Abstract
An insulative roof structure for application to a roof deck comprises a rigid foam panel having an upper surface and a longitudinal groove opening onto said upper surface. A rigid elongated strip having an upper surface is positioned within the groove with the strip upper surface being generally flush with the panel upper surface. A kraft board lamina including barrier means is bonded to the panel upper surface. A mechanical fastener extends through the lamina, the strip, the panel and into the deck for retaining the panel against the roof deck. A weather resistant membrane is adhesively bonded to the lamina.
