Perimeter fastening for tile roofing areas from either side of the hips or ridges and edges of eaves and gable rakes include how many tile courses or not less than how many inches?

Perimeter fastening for tile roofing areas from either side of the hips or ridges and edges of eaves and gable rakes include how many tile courses or not less than how many inches?

• A. Two courses or 24 inches
• B. Three courses or 36 inches
• C. Four courses or 42 inches
• D. Five courses or 60 inches

Answer: (B)

The correct answer indicates that perimeter fastening for tile roofing requires a minimum of three courses or at least 36 inches. This specification ensures that the tiles are adequately secured at the vulnerable areas such as hips, ridges, eaves, and gable rakes, which are critical points for wind uplift and water intrusion. Using three courses provides enhanced stability and support compared to fewer courses, as each additional course distributes weight and helps prevent movement. This is particularly important in conditions where roofing tiles are subjected to strong winds or heavy rainfall. The 36-inch measurement represents a standard threshold that helps maintain the integrity of the roofing system throughout the lifespan of the installation. The other options suggest either fewer courses or lengths that do not meet common industry standards for securing tiles. The specification for three courses aligns with best practices in roofing installation to enhance durability and performance.
