Abstract of the Disclosure A fastener for securing built-up roofing membranes used to water- proof cementitious roof decks combines the conventional nail used for this pur- pose having a head and a shank portion designed to resist withdrawal of the fastener from the dock, with a non-intergral tab penetrated by the shank of the nail and of larger diameter than the nail head, the tab having a design which allows the flued asphalt conventionally poured over the nail during construction of the roofing membrane to bond the portion of the membrane beneath the tab and thereby increase the wind uplift resistance of the cover- ing material. Removability of the tab allows its detachment in applications where increased uplift resistance is unnecessary.
