Abstract
A roof scaffolding system includes a curved roof hook attached to a linear, metal membrane strip unit having connector rivets and nail holes. The metal strip includes double slot keyholes and attachment apertures that engage corresponding rivets on the roof hook. The opposite end of the metal strip includes connector rivets engaging double slot keyholes of an identical metal strip, extending opposite the roof hook. The nail holes allow attachment of wood spacers beneath the metal strips. Multiple strips are joined extending from the peak to the roof edge. A coupler connector covers the connection between joined metal strips preventing disconnection. Roof jacks include both nail slots and keyholes for attachment to the metal strips, as well as safety hooks for attachment of a lanyard from the scaffolding to workers. The roof jacks hold a plank that spans adjacent metal strips, the plank providing a place to stand.
