Which of the following methods of installation is not allowed under Testing Applications Standard (TAS) 106?

1. Clips

2. Adhesive application

3. Cement bonding

4. Screw fastening

The correct answer is: Clips

The installation method described as clips is not allowed under the Testing Applications Standard (TAS) 106 because this standard emphasizes specific performance criteria for water management in roofing systems, particularly to ensure durability and weather resistance. Clips can introduce vulnerabilities in the installation's integrity, as they may not provide a continuous or secure connection compared to other methods like adhesive application, cement bonding, or screw fastening. These other options typically facilitate a stronger and more reliable attachment to the substrate, thereby ensuring better performance under the stress of environmental conditions. Adhering to standards like TAS 106 is crucial for maintaining the quality and functionality of roof installations, which must withstand wind and rain while minimizing the risk of water infiltration.
