Abstract
A single-ply roofing system is disclosed according to the teachings of the present invention as including a roof sheet for covering a roof of the desired construction. In the interior of the roof area, the roof sheet is held to the roof by battens fastened to the roof through the roof sheet. Batten sealing members are provided which will increase bonding strength over a period of time and which may thus be considered to undergo a self vulcanizing-like process with the roof sheet and encapsulate the batten between the roof sheet and the batten sealing member. The roof sheet is held on the roof adjacent the roof edge by edging members having a generally horizontal flange which extends from the roof edge and rests on the top surface of the roof sheet. The edging member is fastened by fasteners which extend through the flange, through the roof sheet, and into the roof. In the preferred embodiments, edging members of the gravel stop edge and gutter installation types are illustrated for explanation of the teachings of the present invention. Flange sealing members are further provided for sealing the flange of the edging members and the flange fasteners with the roof sheet.
