Project Profile

As the primary arena in the Portland area, The Rose Garden hosts the region’s largest indoor concert and sporting events and is home to the NBA Portland Trailblazers and the Portland Winterhawks of the Western Hockey League. Located near the Willamette River and Interstate 405, at 181,631 square feet, the iconic off-white, saddle-shaped roof is visible from most vantages in the city. Appearance is important. Cleanliness is king. In 2013, The Rose Garden was rechristened the Moda Center. No matter the name, it remains an iconic cultural hub.

A performance worth of attention.
Opened in 1995 with combined funds from the City of Portland, Microsoft billionaire Paul Allen, and $155 million in bonds, the precast concrete structure is capped with a steel skeleton and membrane roof. Heavy moisture during the course of many years had transformed the original white to a cloudy and dingy gray. Given the visibility of the unique roofline, the appearance was less than attractive and the membrane had collected considerable dirt, grime and growth. In addition to identifying minor repairs, it was in need of a good, old-fashioned hand cleaning. Snyder would furnish labor and materials to power wash (and scrub) the roof and ensure waste water was properly flushed.
