Replacement Options
TPO (thermoplastic) roofing was developed in the mid-1990s as an improvement over rubber. And it is better - but it's still dealing with 30-year-old technology. The seams can fail, it gets brittle with age, and you're paying for yesterday's solution when modern options exist.
What You Get with TPO:
- Better performance than rubber, but still limited
- Heat-welded seams that can fail over time
- Membrane becomes brittle and cracks with age
- Moderate energy efficiency compared to newer options
- Decent lifespan with proper maintenance (20-25 years)
- Mid-range pricing for mid-range performance
Material Properties
- Thickness: 45-80 mil single-ply membrane
- Installation: Fully adhered, mechanically attached, or ballasted
- Seaming: Heat-welded (stronger than rubber tape, but still problematic)
- Temperature Range: -40°F to 250°F operating range
- Warranty: 15-25 years material (better than rubber)
- Energy Efficiency: Good reflectivity, moderate energy savings
Scenarios Where TPO Makes Sense:
- Budget upgrade from rubber - Want better performance without premium cost
- Mid-term facility planning - 15-20 year building ownership timeline
- Moderate climate conditions - Less extreme temperature cycling
- Basic performance needs - Standard warehouse or light manufacturing
- Existing TPO repairs - Matching current system for additions
Our Position: "TPO is the compromise choice - better than rubber, not as good as modern options. If you need something in the middle, we can make it work well."
TPO's Honest Drawbacks:
- Seam welding challenges - Quality depends heavily on installer skill
- Brittleness over time - Membrane flexibility decreases with age
- Chemical sensitivity - Some building chemicals can damage TPO
- Limited repair options - Damaged areas often require large patches
- Technology plateau - Hasn't improved significantly in 20 years
Why Spend a Little More:
Flexible Vinyl Blanket
Superior durability and appearance
Seamless Coatings
Modern technology with renewable characteristics
If TPO Fits Your Needs:
- Expert seam welding - Certified technicians ensure quality connections
- Proper membrane selection - Choose appropriate thickness and formulation
- Quality fastening - Mechanical attachment done to wind uplift requirements
- Realistic expectations - Clear communication about maintenance needs
- Ongoing support - Regular inspections to catch issues early
- Upgrade planning - Help you transition to better technology when time comes
