Raymond Recreation Center
HRGM was contracted directly with DGS to remove the existing gym/multipurpose roof at Raymond ES and install a new White PVC roof and Architectural Decor PVC roof. The total roof size was approximately 8,000 SF, but unique because it used white PVC for the flat non-visible portions and Dark Lead Gray Decor PVC for the visible sloping roof portions. The Decor PVC roof mimics a standing seam metal roof, so it kept the same aesthetics as the previous roof but increased its performance.
