The even distribution of weight across a roof joist network is intended to prevent the roof from collapsing.
Since the weight of a roof is fairly static it is easy to design for but engineers do need to think about issues like the accumulation of snow in cold climates layers of roofing materials added over the lifetime of the structure and changes in roofing materials when they determine.
