What type of field testing is typically specified to verify all the components of an adhered system are installed properly and in a manner that they comply w/ the uplift requirements? |

The best way to verify the wind uplift requirements are met is for the owner to provide on-site observation during installation to make sure that it is done according to the shop drawings. Shop drawings should be based upon manufacturer's tested system. Once everything's covered up, there's no way to discern how many fasteners were used, or the size of the adhesive ribbons, for example. You can do destructive testing on a random basis, but now you have patches all over your brand new roof. |

John is correct about having patches all over your new roof. Instead, you could test mock-ups to determine what is required to meet the uplift requirements; then use on-site observation to ensure compliance with the accepted methods tested in the mock-up. |
