Abstract
A non-penetrating mechanical fastener for securing a flexible sheet of an elastomeric material to the upper surface of a roof via the use of a plurality of such fasteners, each of which includes upper and lower members, wherein the latter are anchored to the roofing surface. The upper member includes a snap-ring which clamps the sheet within an annular boss formed on the lower member and a locking cap which is engaged by an interference fit with the snap-ring to lock the ring in position within the boss. A method for securing the flexible sheet to the roofing substrate also is presented.
