Golden 1 Center is a landmark venue in downtown Sacramento, designed with sustainability and performance at its core. Its rooftop solar initiative called for a large-scale array across an expansive roof surface. It needed an attachment that could carry the array without causing leaks in the roof below.
The roof is a Johns Manville KEE system covering 7,800 squares. The solar racking had to be secured to it during active construction on a venue schedule that had no room to move, with long-term performance expected from a building that would be in the public eye from opening day.
THE CHALLENGE
Installing solar racking on a high-traffic, iconic structure introduced several competing demands: Maintaining watertight roof integrity on a KEE membrane system Supporting large-scale solar arrays across an expansive roof surface Ensuring long-term durability against wind uplift and environmental exposure Coordinating installation on a tight construction schedule for a major venue Solar is a long-horizon investment on a roof. The attachment has to outlast the racking, and an attachment that may cause leaks can do so years after anyone remembers who installed it.
THE SOLUTION
Anchor Products supplied U-Anchor® attachment engineered for solar racking on commercial roof systems. The installation went in during September 2016, ahead of the venue's opening. High-strength attachment for solar racking and array systems Compatible with Johns Manville KEE membrane roofs Compression-Free™ watertight seal at every attachment point Direct load transfer to structure, with the attachment a component of the roof The array went in on schedule with the roof system intact.
THE RESULT
The Golden 1 Center rooftop solar installation delivered a secure, durable attachment solution for one of the largest and most recognizable venues in California. It supports the facility's sustainability goals while preserving long-term roof performance. For solar EPCs and roofing contractors, the project demonstrates what large-scale array attachment looks like when the roof assembly is treated as a design constraint rather than an obstacle.
