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

638 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?

My house has a steel roof and instead of tiles it’s long sheets of metal that overlap horizontally. Doing it as one single sheet would make it much more difficult to manufacture, transport, and install.
