Why do we use tiles for roofs instead of a smooth flat sheet?

128 viewsOther

Why roof tiles exist. I understand why we don’t have flat roofs, but why do we have hundreds of tiles that sort of overlap each other and can be pulled or blown off easily?

Why aren’t roofs like a giant tent, still A shaped but each side is just a big sheet of whatever weatherproof material we got?

OP sheet metal roofs exist, my house and garage have metal roofs. They aren’t one piece but aren’t like tiles or shingles either. last a long time but they’re noisy when it rains. They’re also fireproof.
