TPO Roofing

TPO Roofing for Commercial Buildings

TPO (Thermoplastic Polyolefin) is one of the most common low-slope commercial roofing systems used today. When installed and detailed correctly, TPO can provide strong performance, energy efficiency, and durability. At Inspector Roofing and Restoration, we approach TPO roofing with a documentation-first mindset: inspect the system properly, identify the real failure points, and recommend the least disruptive solution that protects your building long-term.

What matters most with TPO:
TPO success is usually decided at the seams, penetrations, edges, and drainage — not the big open field of membrane. That’s why professional inspection and detail work matter more than “cheap squares.”

TPO Roofing Services We Provide

TPO Roof Inspections

Documented inspections of seams, flashing, penetrations, drains, ponding areas, and rooftop traffic zones.

TPO Leak Repair

Targeted repairs focused on the true water path—often seams, curbs, terminations, and transition points.

TPO Replacement Planning

When replacement is necessary, we help scope the right system plan based on building use, drainage, and risk.

Storm Damage & Claims Support

When storm damage is present, we document findings and support the process (coverage decisions are made by the carrier).

Common TPO Problems We Look For

  • Seam issues: poor welds, separation, stress points, or age-related weakness.
  • Flashing & penetrations: failures at curbs, pipes, conduits, and rooftop equipment.
  • Edge termination problems: unsecured edges can lift under wind and start progressive failures.
  • Ponding water: chronic pooling that accelerates membrane wear and increases leak risk.
  • Foot traffic punctures: damage around HVAC service paths without walk-pad protection.

⚠️ TPO Roofing Warnings for Property Owners

  • Be cautious of contractors who diagnose TPO issues without showing photos of seams, penetrations, and drains.
  • Avoid “coat everything” recommendations without explaining the failure points and drainage behavior.
  • No contractor can guarantee insurance approval for commercial roof claims.

TPO Roofing FAQ

How long does a TPO roof last?
Life expectancy depends on installation quality, seam/detail workmanship, drainage performance, roof traffic, and maintenance. A well-installed and maintained TPO roof can provide many years of service. The best first step is an inspection to evaluate current condition and risk areas.
Is TPO better than modified bitumen?
“Better” depends on your building. TPO can be excellent for reflective performance and welded seams. Modified bitumen can be strong for durability and puncture resistance. The right choice depends on roof traffic, penetrations, drainage, and long-term maintenance expectations.
What causes most TPO leaks?
Most TPO leaks are detail-related: seam failures, flashing issues at penetrations/curbs, edge termination problems, and drainage/ponding stress. That’s why documentation and targeted repair planning matter.
Can a TPO roof be repaired instead of replaced?
Often yes—if issues are isolated and the system is otherwise stable. Repairs can be very effective when the failure points are identified correctly. Replacement becomes more likely when problems are widespread or the system is at end-of-life.
Do you provide documentation for insurance claims?
Yes, when storm damage is present we provide inspection documentation and photos to support a clear evaluation. Coverage decisions are made by the carrier, but accurate documentation helps prevent missed scope items.
