The answer
Asphalt Shingles: lowest upfront cost ($350–$800/sq installed), 15–30 yr lifespan, vulnerable to wind/hail. Metal Roofing (Standing Seam): high durability ($800–$1,600/sq), 40–70 yr lifespan, 140+ mph wind rating, Class A fire rating, reflective cool-roof coatings lower attic heat 10%-25%. Concrete/Clay Tile: extreme lifespan ($800–$1,800+/sq), 50–100+ yrs, but very heavy (600–1,100+ lbs/sq) requiring structural truss engineering.
