Pros and Cons of Flat Roofing Systems
Flat roofing is not actually flat; it has a very low slope—between 1/4 to 1/2 inch per foot—so that it drains water. But such a low slope holds snow and water much longer than a steeply pitched roof and therefore needs a very different material to stay watertight. While standard sloped roofs typically have shingles that are overlapped like fish scales so that water slides over them, a flat roof is designed as a continuous, or monolithic, surface that can hold some standing water for a limited time.
