Retrofit roofing involves installing a TPO membrane over an existing roof, providing a cost-effective way to improve performance and extend lifespan without a full tear-off. It offers numerous benefits: durability, energy efficiency, lightweight design, easy installation, and resistance to UV rays, chemicals, and mold. TPO’s heat-welded seams enhance waterproofing, while its recyclability makes it eco-friendly. Ideal for commercial, industrial, and institutional buildings with flat or low-slope roofs, retrofitting is a practical solution for large areas and energy-conscious projects. However, assessing the current roof’s condition with a contractor is essential to ensure suitability.
