Whether you are a home- or business owner, keeping a roofing file is one of the best ways to ensure your roof’s long-term health and performance. It is a record of your roofing system’s condition, updated constantly to help you keep track of everything about your residential or commercial roof. You have to start building it the moment your roofing contractor replaces your old roof. Eventually, it will contain vital information, such as the results of roof inspections and repair work.
