The concrete work and the roofing work on a commercial building meet in more places than most owners expect — parapet walls, roof curb blockouts, tilt-wall-to-roof deck connections, and the drainage and scupper concrete that determines whether a roof actually sheds water the way it is designed to. We coordinate that handoff with licensed roofing contractors so the sequence between our concrete crews and theirs does not cost a developer weeks of schedule.
On tilt-wall and precast buildings, panel height and parapet detailing have to match the roofing system's edge and flashing requirements, which means our panel layout has to account for the roofer's transition details before panels are cast, not after they are standing. On flatwork and site concrete, that means building drainage structures, scupper pads, and downspout splash blocks sized to the roof drainage calculations, so water leaving the roof has somewhere engineered to go instead of pooling against a building foundation.
We do not install roofing membrane ourselves — that work stays with a licensed roofing contractor — but we manage the concrete-side coordination and scheduling so a general contractor or developer has one point of contact tracking how the building envelope comes together, instead of chasing separate updates from the concrete crew and the roofer independently.
Rowlett and the wider Dallas County market see enough hail and wind events that roof drainage and edge detailing determine whether a roof warranty holds, well beyond the code minimums. We build drainage concrete to the specified slope and capacity, confirm scupper and downspout locations against the roofer's layout before we pour, and document the handoff so both the roofing warranty and the building's stormwater compliance hold up under inspection.
