This slant is meant to keep water from pooling on top of the roof, causing damage, and then leaking into a home. When an ice dam forms, water can't run off the roof and into the gutters or on the ground. <br /> <br />This situation occurs when temperatures dip below freezing. Very often, ice forms on the lowest parts of a roof. This ice creates a sort of frozen wall on the roof that actually works like a dam. When water melts on the roof, it melts on the highest point first. This can actually create a flood on top of a normal slanted roof.
