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

624 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?

In my country we use both tiled and sheet roofing. Long run metal sheet roofing is still installed in sections though as each roof truss design is individual so you need to be able to cut the sheets to the custom shape. Rigid (heavy) tiled roofing is less desirable for us now due to the local earthquake risk.
