SUPERSTRUCTURES provided investigation, design, and construction administration services to restore the penthouse roof of this 11-story residential building constructed in 1929. Restoration work included: removal of the existing, modified bitumen roof membrane and flashings; repair of the structurally sloped concrete roof deck; and installation of a new SBS modified bitumen membrane. The project also included: removal and replacement of brick masonry to accommodate new roof counter flashing; masonry repointing; in-kind replacement of roof drains; bulkhead and chimney stucco crack and spall repair; and installation of new parapet-mounted railings to achieve code-compliant height.
