A successful repair to that roof panel would almost certainly need the glass removing, and the roof fully painting, expect quotes to be around £500/600 plus VAT, don't forget that if you pay yourself, you also run the risk of having to pay out for a new screen should it break on removal, or re fitting!!
If you are fully comp insured, with protected NCB, and a reasonable excess to pay (ie, less than the above figure) then I would recommend claiming on your Insurance as your best, and cheapest option
