Hey
@1604hutch
Ouch!
I will be able to tell you in a couple of weeks whether I've solved this. I am due to take the van to Vanmax for a replacement roof (yup, the whole shebang!)
A couple of questions - who did the work at the back? If it was HiLo themselves, then you might be stuck (given that they are in liquidation) - if they did this as warranty work (heaven forbid), then you might have a case to become a creditor (not that will do much). However, don't hold your breath for anyone to come to the rescue with the Surf roof even if they become a supplier of roofs that have an identical design to a company formerly known as HiLo - the Directors sold the assets just before they liquidated and out of the ashes comes All Things Custom Ltd. and the liquidation report doesn't even mention the debacle of the Surf roof!
If you paid someone else for this 'repair', I would recommend you 'insist' that this company repositions the hinges so that you can at least close your roof. I would guess that they would need to disconnect the gas struts, lower / position the roof flat on the van, connect the front bolts exactly central to the holes, and THEN tighten their bolts at the back. Then raise the roof and put the gas struts back on. This was a major reason that I decided not to try and fix the hinge - the tolerances are small and the knock-on effects are significant (sorry, I know I'm pointing out the obvious to you at this time, but this is for the benefit of other owners of Surf roofs!).
In my case the roof went squint at the front because the hinge had broken, so I got a long strap, wrapped it across the roof and pulled outwards until the front rods dropped in the holes - then got another person to tighten the bolts inside whilst I (literally) hung off the side of the van. I'm not sure that you'll be able to do that if the rear corner has been fixed in position.
I will let you know how things go with Vanmax - my discussions so far suggest that the existing cut-out should be fairly similar to that required for the new roof (I haven't yet found another manufacturer who can confirm the size / position of their cut out, possibly for commercial confidentiality reasons). I have made a deliberate decision to go direct to the manufacturer rather than a fitter, even though I have to take the van 380 miles each way and leave it with them for 2 weeks. If you can wait until mid October, I'll report back. I've got everything crossed (including my bank account) that this works.
Send me a direct message if you want any more information / discuss anything... I feel your pain, so if there's anything that you need to get off your chest, best done privately!
Good luck in the meantime.
