Concrete is used in places like Cuba, Puerto Rico, Dominican Republic, not sure why Florida insists on piece of shit houses with bricks and gypsum board inside, but the absolute classic, wooden rooves!
Houses here are made of CMU block, with poured concrete at window locations. A concrete roof is very expensive and I don't think from my visits to Cuba that they have concrete roofs. In a cat 4-5 that's all that matters is how much can the roof hold. everything else is noise.
