A roofing nail is a type of nail used for securing roofing materials like shingles or sheet metal to a roof. It typically has a short, thick body and a wide, flat head to hold materials firmly in place and prevent them from tearing. Roofing nails are often made of coated steel or other rust-resistant metals to withstand exposure to weather. They are designed to provide a strong hold and durability, making them essential for roofing work to ensure materials stay secure over time.
