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

112 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?

Not a terrible idea. That said I think you would have to make the sheets on site then set them in place. I’m picturing warehouses with poured concrete walls that then get tilted up.
I’m thinking you would make a custom form on the roof then move it to the ground and pour your sheets. Then crane the final product back up to the roof.
The down side is it would have to be much thicker and stronger than concrete roof tiles to keep from cracking when moving it.
