ABSTRACT:
A method of making a flat, or nearly flat roof watertight by covering the roof with a sealing layer, particularly a polyvinyl chloride sheet, and securing the sheet to the underlying structure by a number of plates and screws or nails passing through the plates. To provide a watertight and durable joint between the polyvinyl sheet and the plate, a bonding agent is applied on the sheet on the intended points of securement of the plates, and a seal is provided between the screw or nail head and the plate.
