Which material is commonly used as a protective barrier on roofing?

• A. Plywood
• B. Tar paper
• C. Bamboo sheathing
• D. Clay tiles

Answer: (B)

Tar paper, also known as roofing felt, serves as a critical protective barrier in roofing applications. It is typically made from a base material like fiberglass or organic felt, which is coated with asphalt. This composition makes it highly effective for preventing water infiltration, protecting the roofing structure from moisture that can lead to mold, rot, and other forms of water damage. When installed before the roofing material, tar paper acts as a secondary line of defense against leaks, especially in areas where water might accumulate or where the roof is prone to wear and damage. Additionally, its installation is standard practice in roofing to enhance the overall durability and resilience of the roofing system. In contrast, while plywood serves as a structural component for roof decking, bamboo sheathing is not a common choice in traditional roofing applications, and clay tiles, although used as a primary roofing material, do not function as a protective barrier beneath them. Consequently, tar paper's specific properties and usage in roofing systems make it the correct answer.
