30 Century S Roof Question

[Guest Dvernon372]

Hi Everyone. Continuing work on my 30 Century S restoration and have a question about the thin strips that nail on the roof around the edge and around the soft part of roof. It looks like they are a 2 inch wide strip of metal that was folded on itself after it was nailed in place. My question is how to unfold it to replace the nails without making it look like I opened it with a old fashioned can opener? I would appreciate suggestions from you guys that have experience with this. Thanks.
