In 2015, the Placer County Water Agency took on a tear-off roofing project, in which SOPREMA products were used. SOPREMA was the right choice for this project because the breadth of products met the designer’s needs, including meeting California Title 24 energy efficiency standards with the use of ENERGY STAR® rated SOPRASTAR® Flam. Another appealing aspect was the versatility of SENTINEL® P150, which allowed coverage for the vertical walls throughout the roofing system.
