Abstract
A sheet metal nail of the type for securing built-up roofing membranes used to waterproof cementitious roof decks has a head and a hollow shank portion integral therewith and designed to resist withdrawal of the nail from the deck in a conventional manner, the head however being of larger diameter than the head of the conventional nail used for this purpose and further having a design which allows the fluid asphalt conventionally poured over the nail during construction of the roofing membrane to bond the portion of the membrane beneath the head and thereby increase the wind uplift resistance of the roofing membrane. The nail is preferably of 'one piece' construction formed from a sheet metal blank.
