What does a Plano warehouse TPO roof replacement actually involve start to finish?
Disclaimer: this is general guidance from a North Texas roofing contractor. Every roof is different — actual scope, cost, and timeline depend on an on-site inspection. Insurance specifics depend on your policy and carrier.
The Plano warehouse was a 1990s build with the original modified bitumen roof system. 42,000 square feet of flat roof, 30+ active leaks, and the building owner was burning through $35,000/year in repairs and patches. We replaced the system with TPO in fall 2025.
What we found on the initial walkthrough
Every commercial project starts with a walkthrough — and on this one, the walkthrough revealed:
- Active issues consistent with system age (failure points concentrated at penetrations, seams, and edge details)
- Underlying decking conditions that needed assessment before final scope
- Drainage and water management issues contributing to the wear pattern
- HVAC, electrical, and mechanical equipment that would need coordination during the work
- Operational constraints — how the building uses its hours and when work could feasibly happen
The walkthrough produced a 14-page condition report with photos and a written scope. This is what commercial roofing professional practice looks like — not a verbal estimate from a flatbed full of crew.
Scope and material decisions
commercial roofing in McKinney, TX decisions involve more variables than residential. For this project the conversation covered:
- Membrane type: TPO, PVC, EPDM, modified bitumen, or specialty coating — each with different cost, lifespan, and weathering profiles for North Texas conditions
- Insulation strategy: Rigid ISO board, EPS, or other — affects long-term thermal performance and energy cost
- Edge details and parapets: Where commercial roofs fail first
- Penetration handling: HVAC stacks, plumbing vents, electrical conduits — every one is a potential failure point
- Drainage: Internal drains, scuppers, gutters — adequate drainage is the single highest-impact lifespan factor
- Warranty structure: Manufacturer NDL vs. material-only, and what they actually cover
Cost and timeline
Commercial roofing costs in McKinney and the surrounding cities run dramatically wider than residential. Order of magnitude:
- Repair scope: $1,500-$25,000+ depending on extent and access
- Coating system: $3-$8 per square foot installed
- Full replacement (TPO/PVC): $7-$15+ per square foot installed
- Premium systems with specialty membranes: $15-$25+ per square foot
Timeline scales with square footage and system complexity. Small repairs are same-day or next-day. Mid-scale projects (5,000-20,000 sq ft) typically run 1-3 weeks of active work. Large replacements (50,000+ sq ft) can run 4-8 weeks or more depending on weather and access.
How operations get coordinated
The conversation no residential project has: how does the work happen without shutting down the business?
- Phased work zones so portions of the building stay operational
- After-hours scheduling for noise-sensitive operations
- Weekend-only work for office buildings
- Coordination with HVAC and electrical to handle disconnects
- Tenant communication for multi-tenant properties
- Insurance coordination for liability during the work period
This coordination is often more complex than the roofing scope itself. Getting it right separates contractors who do commercial work from contractors who claim they do commercial work.
