Isn't it some sort of fibreglass ?

Fibreglass filler or glass fibre sheets and resin may make a repair

There may be a bottom plastic 'lining' (white), and then the top part (black). One or both may be fibreglass or plastic, either way they are probably brittle. I would opt for the white one being plastic and the top one some kind of fibreglass, although they may have changed the specifications. They may have been glued / bonded together to form the 'roof'.

I seem to remember that the roof was ABS, but susupect that, if it's like my 995's roof, it will be too far gone to patch with ABS solvent. I did manage a temporary repair with ally sheets pop-riveted "inside" the black bit, but eventually bought a new outer bit (in fibre-glass) from an Irish forum member (who doesn't seem to post here now) but needed the help of a second Irish ex-forum member to get it over here!

When I fitted the inner to the outer, I used some fibreglass to repair part of the inner and, so far, it has held up reasonably well - the trick is to make a good key in the original plastic, almost to the point of making holes through for the resin to grip. I did try repairing a bit of the gutter that had broken off - and that fell off more or less straight away!

Photos of the new roof (and, if you look closely at some of the pics, the damaged roof too) are here:

There are also pics of the damaged roof in the "Digger" album.

answer: cost.

It would take a lot of time, research and funds to get them into production and the amount of people prepared to pay several hundred pounds may not be high enough to justify the risk.

After a look back to the posts I did when doing my cab roof, Neville Porter was the man who supplied it:

He used to come on this site quite often, but a DB site started in Ireland and I think he goes there now (more customers there!!)
