The industry shifted away from old multi ply built up systems toward single ply options like TPO and EPDM. TPO now dominates over 37% of the commercial membrane market driven by its heat reflective properties and seam strength. Seeing high energy bills force building owners to evaluate roof albedo scores has become standard practice. High reflective membranes drastically lower summer cooling loads which matters for facilities running continuous machinery. EPDM remains a reliable choice for cold climates because it handles heavy freeze thaw expansion cycles without cracking. However improper seam detailing often leads to premature failures when installers rush jobs. Industrial facility managers are discovering that material selection is only half the battle; the actual skill behind attachment methods decides whether a deck survives high wind uplift.
