What materials are typically used for a bituminous roof?

Bituminous roofing typically utilizes felts, which are made from fibers or organic materials soaked in asphalt, along with small aggregates or minerals to provide protection and enhance durability. The combination of these materials creates a robust, waterproof barrier that is essential for roofing applications.

Felts are laid in multiple layers with asphalt, and the small minerals can help to protect the roofing surface from UV degradation, improve its overall strength, and add aesthetic appeal. This type of roofing is known for its cost-effectiveness and ease of installation, making it a popular choice among roofing materials.

Other options, while related to roofing and other applications, do not represent the typical materials used specifically in bituminous roofing. Paving slabs, thermoset rubber polymers, and polyvinyl chloride (PVC) films serve different purposes and are used in different types of roofing systems.
