ABSTRACT:
An improved roofing nail having a cap which is held captive near the nail point for the purpose of attaching roofing felt to a wooden roof. The nail point extends slightly below the lower surface of the cap allowing the point of the nail to be manually engaged into the roofing felt. The cap positioned at the end of the nail provides support to hold the nail in an upright position until the nail is driven through the cap and into engagement with the roof substructure, after the hand of the user has been removed.
