A roofing system provides a stronger bond than conventional roof systems to withstand greater uplift pressures in hurricane force winds, while also providing a sound fire rating. The system includes a non-corrosive metal blocking structure, including a perimeter edge closure that has an anchoring flange for attachment to the roof deck, a parallel upper flange and an intermediate flange extending perpendicularly between the upper and lower flanges. The system further includes lightweight insulating concrete applied to the roof deck and filled between the upper and lower flanges of the edge closure, an inter-ply sheet applied by torch or self-adhesive directly to the insulating lightweight concrete, and a torch applied cap membrane over the inter-ply sheet. Direct attachment of the inter-ply sheet to the lightweight insulating concrete without the use of hardware fasteners preserves the integrity of the underlying lightweight insulating concrete for future re-roofing.
