Steep Slope Roofing Systems Steep slope roofing usually refers to roofing materials suitable for roofs that have slopes of 3:12 or greater. This means for every 12 horizontal inches, the roof’s rise is 3 inches or greater. Materials suitable for steep slope roofing include asphalt roll roofing as well as asphalt shingles, concrete and clay tiles, wood shakes, slate and metal roofs.
