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

116 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?

Tiles are easier to mass produce to work with any roof cheaply.

And I imagine any material durable enough for single-piece roofing could warp/expand/contract in the heat/cold which could damage or dislodge it over time.
