Roofing scope on a tilt-wall or PEMB building depends entirely on what happens below it. Wall panel erection sequencing, structural steel tolerances, and the parapet and ledger details we cast into our concrete all determine when a roofing crew can safely mobilize and how their deck attachment will actually perform. We coordinate roofing subcontractor scopes on the industrial and commercial buildings where we self-perform the tilt-wall and structural concrete, keeping the transition from our scope to the roofing trade's scope from becoming a schedule gap.
That coordination starts at the design stage, reviewing parapet height, ledger angle embed locations, and roof drain leader locations against the roofing manufacturer's system requirements before we finalize tilt-wall panel forms. A parapet cast an inch off the roofing system's specified height, or a ledger angle missing an embed the roofer needs for deck attachment, turns into a field modification that costs real money and real schedule once steel and panels are already up. We catch that at the concrete design stage instead.
Once panels are erected and steel is topped out, we sequence the handoff to the roofing crew directly with the general contractor's schedule, flagging weather windows relevant to Collin County's spring storm season, when hail and high wind can shut down a roofing mobilization for days at a time. Buildings going up around The Star, Frisco Station, and the industrial parks along the Tollway are frequently racing a tenant delivery date, and a roofing delay that was avoidable at the design stage is the kind of miss that shows up in a developer's carrying costs.
We do not install roofing systems. What we manage is the concrete-side design and sequencing that determines whether a roofing crew mobilizes on schedule with a deck that actually matches their system's requirements, backed by roofing subcontractor relationships across multiple North Texas industrial projects.
