When to Choose TPO
- New construction or complete re-roofing projects
- Commercial buildings where energy efficiency matters
- Properties in high UV exposure areas
- Long-term investment with lower lifecycle cost
- Environmentally conscious property owners
When to Keep/Repair Butynol
- Existing Butynol roof in reasonable condition
- Budget constraints requiring lower upfront cost
- Small repair jobs rather than full replacement
- Roof that can be rejuvenated with liquid membrane overlay
- Properties where matching existing Butynol is preferred
Our Recommendation
For new flat roof installations or complete replacements, TPO is generally the better long-term investment. Its superior durability, energy efficiency, and environmental benefits justify the higher initial cost.
For existing Butynol roofs that aren't ready for full replacement, we often recommend liquid membrane overlay as a cost-effective solution that extends roof life by 10-15 years at a fraction of replacement cost.
