What is the recommended minimum overlap on plain bevel siding?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 4 inches

Answer: (A)

The recommended minimum overlap on plain bevel siding is indeed 1 inch. This overlap is crucial for ensuring that water runs off the siding effectively and does not penetrate behind the boards, which could lead to water damage and mold growth. A 1-inch overlap allows for adequate drainage while maintaining the siding's structural integrity and aesthetic appearance. While larger overlaps, such as 2 inches, 3 inches, or 4 inches, may provide additional security against moisture intrusion, they often do not take into account the practical aspects of installation, such as the overall appearance and the potential for wasting material. A 1-inch overlap strikes a balance between functional performance and efficient installation, making it the standard recommendation in many building codes and construction best practices.
