<p>A composite roof structure having two strata is supported by a roof substrate (3), which may be either a deck of a new roof or may be a previous roof. The stratum directly atop the roof substrate (3) is foamed-in-place insulation (8), with a lower surface thereof directly adhered to the roof substrate (3). The second stratum is a roofing membrane (5) having a bottom and a top surface, the bottom surface adhered to the upper surface of the insulation (8) by a pressure sensitive adhesive (1) initially disposed on the bottom surface of the membrane (5).</p> |
