BACKGROUND: The Evergreen Speedway Grandstands are situated within the Evergreen State Fairgrounds in Monroe and were constructed around 1967. The building spans an approximate area of 30,000 square feet, encompassing a grade-level display and concessions area below bleachers. The grandstand roof, measuring approximately 15,500 square feet, covers the upper sections of the bleachers. The roof is a simple shed configuration, sloping from East to West at an approximate 2.5:12 slope. The roof panels are comprised of 22-gauge metal roof panels, each 38.5" wide and 21' long. The panels are fastened with gasketed screws to the top flutes of purlins, - spaced approximately 5'-2". The purlins also bear lights affixed at their ends and through the roof, In 2014, a comprehensive Roof Evaluation Report highlighted various issues with the roof's structure.

Inspection revealed the presence of water within the bottom flanges of select purlins, attributed to the purlins' design collecting condensation water due to an upturned edge.
