1. What Is TPO Roofing?
TPO roofing is a single-ply roofing membrane made of a blend of polypropylene and ethylene-propylene rubber. It is designed to provide strong resistance against UV rays, heat, and chemical exposure. TPO is commonly used for commercial buildings but has also gained traction in the residential roofing market due to its excellent performance and affordability.
Key Features:
- Highly reflective surface for energy efficiency
- Flexible and resistant to weather changes
- Heat-welded seams for strong protection against leaks
- Available in white, grey, and tan colors
2. Benefits of TPO Roofing
