First, identify the damaged area, which could be a rust hole, puncture, or seam gap. Clean the surface thoroughly with a wire brush and soapy water to remove dirt, rust, or loose debris. For small holes and cracks, use a quality metal roof sealant or roofing cement. For larger damages, cut a patch from a sheet of galvanized metal, making it at least two inches larger than the damaged spot on all sides. Secure it with roofing screws and apply sealant around the perimeter, ensuring a watertight fit. Finally, touch up with weather-resistant paint to match your roof and offer additional protection.
