A foam roofing underlayment is provided with a reinforcement membrane having an array of fastener elements for engaging fastener elements on a flexible roof membrane. The underlayment is formed by molding foam between the reinforcement membrane and a carrier membrane. The underlayment in secured to the roof using washers having fastener elements for engaging the fastener elements of the flexible roof membrane. An anti-peel flap with fastener elements is provided around the periphery of the washers. A slip sheet is used between the underlayment and the flexible roof membrane to permit accurate positioning of the flexible roof membrane prior to engagement of the fastener elements. The interstices between the fastener elements provide lateral moisture paths to vents in the flexible roof membrane.

The present disclosure provides embodiments of a releasable fastening arrangement that can include a first fastening strip secured to and extending over a substrate surface and having a first surface carrying first fastening elements extending from the surface. The releasable fastening arrangement can also include a second fastening strip having a second surface carrying second fastening elements that are engageable by the first fastening elements to form a releasable fastening. The first surface can include a flexible flap that is formed therein, and that is surrounded by other portions of the first surface. The flap can carry at least one of the first fastening elements, and can flap have a distal edge that is displaceable from the substrate surface under peel loads applied to the at least one first fastening element carried by the flap.
