Flat roof - do they have to be flat?

I have the opportunity to rebuilt an area of flat roof on my house, with a slight slope. My question is, do flat roofs have to be flat? If not, why aren't they more often built with a little bit of a slope (intuitively that would seem to be helpful to get water off it). I live in a wet state (ie rain is the issue not baking sun). Thanks
