Probably depends on the builder. If it's just a molded roof section, then it's probably lighter but this particular one is taller than normal, it has a metal structure for additional strength, and it has an inner molded roof liner. I'd guess roughly 300 additional pounds, but the original metal roof and ribs are gone so deduct that. Maybe 150 pounds net gain? Just a guess.
Don't know if I'll be removing the liner from mine but I did find a photo of an FGME interior with the liner removed, a photo that I posted earlier. You can see the square tube structure. This pic was found on Pinterest and this van has the taller side doors with normal height rear doors, the reverse of mine.
