A hook and loop system for attaching a roofing membrane into the top of a building insulation board including a roofing membrane with a fleece backing having a release sheet on the fleece backing. The release sheet is manually removed in the field to attach the fleece backing directly onto a layer of hooks that have been pre-attached onto the top of the insulation board. The release layer may be somewhat sticky, yet not adhere too tightly to the fleece layer such that its removal does not damage the fleece backing. The release layer may also be pre-rolled together with the fleece backed roofing membrane and shipped together as a unit into the field.

A thermoplastic membrane composite comprising (i) a planar thermoplastic body having first and second opposed planar surfaces; (ii) a fabric backing fixedly attached to said first planar surface thereby forming an interface between said thermoplastic body and said fabric backing; and (iii) expandable graphite disposed at or near the interface.

The present disclosure relates generally to roofing structures, for example, suitable for covering houses and other structures. The present disclosure relates more particularly to a roofing structure including a decking layer, a base layer, a cap layer, and a plurality of rails disposed over the cap layer. The base layer includes a plurality of strips that form seams including a first base layer seam. The cap layer also includes a plurality of strips that form seams including a first cap layer seam that is spaced from the first base layer seam. The rails include a first rail that is aligned with the first base layer seam and a second rail that is aligned with the first cap layer seam.

Provided are roofing membranes comprising pressure-sensitive adhesives particularly adapted for use at cold temperature, and methods for using same. In one aspect, the disclosure provides a roofing membrane comprising: a bituminous sheet having a lower bituminous surface and an upper bituminous surface; and a non-bituminous cold-temperature pressure-sensitive adhesive disposed on the lower bituminous surface, the upper bituminous surface, or both, wherein the cold-temperature pressure-sensitive adhesive has an average adhesion of at least 10 lbs/ft (146 N/m) at 2° C. as measured by a two hour T-peel test.
