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
