7.1.21. Design specifies a minimum 18-gauge metal gravel stop or fascia strips?

7.1.22. Flashed joints are located above the roof waterline, or, if that is impractical, flashings are kept out of low areas where ponding may occur?

7.1.23. Protected membrane roof (PMR) system design specified to enhance R&M (based on life-cycle costs)?
