About Roofing Trade Coordination
Roofing rarely touches concrete directly, but it touches the building envelope we're already responsible for on tilt-wall and structural work: parapet wall height and flashing details, roof curb locations for rooftop mechanical units, and tie-in points at loading dock canopies and entry overhangs. We do not self-perform roofing work — that stays with a licensed roofing contractor — but on projects where we're delivering the tilt-wall panels, structural concrete, or full site package, we coordinate the roofing trade so the building envelope comes together as one sequence instead of two disconnected schedules.
Tilt-wall construction is where this shows up most in Allen and Collin County's warehouse and industrial market. Parapet height, coping details, and roof drain scupper locations all need to be set correctly in the tilt-wall panel design before the panels are cast, because those details are extremely difficult and expensive to modify once the panels are standing. We work from the roofing manufacturer's flashing and termination details during panel design so the roofer isn't fighting the concrete after the building is dried in.
On new warehouse and distribution center construction, we also coordinate roof curb placement for rooftop mechanical units with both the roofing contractor and the HVAC trade, since a curb set in the wrong location or without proper structural support underneath causes problems for both trades later. For projects where we're not delivering the full structural package but a client needs a roofing subcontractor sourced and held accountable as part of a broader trade coordination request, we can manage that relationship the same way we manage HVAC and MEP sourcing.
This coordination role matters most on tight-schedule industrial and warehouse projects, where a building isn't watertight — and downstream trades like electrical, drywall, and equipment installation can't proceed — until roofing is complete. We sequence roofing into the overall project timeline from the start rather than treating it as an independent trade that shows up whenever it shows up.

Frequently Asked Questions
Do you install roofing systems yourselves?
No. We do not self-perform roofing work, which requires a licensed roofing contractor. On projects where we're delivering the structural or tilt-wall concrete, we coordinate the roofing trade so parapet, flashing, and curb details align with the concrete, and we can source and manage a roofing subcontractor as part of a broader trade coordination scope.
Why does parapet wall design matter for roofing on tilt-wall buildings?
Parapet height, coping, and scupper locations need to match the roofing manufacturer's flashing and termination details before the tilt-wall panels are cast. These details are difficult and expensive to change once the panels are standing, so we coordinate with the roofing spec during panel design.
Can you coordinate roof curb placement for rooftop HVAC units?
Yes. We coordinate roof curb locations with both the roofing contractor and the HVAC trade to make sure curbs are structurally supported and positioned correctly before mechanical equipment is set.
Do you offer roofing trade coordination without a concrete project attached?
In most cases our roofing coordination is tied to a tilt-wall or structural concrete project we're already delivering. For property owners who need a roofing subcontractor sourced and held accountable as a standalone request, contact us to discuss the scope.
Why does roofing sequencing matter for the overall project schedule?
A building isn't watertight until roofing is complete, and several downstream trades — electrical, drywall, equipment installation — can't proceed until it is. We sequence roofing into the project timeline from the start so it doesn't become the item that stalls the schedule.
