Why do we need roofs on houses? Why can’t we just build it flat on the top?
In: 0
Roofs need to shed precipitation. The shallower the angle of a roof, the less incentive rainwater has to flow off it, and the more time it has to wick its way underneath shingles or through seams. In areas that get below freezing, flat roofs can accumulate enough ice and snow to cave them in. The more snow an area gets, the steeper the roofs tend to be.
