Abstract: A method of inspecting canopy structures is provided to determine the structural integrity of the roof support system. The method includes steps designed to uncover hidden deficiencies in the roof support system through nondestructive testing and discovery. Timely use of the method of inspection not only minimizes the risk of canopy collapse but also produces information needed for making repair or replacement of the roof support system.

Abstract: A set of tools is provided for inspecting and obtaining critical data concerning the support structure of a canopy on support columns. The data obtained is entered into a computer programmed to generate a structure integrity report based on the data. The tools include a measurement wheel, an electronic level, a digital camera, a laser distance meter, an ultrasonic thickness gauge and optionally, a ladder and a drill. The computer can be local to the inspection or remote, and, if the latter, in communication with a personal digital assistant with wireless telephone capability into which the user can enter data.
