ELI5: Why do malls and businesses not have peaked roofs like you see on houses?

I remember hearing about a store collapsing from too much snow collecting on the roof. Is there a reason not to have a peaked roof to prevent this?

Flat roofing is cheaper to build, is accessible (you can go up on it and do stuff up there more easily, including maintenance and are unlikely to fall), and you can add another floor more easily if you want to.

Providing you have a decent membrane on there and it doesn't need much maintenance, it will be cheaper in the longer run than a pitched roof, and gives you more options.
