Project Profile

The former home to the Portland Trailblazers, Winterhawks and Timbers, Veteran’s Memorial Coliseum is arguably the city’s most significant example of mid-century architecture. Designed by Skidmore, Owings & Merrill and opened to public in 1960, it holds its rightful place on the National Register of Historic Places. The International Style glass and concrete building is sited to deliver a 360 degree view on the City of Roses. Today, it remains the senior structure within Portland’s Rose Quarter sports complex.

Protecting a jewel from the mad man era.
Preserving 140,000 sq. ft. of historic roofing is not to be taken lightly. Depending on who is telling the story, Memorial Coliseum is either an treasured cultural icon or a barrier to modern development. Either way, structures on the National Register of Historic Places require special care and attention to detail in their preservation. For the Granular Cap Sheet roof, Snyder estimator Richard Schleis recommended the reflective Energy Star-compliant system Karnak (298 Alumin-R) for the areas of poor drainage followed by Karnak’s SBS copolymer modified, asphalt-aluminum, reflective coating to further shield harmful UV rays and provide protection from areas where water tended to pool.
