Flat Roofing the Modern Way
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.Flat roofs are an aesthetically interesting and energy-efficient alternative to traditional sloped roofs. Flat roofs are generally versatile, easier to maintain, and more energy-efficient than most sloped roofs, so new home builders, in particular, enjoy the lower cost of long-term ownership.

Thermoplastic polyolefin (TPO) is the fastest-growing segment of the commercial roofing industry. TPO membranes are ENERGY STAR®-qualified, and Cool Roof Rating Council (CRRC)-certified and have been directly attributed to a reduction in energy use and cooling costs for buildings in warm, southern climates.
