What does NRCA recommend when installing a slate roof regarding fastening?

Use adhesive only
Use screws at every corner
Just touch the nail head to the slate
Use additional reinforcement plates

The correct answer is: Just touch the nail head to the slate

When installing a slate roof, the National Roofing Contractors Association (NRCA) emphasizes the importance of proper fastening techniques to ensure the longevity and effectiveness of the roof. The correct practice involves using appropriate fasteners to securely attach the slate while avoiding over-tightening that can cause damage. Using just a touch on the nail head does not provide the required support and can lead to slippage, leaks, and potential failure of the roofing system over time. Instead, NRCA recommends that nails should penetrate the slate and be securely fastened to the underlying structure while still allowing for some flexibility, as slate needs to expand and contract with temperature changes. The other options would not align with best practices: relying solely on adhesive does not provide the necessary mechanical fastening; using screws at every corner is not practical and can compromise the integrity of the slate; and relying on reinforcement plates is not a standard recommendation for slate installation. Each of these alternatives fails to balance secure fastening with the inherent characteristics of slate.
