GenFlex TPO Reinforced Outside Corners are precision factory-fabricated from high-performance TPO roofing membrane to ensure consistent quality and reliable performance. The large 12″ x 12″ (304.8 mm x 304.8 mm) design allows the flashing to easily conform to irregular outside corners or complex jobsite conditions. Factory welds simplify installation, reduce labor time, and enhance long-term watertight protection—helping ensure a clean, professional finish on every TPO roofing system.
