Roofing Coordination

Tilt-wall and pre-engineered metal buildings live or die on the interface between the concrete structure and the roof system above it. Panel height tolerances, parapet details, and structural steel bearing points all have to match what the roofing subcontractor needs to install a system that won't leak at the first hard rain, and North Texas gets plenty of those. We coordinate roofing subcontractor scopes on the tilt-wall and PEMB projects we self-perform concrete for across Grapevine and the DFW Metroplex.

We don't put roofs on buildings ourselves. What we do is make sure the concrete and structural work underneath the roof — panel elevations, parapet cap details, structural steel bearing seats — is built to the tolerances a roofing subcontractor actually needs, and we bring in licensed roofing partners to execute the membrane or metal roof system itself. This matters more than it sounds like it should. A tilt-wall panel that's out of level by even half an inch at the parapet can create ponding issues or flashing problems that show up as a leak two years later, long after everyone's moved off the project.

Hail is the other reason this coordination matters in North Texas. The DFW Metroplex sees regular hail events, and TPO and metal roofing systems installed on our tilt-wall and PEMB projects need to be specified and installed correctly to hold up to it. We coordinate roofing material selection and installation sequencing with our building shell schedule so the roof goes on as soon as the structure is ready, minimizing the window where an open building sits exposed to weather.

Whether we're the concrete self-perform contractor on a project bidding to a general contractor, or working directly for a developer who wants one point of contact managing the shell-to-roof interface, we manage roofing coordination as part of the broader building delivery.

We've coordinated this interface on tilt-wall buildings from small flex-industrial spaces in the Mid-Cities to larger distribution shells near the Alliance corridor, and the lesson holds at every scale: a roofing subcontractor who's never seen the panel elevation survey is guessing at flashing details, and a guess is exactly what North Texas hail doesn't forgive. We share the actual as-built concrete tolerances with the roofing crew before they start, not only the design drawings.
