A roofing nail is used in the installation of roof shingles and other roofing materials. It is typically a short, large-headed nail that is designed to securely attach roofing materials to the roof deck or other substrate. Roofing nails may be made of various materials, including galvanized steel, stainless steel, copper, or aluminum, and may have a smooth or threaded shank. Some types of roofing nails also have a rubber or plastic washer or cap that provides additional weather resistance and helps to prevent leaks.
