Which brand is NOT a type of single ply membrane roof?

Goodyear is not known for manufacturing single ply membrane roofing products. The other brands listed—Firestone, Johns Manville, and Carlisle—are well-recognized as leaders in the single ply roofing market, known for their various membrane products such as TPO, EPDM, and PVC. Each of these companies offers a range of roofing solutions specifically designed for commercial and industrial applications, focusing on durability, weather resistance, and ease of installation. Goodyear, on the other hand, primarily focuses on tires and rubber products, and while it has a history in various industrial applications, it does not produce roofing membranes in the same context as the other brands listed.
