The National Roofing Contractors Association gave Korellis Roofing Inc. its Gold Circle Award in the “Outstanding Workmanship” category for its work on the circular two-story library’s roof, which is covered with native grasses. Commercial roofing and waterproofing systems manufacturer Sarnafil additionally named the Chicago Public Library’s green roof its Project of the Year.

Korellis Roofing, one of the largest roofing contractors in Northwest Indiana, installed the roof last year on the glassy, $19.1 million library branch on Chicago’s near south side.

The 66-year-old family-owned company also won Firestone Building Products 2016 Master Contractor and Inner Circle of Quality Award, two of the industry’s top honors. It’s the 24th year Korellis won the Master Contractor Award and the 23rd year it received the Inner Circle of Quality Award.
