A roofing nail is mainly used for installing roofing (sometimes for water resistant drywall,tile backer board etc). The main feature that distinguishes a roofing nail is its large head,galvanization appearance, which is usually much larger and flatter than other types of nails. This permits the nail to hold down roofing felt and roofing shingles without tearing through the material. Roofing nails generally come in lengths of 1 to 1.75 inches (2.54 to 4.44 cm), although shorter and longer nails can be found.
