The roof does, yeah. At least for the next few hundred years.
They can't "rebuild" it anyway. They can replace it with something new.
I'm sure that over the years they have blueprinted the structure down to the last detail so that it can be reconstructed in exact detail. When tourists walk past, I'm sure they won't just turn up their noses and say "pff! Those aren't the original shingles!"
