It's all about cost. Wood is cheap. It's quick to install. It's also strong, so you don't need a lot of material to make the building strong.
It's like drywall and fiberglass. There are a lot of materials out there, both for structure, insulation and finished surfaces that are fire proof water proof, and better for a lot of other things too. But get water or fire in a modern house, and you have to rebuild the thing.
That's the general problem with sprinklers. I don't see your roof sprinkler idea doing much. Too much area to try to keep from catching on fire. Sprinklers work on the inside, but then you have to replace the carpets and drywall.
