EPDM
A membrane that is superior to others in flexibility, elongation, uv resistance, and hail damage resistance. On average, a building in the United States consumes almost 5 times more energy in heating than in cooling according to a study published in the Journal of Climate.Dark colored EPDM is most common and saves on heating costs. Though it can be found in white which saves on cooling costs. EPDM comes in 45, 60, and 90 mil thicknesses.
