    Several factors influence the choice between TPO and modified bitumen roofing in asphalt or bitumen modification systems. Key considerations include climate, with TPO performing better in warmer regions due to its UV resistance, while modified bitumen offers superior flexibility in colder temperatures. Installation methods also differ; TPO is typically mechanically attached or fully adhered, whereas modified bitumen is often torch-applied or self-adhered. Additionally, cost, longevity, and maintenance requirements play significant roles in the decision-making process.
