The answer to 'difference between TPO roofing and EPDM roofing' is that TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer) are two of the most popular types of commercial and residential flat or low-slope roofing materials. Both are durable, energy-efficient, and widely used, but they have some key differences in terms of composition, installation, and performance.
TPO is a single-ply membrane made from a blend of polypropylene and polyethylene. It is known for its reflective white surface that helps reduce cooling costs. TPO is generally less expensive to install than EPDM and is easier to repair. EPDM, on the other hand, is a synthetic rubber membrane that is black in color. It is more flexible and durable in extreme temperatures, making it a good choice for harsh climates. EPDM is also typically more expensive to install than TPO.
