if i lived in a hurricane area and had a pitched roof, i'd go with cedar shingles if i could find CCA old-growth ($500+ per square these days), toe-nailed with 2" staples and cap on the rake-edges, or a tri-lam composition shingle like Landmark TL or Presidential TL, and do 6 nails per. otherwise, coated concrete on a flat roof will never blow off.
