand corrected. Thanks for these photos and the explanation.

Nope. I can dismantle a Z3 for you but drawing arrows on a digital photo is way too difficult. :oops:
