Roofing felts are commonly made from fiberglass because it offers several beneficial properties that make it suitable for use in roofing applications. Fiberglass is known for its durability, resistance to moisture, and dimensional stability, which helps the roofing felt maintain its shape and effectiveness over time. Its ability to withstand temperature fluctuations and exposure to UV rays also contributes to the longevity of the roofing system.

While other materials like polyester and wood pulp can be used for various applications, they do not have the same level of performance characteristics that fiberglass provides in roofing felts. Plastic, on the other hand, is typically not used as the primary material for roofing felts, as it does not possess the necessary qualities to effectively protect and insulate a roof when used as a base material.
