Project Description: Cascade Apartments Buildings 1 and 2 are placed conveniently in downtown Seattle right off of Mercer and Fairview. This modern development comes complete with rooftop gardens and patios to enjoy the outdoor space in beautiful Seattle. With garden top amenity and occupied space on the roof of the building, the roof system need to be tough and durable. The owners chose to install Soprema’s 2 ply SBS Modified Bitumen Roof System. The roof included Sopravap’r self adhered vapor barrier, R38 Rigid Insulation, ¼” Foot Slope Tapered Insulation, Sopraboard and a torch applied 2 ply Sopralene Flam system and Soprema Alsan RS PMMA liquid applied flashings. The walking deck required railing penetrations through the roof, including roof top units for air conditioning and screen walls, the final penetration count on both of these buildings is over 972!
