To cut steel roofing, use an angle grinder, circular saw, or tin snips. Make sure to wear protective gloves and goggles, and always cut along the marked line to prevent jagged edges.

Steel roofing can be cut using various tools, including an angle grinder, circular saw with a metal-cutting blade, or tin snips for shorter cuts. When cutting, make sure to use protective gear, such as gloves and goggles, to avoid injury. It's important to cut slowly and steadily to avoid creating jagged edges, which can make installation more difficult. Always measure twice to ensure accuracy before cutting.
