Removing dents from a metal roof can be challenging and should be handled with care to avoid further damage. The repair method depends on the dent's size and location, as well as the type of metal roofing. Minor dents might be repairable using specialized tools to gently push the dent out from the underside of the panel. However, larger or more complex dents may require replacing the affected panel. It's highly recommended to consult with a professional metal roof repair contractor to assess the damage and determine the best course of action.
