Copper Rawlings Senior Center roof replacement

The existing roof consisted of an older built-up roofing system over a gypsum deck. Because of the existing deck, Core used a fully adhered replacement assembly with OlyBond adhesive rather than a conventional mechanically attached roof. This approach reduced reliance on fastening into the existing gypsum substrate.

The new assembly incorporated two layers of polyiso insulation, 1/2-inch DensDeck roof board, and a 60-mil fleeceback TPO membrane. Polyiso helps limit heat transfer through the roof, while a two-layer layout allows insulation joints to be offset to reduce gaps through the assembly. DensDeck adds a rigid protective layer that helps resist impact and damage from maintenance traffic.

The fleece backing adds reinforcement beneath the TPO and helps improve puncture resistance. The membrane was fully adhered with OlyBond, creating the new roof's weatherproofing surface.

The project also included new drainage and tapered insulation. Tapered insulation introduces slope into the roof assembly, helping direct water toward drainage points and reduce areas where water can collect.

Rooftop units and gas lines were raised as part of the work to accommodate the new roof assembly and provide access for roofing and flashing around equipment and penetrations.

From the gypsum deck to the drainage layout, this project reflects Core's approach to commercial reroofing: address the full system and the details that support long-term performance.
