No it needed to be decked, it was true 1x but I asked him why they used 3/4 and he goes because it's stronger. 3/8 would have been fine by me. But the big problem was at the fascia it was 2.5" of decking.If too many boards need replacement, it's faster to deck right over the top. I'm guessing that's what was done, but 3/4 is a little stout for doing that. You can also get into an issue on some buildings that the old 1X is thicker than the new 1X, so getting boards to match can be a problem.
