What is recommended for step flashing in wood shingle roofing systems according to NRCA?

A Exposure plus 5 inches
B Exposure plus 3 inches
C Exposure plus 10 inches
D Exposure plus 8 inches

The correct answer is: D Exposure plus 8 inches

The recommendation for step flashing in wood shingle roofing systems, according to the National Roofing Contractors Association (NRCA), is to use a measurement of exposure plus a specified length that ensures proper water management and protection against leaks. Using exposure plus 8 inches is aligned with best practices, providing sufficient overlap to direct water away from the roof structure effectively. This measurement helps to accommodate the natural movement and expansion of wood shingles, thereby safeguarding the underlying structures beneath the shingles. The other options either do not provide enough coverage or exceed the necessary length for effective installation, which could lead to inefficiencies in the flashing system. The goal is always to achieve adequate weatherproofing while maintaining practical installation standards, making 8 inches the most effective choice in this scenario.
